Hi Lorena,

Thanks for completing the questionnaire so quickly! I don’t know if you’ve seen it yet, but the questionnaire was sent back to you with the following comments for correction:

Question 4.3 The W-9 submitted in Question 4.3 does not have a valid signature. Please submit a W-9 with an original "wet" ink signature or a digital adobe certificate signature with a timestamp. Copy-pasted, typed, and digitally drawn signatures will not be accepted. DocuSign signatures will not be accepted without a certificate of completion from DocuSign.

Question 6.1 Account holder name is a required field as it will integrate into the supplier's vendor master database. Account holder name should reflect supplier legal name submitted in 3.2. Also, please include Bank Control Key.

Question 6.4 Vendor’s Bank Contact information (Name in 6.4.1, Title in 6.4.2 and telephone number in 6.4.3) are required fields by the Treasury Dept and will integrate into the supplier's vendor master database. We can accept Customer Service for Contact Name and Title and general phone number for the bank.

Please let me know if you have any questions/let me know when you’ve submitted again with these corrections. Thanks!

Hi,

We are hoping to get Turnpack set up as a supplier with Northrop Grumman. To start this, we will need to send you our Supplier Registration Questionnaire. It includes questions about banking, taxes, compliance, capabilities, etc… and is housed on a site called Ariba. I have to send it to one POC to start, but then that person can invite others at your company to the questionnaire for help completing it as needed. Would you be the correct contact to send this initial invite to, or someone else?

Additionally, could you confirm:

Your company’s contractual address?
If the attached screenshot would be accurate for your company?

Thanks!! Please let me know if you have any questions.

Hi Lorena,

Sorry for the delayed response. When we open the W9, we can only see the signature part of your image below, not the digital timestamp info part to the right. I wonder if you expanded the box where the signature gets placed if we would be able to see the signature? Would you be able to try that? Let me know if you have questions.

Yes I am not sure what I am not understanding as I can see the digital timestamp. It was also rejecting saying it appeared to be a digital signature and it was not. So I am trying various ways to get it approved.

You can see below there is a timestamp signature.

Hi,

We are hoping to get Turnpack set up as a supplier with Northrop Grumman. To start this, we will need to send you our Supplier Registration Questionnaire. It includes questions about banking, taxes, compliance, capabilities, etc… and is housed on a site called Ariba. I have to send it to one POC to start, but then that person can invite others at your company to the questionnaire for help completing it as needed. Would you be the correct contact to send this initial invite to, or someone else?

Additionally, could you confirm:

Your company’s contractual address?
If the attached screenshot would be accurate for your company?

Sorry for the delayed response. When we open the W9, we can only see the signature part of your image below, not the digital timestamp info part to the right. I wonder if you expanded the box where the signature gets placed if we would be able to see the signature? Would you be able to try that? Let me know if you have questions.

Hi Lorena,

Thanks for completing the questionnaire so quickly! I don’t know if you’ve seen it yet, but the questionnaire was sent back to you with the following comments for correction:

Question 4.3 The W-9 submitted in Question 4.3 does not have a valid signature. Please submit a W-9 with an original "wet" ink signature or a digital adobe certificate signature with a timestamp. Copy-pasted, typed, and digitally drawn signatures will not be accepted. DocuSign signatures will not be accepted without a certificate of completion from DocuSign.

Question 6.1 Account holder name is a required field as it will integrate into the supplier's vendor master database. Account holder name should reflect supplier legal name submitted in 3.2. Also, please include Bank Control Key.

Question 6.4 Vendor’s Bank Contact information (Name in 6.4.1, Title in 6.4.2 and telephone number in 6.4.3) are required fields by the Treasury Dept and will integrate into the supplier's vendor master database. We can accept Customer Service for Contact Name and Title and general phone number for the bank.

Hi,

We are hoping to get Turnpack set up as a supplier with Northrop Grumman. To start this, we will need to send you our Supplier Registration Questionnaire. It includes questions about banking, taxes, compliance, capabilities, etc… and is housed on a site called Ariba. I have to send it to one POC to start, but then that person can invite others at your company to the questionnaire for help completing it as needed. Would you be the correct contact to send this initial invite to, or someone else?

Additionally, could you confirm:

Your company’s contractual address?
If the attached screenshot would be accurate for your company?

Thanks!! Please let me know if you have any questions.

Usually from what I’ve seen in the past, NG folks will reach out to schedule the service, then the service supplier will invoice our third party supplier. so in this case once the work is complete you’d send your invoice referencing NG PO 5000697353 to PB&J and they’ll invoice us directly.

Thanks!

Sorry for the delayed response. When we open the W9, we can only see the signature part of your image below, not the digital timestamp info part to the right. I wonder if you expanded the box where the signature gets placed if we would be able to see the signature? Would you be able to try that? Let me know if you have questions.

You can see below there is a timestamp signature.

Hi Lorena,

Thanks for completing the questionnaire so quickly! I don’t know if you’ve seen it yet, but the questionnaire was sent back to you with the following comments for correction:

Question 4.3 The W-9 submitted in Question 4.3 does not have a valid signature. Please submit a W-9 with an original "wet" ink signature or a digital adobe certificate signature with a timestamp. Copy-pasted, typed, and digitally drawn signatures will not be accepted. DocuSign signatures will not be accepted without a certificate of completion from DocuSign.

Question 6.1 Account holder name is a required field as it will integrate into the supplier's vendor master database. Account holder name should reflect supplier legal name submitted in 3.2. Also, please include Bank Control Key.

Question 6.4 Vendor’s Bank Contact information (Name in 6.4.1, Title in 6.4.2 and telephone number in 6.4.3) are required fields by the Treasury Dept and will integrate into the supplier's vendor master database. We can accept Customer Service for Contact Name and Title and general phone number for the bank.

Please let me know if you have any questions/let me know when you’ve submitted again with these corrections. Thanks!

David,

Sounds like you either have a vacuum issue for the component vacuum through the bond head or the BMC tool has some damage on it not sealing the vacuum properly when picking the BMC chip from the cavity. The Tool and Component vacuum are two separate lines.

Did you inspect the BMC tool surface?

Hi Chris,

Yes, the chip is there. I see what you mean about it having fiducials printed on it so you would know it is there. The chip stuck to my finger so I could lift it off. It is installed properly.

Today is the same as last Thursday. Starting auto-calibration, manually adjusting to the chip fiducials works but the chip is not being picked up. Vacuum on the tip feels strong on the BMC tip but vacuum through the tip does not appear to be enough to lift the chip. I am looking for an air leak. FYI, this machine has a vacuum pump, it does not use the vacuum port on the back of the machine.

Thank you,

Dave

HI Mike,

To answer your questions yes that is the BMC Chip but from the pictures David sent I think you already have this part. When you look at this image in the email for the part what I was trying to point out is that this chip has fiducials on them and when you look closely you'll see that they are plated onto the glass chip on one side. When this chip is loaded into the cavity on the machine (between the bond force sensor and the mini-BMC plate) it needs to be inserted with the chrome fiducials facing down. (if it's loaded with the chrome facing up you'll get a parallax when the substrate camera performs measurements of the chip on the mini-BMC plate and it will also set the uplooking camera focus height incorrectly).

Hope this helps. You guys did great work on your own, you are almost there.

Hello Chris,

Your instruction, tool ID picture below and several hours of technical support today are very much appreciated. Thank you for the fantastic support!

You helped me complete all the BH calibration routines today requiring superuser access. The BH appears to be operating as it should be.

Unfortunately, I am still stuck on the last step of auto-calibration and know why. The chip you were telling me was to be picked up from the BMC and placed 10-20 times is not there. There is no one sided chrome piece and I do not recall it ever being there. I will ask our BWI operations if they can send us one. That is the very last step of calibration before testing the tool bank.

There was a glass slide over the force sensor but that shattered last year. I was advised it is not needed and have run force calibration since then with no issues. If I am mistaken and this is the piece you were talking about, please let me know and I can request it. The below statement from the machine basics manual and leads me to think it might be the glass slide I need.

Best regards,

Dave

Hi Chris,

Good afternoon. On Friday, I tried to fix the theta offset by changing the values but did not have luck. Even when I had the BH tip and PU tool aligned, pick up still failed.

This morning, I noticed the BH tip spins freely, but when I change the direction of rotation, I feel a spot of resistance that goes away after 1 turn. Change rotation direction again and same result. I am speculating the internal encoder came loose. That would also help explain why the theta would not initialize for several days then started “working” again.

We have a bond head arriving from BWI as early as tomorrow. I received confirmation on which controller to purchase. We may have found one available.

Do you have any availability to come here and install the BH and Controller for us? If yes, may we please have a quote?

Hi Chris,

It was great to speak with you and thanks for the troubleshooting advice and support. For the tip vacuum issue, please note our machine is not hooked up to a vacuum line, our machine uses a venturi to generate the vacuum. I am headed to the machine to look for the module and check it, and fix the theta offset.

Thanks for the break-down. It sounds like you have multiple things going on. It's probably easiest if we jump on a call tomorrow. I have a meeting from approx. 8am-9am PST but you can give me a call before or after that, just give me a heads-up. From reviewing the logfiles and your summary I am seeing this timeline of events.

Hi Chris,

Thank you offering to help with our machine woes. This has been an evolving issue since January 13^th.

System info:

MC4 Datacon 2200 evo Automatic Dispense and Component Placement System

SN: 9502610007253

Our machine uses System 2 only and a non-heated bond head with magazine fed waffle packs.

Log files from the beginning of the issue on 1/13 and as of last Friday 1/29 are attached. Nothing of note has changed since last Friday. The January superuser PW expired.

Symptoms:

1/13: Alarm 2.2609: Initialization failed, Axis MtPPThetaSys2 could not be initialized (IMG_4034.jpg). A warning preceded this alarm by a day or two.

This alarm state lasted several days, maybe a week. After manually spinning the bond head tip, running Theta Axis calibration, and running the initialization routine repeatedly, the 2.2609 alarm resolved itself and the machine would successfully initialize.

After the theta initialization alarm was resolved, the pickup tip was rotated off center about 4 degrees (picture attached). The PU tip is no longer aligned with the PP tool locating pins and cannot pick tools up. The machine provides a message to manually place the tip on the bond head. This worked until yesterday. Currently, the machine does not recognize a tip manually placed onto the bond head. Increased vacuum did not resolve the issue. I have verified the tip is firmly in place. Maybe it is the vacuum switch but odd it decided to fail now. There are no hose leaks I can see or hear. I need to trace this farther upstream.

Currently, I need February’s superuser PW so I can recalibrate the bond head tip back to zero degrees. A request for the PW was sent to Besi. I have the UC Calibration tool on hand for this. Once that is resolved, the issue of the PU tip not being recognized by the machine remains. I am cautiously optimistic this will resolve itself or a root cause will be found.

Lastly, it appears the air bearing in the bond head is good. I push it up and it goes down by itself, no sticking. IMG_4116 shows the TD sensor value.

Thank you again for your time on this. I really appreciate the support. I can provide more details as needed. I did not attach videos due to file size.

Hi Chris –

Apologies for switching back over to e-mail (Dave informed me yesterday that you two were texting at this point), but Dave is out for a few days and I wanted to run a theory by you on the latest discovery on the machine. I’m assuming Dave let you know that he’s found the issue to be something to do with Z-axis. It’s not so much that the machine won’t pick up the chrome/glass chip due to vacuum (it will hold the part just fine if held directly to the nozzle, I’m told), but that the nozzle isn’t making contact with the chip.

The chip we are using is an older Besi PN, 04101310101. I’m told Besi has discontinued that part, with the new PN being 5001-9311. Long shot, but is there any chance there is a physical difference between the old and new part (thickness, maybe?) that could be contributing to this?

Sorry for the armchair QBing.

David,

Sounds like you either have a vacuum issue for the component vacuum through the bond head or the BMC tool has some damage on it not sealing the vacuum properly when picking the BMC chip from the cavity. The Tool and Component vacuum are two separate lines.

Did you inspect the BMC tool surface?

Chris

Hi Chris,

Yes, the chip is there. I see what you mean about it having fiducials printed on it so you would know it is there. The chip stuck to my finger so I could lift it off. It is installed properly.

Today is the same as last Thursday. Starting auto-calibration, manually adjusting to the chip fiducials works but the chip is not being picked up. Vacuum on the tip feels strong on the BMC tip but vacuum through the tip does not appear to be enough to lift the chip. I am looking for an air leak. FYI, this machine has a vacuum pump, it does not use the vacuum port on the back of the machine.

Thank you,

Dave

HI Mike,

To answer your questions yes that is the BMC Chip but from the pictures David sent I think you already have this part. When you look at this image in the email for the part what I was trying to point out is that this chip has fiducials on them and when you look closely you'll see that they are plated onto the glass chip on one side. When this chip is loaded into the cavity on the machine (between the bond force sensor and the mini-BMC plate) it needs to be inserted with the chrome fiducials facing down. (if it's loaded with the chrome facing up you'll get a parallax when the substrate camera performs measurements of the chip on the mini-BMC plate and it will also set the uplooking camera focus height incorrectly).

Hope this helps. You guys did great work on your own, you are almost there.

Hello Chris,

Your instruction, tool ID picture below and several hours of technical support today are very much appreciated. Thank you for the fantastic support!

You helped me complete all the BH calibration routines today requiring superuser access. The BH appears to be operating as it should be.

Unfortunately, I am still stuck on the last step of auto-calibration and know why. The chip you were telling me was to be picked up from the BMC and placed 10-20 times is not there. There is no one sided chrome piece and I do not recall it ever being there. I will ask our BWI operations if they can send us one. That is the very last step of calibration before testing the tool bank.

There was a glass slide over the force sensor but that shattered last year. I was advised it is not needed and have run force calibration since then with no issues. If I am mistaken and this is the piece you were talking about, please let me know and I can request it. The below statement from the machine basics manual and leads me to think it might be the glass slide I need.

Best regards,

Dave

Hi Chris,

Good afternoon. On Friday, I tried to fix the theta offset by changing the values but did not have luck. Even when I had the BH tip and PU tool aligned, pick up still failed.

This morning, I noticed the BH tip spins freely, but when I change the direction of rotation, I feel a spot of resistance that goes away after 1 turn. Change rotation direction again and same result. I am speculating the internal encoder came loose. That would also help explain why the theta would not initialize for several days then started “working” again.

We have a bond head arriving from BWI as early as tomorrow. I received confirmation on which controller to purchase. We may have found one available.

Do you have any availability to come here and install the BH and Controller for us? If yes, may we please have a quote?

It was great to speak with you and thanks for the troubleshooting advice and support. For the tip vacuum issue, please note our machine is not hooked up to a vacuum line, our machine uses a venturi to generate the vacuum. I am headed to the machine to look for the module and check it, and fix the theta offset.

Hi David,

Thanks for the break-down. It sounds like you have multiple things going on. It's probably easiest if we jump on a call tomorrow. I have a meeting from approx. 8am-9am PST but you can give me a call before or after that, just give me a heads-up. From reviewing the logfiles and your summary I am seeing this timeline of events. Let me know if this is incorrect. If the timeline is correct we should 'only' have to fix the 4deg offset and the tool detection?

Mike,

No worries. I just realized I typed up a reply to Dave last night in the text message but then got distracted and never hit send. The fact that it completes the first step with the touchdown tool and then fails the BMC pick-up is strange. Initially Dave didn't have the right Touchdown tool on hand and I can't remember if he did end up finding it. Can you confirm that the autocal is being performed with the below Touchdown tool and not the custom tool you use in production as TD tool.

David,

Sounds like you either have a vacuum issue for the component vacuum through the bond head or the BMC tool has some damage on it not sealing the vacuum properly when picking the BMC chip from the cavity. The Tool and Component vacuum are two separate lines.

Did you inspect the BMC tool surface?

Hi Chris,

Yes, the chip is there. I see what you mean about it having fiducials printed on it so you would know it is there. The chip stuck to my finger so I could lift it off. It is installed properly.

Today is the same as last Thursday. Starting auto-calibration, manually adjusting to the chip fiducials works but the chip is not being picked up. Vacuum on the tip feels strong on the BMC tip but vacuum through the tip does not appear to be enough to lift the chip. I am looking for an air leak. FYI, this machine has a vacuum pump, it does not use the vacuum port on the back of the machine.

Thank you,

HI Mike,

To answer your questions yes that is the BMC Chip but from the pictures David sent I think you already have this part. When you look at this image in the email for the part what I was trying to point out is that this chip has fiducials on them and when you look closely you'll see that they are plated onto the glass chip on one side. When this chip is loaded into the cavity on the machine (between the bond force sensor and the mini-BMC plate) it needs to be inserted with the chrome fiducials facing down. (if it's loaded with the chrome facing up you'll get a parallax when the substrate camera performs measurements of the chip on the mini-BMC plate and it will also set the uplooking camera focus height incorrectly).

Hope this helps. You guys did great work on your own, you are almost there.

Hello Chris,

Your instruction, tool ID picture below and several hours of technical support today are very much appreciated. Thank you for the fantastic support!

You helped me complete all the BH calibration routines today requiring superuser access. The BH appears to be operating as it should be.

Unfortunately, I am still stuck on the last step of auto-calibration and know why. The chip you were telling me was to be picked up from the BMC and placed 10-20 times is not there. There is no one sided chrome piece and I do not recall it ever being there. I will ask our BWI operations if they can send us one. That is the very last step of calibration before testing the tool bank.

There was a glass slide over the force sensor but that shattered last year. I was advised it is not needed and have run force calibration since then with no issues. If I am mistaken and this is the piece you were talking about, please let me know and I can request it. The below statement from the machine basics manual and leads me to think it might be the glass slide I need.

Best regards,

Dave

Hi Chris,

Good afternoon. On Friday, I tried to fix the theta offset by changing the values but did not have luck. Even when I had the BH tip and PU tool aligned, pick up still failed.

This morning, I noticed the BH tip spins freely, but when I change the direction of rotation, I feel a spot of resistance that goes away after 1 turn. Change rotation direction again and same result. I am speculating the internal encoder came loose. That would also help explain why the theta would not initialize for several days then started “working” again.

We have a bond head arriving from BWI as early as tomorrow. I received confirmation on which controller to purchase. We may have found one available.

Do you have any availability to come here and install the BH and Controller for us? If yes, may we please have a quote?

Hi Chris,

It was great to speak with you and thanks for the troubleshooting advice and support. For the tip vacuum issue, please note our machine is not hooked up to a vacuum line, our machine uses a venturi to generate the vacuum. I am headed to the machine to look for the module and check it, and fix the theta offset.

Hi David,

Thanks for the break-down. It sounds like you have multiple things going on. It's probably easiest if we jump on a call tomorrow. I have a meeting from approx. 8am-9am PST but you can give me a call before or after that, just give me a heads-up. From reviewing the logfiles and your summary I am seeing this timeline of events. Let me know if this is incorrect. If the timeline is correct we should 'only' have to fix the 4deg offset and the tool detection?

Time

Event

~Jan 11

Warning precedes the alarm (customer report)

Jan 13 09:51

First theta homing failure — tracking error + current limit

Jan 13 11:16

Shifts to Error 62 (index pulse not found), Alarm 2.2609

Jan 13 15:16-15:20

Multiple init attempts, all fail with Error 62

Jan 13–~Jan 20

Alarm state persists for ~1 week

~Jan 20

Manual spinning + repeated calibration resolves 2.2609

~Jan 20 onward

Theta homed but ~4° off center

Jan 29 12:23

Air pressure alarms appear (Error 2.501) (This was purposeful. I disconnected the vacuum line to the bond tip to check vacuum was strong. We have had zero air pressure alarms otherwise.)

Jan 29 13:43

Additional Z-axis position loss (This was odd. I was working with our technician to run the machine for solder dispense only, but a Z-axis alarm appeared. Recalibration of the Z-axis resolved the issue and it has yet to reappear. I took it as a symptom of the larger issue we are trying to get to the root of).

Jan 29 14:07-14:11

Tool vacuum check fails repeatedly (75-78, threshold 25-50) (This is the current state. It was OK earlier this week.)

Jan 29 14:34-15:06

Autocalibration fails — can't detect touchdown tool (Missing the PU tool due to the theta axis being off center.)

Jan 29 15:25

Bond force calibration fails

Jan 29 15:27-15:45

Continued tool detection failures during production attempts

Hi Chris,

Thank you offering to help with our machine woes. This has been an evolving issue since January 13^th.

System info:

MC4 Datacon 2200 evo Automatic Dispense and Component Placement System

SN: 9502610007253

Our machine uses System 2 only and a non-heated bond head with magazine fed waffle packs.

Log files from the beginning of the issue on 1/13 and as of last Friday 1/29 are attached. Nothing of note has changed since last Friday. The January superuser PW expired.

Symptoms:

1/13: Alarm 2.2609: Initialization failed, Axis MtPPThetaSys2 could not be initialized (IMG_4034.jpg). A warning preceded this alarm by a day or two.

This alarm state lasted several days, maybe a week. After manually spinning the bond head tip, running Theta Axis calibration, and running the initialization routine repeatedly, the 2.2609 alarm resolved itself and the machine would successfully initialize.

After the theta initialization alarm was resolved, the pickup tip was rotated off center about 4 degrees (picture attached). The PU tip is no longer aligned with the PP tool locating pins and cannot pick tools up. The machine provides a message to manually place the tip on the bond head. This worked until yesterday. Currently, the machine does not recognize a tip manually placed onto the bond head. Increased vacuum did not resolve the issue. I have verified the tip is firmly in place. Maybe it is the vacuum switch but odd it decided to fail now. There are no hose leaks I can see or hear. I need to trace this farther upstream.

Currently, I need February’s superuser PW so I can recalibrate the bond head tip back to zero degrees. A request for the PW was sent to Besi. I have the UC Calibration tool on hand for this. Once that is resolved, the issue of the PU tip not being recognized by the machine remains. I am cautiously optimistic this will resolve itself or a root cause will be found.

Lastly, it appears the air bearing in the bond head is good. I push it up and it goes down by itself, no sticking. IMG_4116 shows the TD sensor value.

Thank you again for your time on this. I really appreciate the support. I can provide more details as needed. I did not attach videos due to file size.

Hi Chris –

Admittedly, I’m not at all qualified to answer your question, though I’m certainly tracking the logic.

We’re at a critical point where it is imperative we get the machine back up and running ASAP. I know we have discussed the possibility of onsite support in the past. Is that still an option and, if so, could you provide an estimated date and a quote?

Many thanks!

Mike,

No worries. I just realized I typed up a reply to Dave last night in the text message but then got distracted and never hit send. The fact that it completes the first step with the touchdown tool and then fails the BMC pick-up is strange. Initially Dave didn't have the right Touchdown tool on hand and I can't remember if he did end up finding it. Can you confirm that the autocal is being performed with the below Touchdown tool and not the custom tool you use in production as TD tool.

Hi Chris –

Apologies for switching back over to e-mail (Dave informed me yesterday that you two were texting at this point), but Dave is out for a few days and I wanted to run a theory by you on the latest discovery on the machine. I’m assuming Dave let you know that he’s found the issue to be something to do with Z-axis. It’s not so much that the machine won’t pick up the chrome/glass chip due to vacuum (it will hold the part just fine if held directly to the nozzle, I’m told), but that the nozzle isn’t making contact with the chip.

The chip we are using is an older Besi PN, 04101310101. I’m told Besi has discontinued that part, with the new PN being 5001-9311. Long shot, but is there any chance there is a physical difference between the old and new part (thickness, maybe?) that could be contributing to this?

Sorry for the armchair QBing.

Thanks for the update, Dave.

Good to know about the venturi setup, obviously a vacuum pump would be preferred. Let me know what you find with the module and if you need anything else from my side. Hope the theta offset fix gets you back up and running.

Hi Chris,

Thank you offering to help with our machine woes. This has been an evolving issue since January 13^th.

System info:

MC4 Datacon 2200 evo Automatic Dispense and Component Placement System

SN: 9502610007253

Our machine uses System 2 only and a non-heated bond head with magazine fed waffle packs.

Log files from the beginning of the issue on 1/13 and as of last Friday 1/29 are attached. Nothing of note has changed since last Friday. The January superuser PW expired.

Symptoms:

1/13: Alarm 2.2609: Initialization failed, Axis MtPPThetaSys2 could not be initialized (IMG_4034.jpg). A warning preceded this alarm by a day or two.

This alarm state lasted several days, maybe a week. After manually spinning the bond head tip, running Theta Axis calibration, and running the initialization routine repeatedly, the 2.2609 alarm resolved itself and the machine would successfully initialize.

After the theta initialization alarm was resolved, the pickup tip was rotated off center about 4 degrees (picture attached). The PU tip is no longer aligned with the PP tool locating pins and cannot pick tools up. The machine provides a message to manually place the tip on the bond head. This worked until yesterday. Currently, the machine does not recognize a tip manually placed onto the bond head. Increased vacuum did not resolve the issue. I have verified the tip is firmly in place. Maybe it is the vacuum switch but odd it decided to fail now. There are no hose leaks I can see or hear. I need to trace this farther upstream.

Currently, I need February’s superuser PW so I can recalibrate the bond head tip back to zero degrees. A request for the PW was sent to Besi. I have the UC Calibration tool on hand for this. Once that is resolved, the issue of the PU tip not being recognized by the machine remains. I am cautiously optimistic this will resolve itself or a root cause will be found.

Lastly, it appears the air bearing in the bond head is good. I push it up and it goes down by itself, no sticking. IMG_4116 shows the TD sensor value.

Thank you again for your time on this. I really appreciate the support. I can provide more details as needed. I did not attach videos due to file size.

Re: EXT :Re: Re: Re: Re: Re: RE: Re: C Calibration RE: NGC San Diego Besi Machine Support

Hi Chris,

The issue is the BMC tool stops about 0.020” short of the glass chip. This is the step immediately after I auto cal uses the TD tool to touch off in the BMC and find the circular fiducials.

I tried it over and over, every time the BMC stops short and throws a vacuum sensing error because it thinks it is picking up the chip but is not.

Thank you,

Dave

Hi Chris –

Admittedly, I’m not at all qualified to answer your question, though I’m certainly tracking the logic.

We’re at a critical point where it is imperative we get the machine back up and running ASAP. I know we have discussed the possibility of onsite support in the past. Is that still an option and, if so, could you provide an estimated date and a quote?

Many thanks!

Mike,

No worries. I just realized I typed up a reply to Dave last night in the text message but then got distracted and never hit send. The fact that it completes the first step with the touchdown tool and then fails the BMC pick-up is strange. Initially Dave didn't have the right Touchdown tool on hand and I can't remember if he did end up finding it. Can you confirm that the autocal is being performed with the below Touchdown tool and not the custom tool you use in production as TD tool.

Chris

Hi Chris –

Apologies for switching back over to e-mail (Dave informed me yesterday that you two were texting at this point), but Dave is out for a few days and I wanted to run a theory by you on the latest discovery on the machine. I’m assuming Dave let you know that he’s found the issue to be something to do with Z-axis. It’s not so much that the machine won’t pick up the chrome/glass chip due to vacuum (it will hold the part just fine if held directly to the nozzle, I’m told), but that the nozzle isn’t making contact with the chip.

The chip we are using is an older Besi PN, 04101310101. I’m told Besi has discontinued that part, with the new PN being 5001-9311. Long shot, but is there any chance there is a physical difference between the old and new part (thickness, maybe?) that could be contributing to this?

Sorry for the armchair QBing.

David,

Sounds like you either have a vacuum issue for the component vacuum through the bond head or the BMC tool has some damage on it not sealing the vacuum properly when picking the BMC chip from the cavity. The Tool and Component vacuum are two separate lines.

Did you inspect the BMC tool surface?

Chris

Hi Chris,

Yes, the chip is there. I see what you mean about it having fiducials printed on it so you would know it is there. The chip stuck to my finger so I could lift it off. It is installed properly.

Today is the same as last Thursday. Starting auto-calibration, manually adjusting to the chip fiducials works but the chip is not being picked up. Vacuum on the tip feels strong on the BMC tip but vacuum through the tip does not appear to be enough to lift the chip. I am looking for an air leak. FYI, this machine has a vacuum pump, it does not use the vacuum port on the back of the machine.

Thank you,

Dave

HI Mike,

To answer your questions yes that is the BMC Chip but from the pictures David sent I think you already have this part. When you look at this image in the email for the part what I was trying to point out is that this chip has fiducials on them and when you look closely you'll see that they are plated onto the glass chip on one side. When this chip is loaded into the cavity on the machine (between the bond force sensor and the mini-BMC plate) it needs to be inserted with the chrome fiducials facing down. (if it's loaded with the chrome facing up you'll get a parallax when the substrate camera performs measurements of the chip on the mini-BMC plate and it will also set the uplooking camera focus height incorrectly).

Hope this helps. You guys did great work on your own, you are almost there.

Hello Chris,

Your instruction, tool ID picture below and several hours of technical support today are very much appreciated. Thank you for the fantastic support!

You helped me complete all the BH calibration routines today requiring superuser access. The BH appears to be operating as it should be.

Unfortunately, I am still stuck on the last step of auto-calibration and know why. The chip you were telling me was to be picked up from the BMC and placed 10-20 times is not there. There is no one sided chrome piece and I do not recall it ever being there. I will ask our BWI operations if they can send us one. That is the very last step of calibration before testing the tool bank.

There was a glass slide over the force sensor but that shattered last year. I was advised it is not needed and have run force calibration since then with no issues. If I am mistaken and this is the piece you were talking about, please let me know and I can request it. The below statement from the machine basics manual and leads me to think it might be the glass slide I need.

Best regards,

Dave

Hi Chris,

Good afternoon. On Friday, I tried to fix the theta offset by changing the values but did not have luck. Even when I had the BH tip and PU tool aligned, pick up still failed.

This morning, I noticed the BH tip spins freely, but when I change the direction of rotation, I feel a spot of resistance that goes away after 1 turn. Change rotation direction again and same result. I am speculating the internal encoder came loose. That would also help explain why the theta would not initialize for several days then started “working” again.

We have a bond head arriving from BWI as early as tomorrow. I received confirmation on which controller to purchase. We may have found one available.

Do you have any availability to come here and install the BH and Controller for us? If yes, may we please have a quote?

Dave,

I sent you a text message to check if you can access an assistant to reteach the cavity position for the BMC chip. This should address the pick-up issue. The mental issue I am having is since we only replaced the bond head I am not sure why it would be off. Even if you get the machine running which is priority #1 I think we should still plan for me to come onsite to do a thorough PM and calibration so we have a known good status of the system.

If you can't get it up and running I can probably be onsite next Wednesday.

Hi Chris,

The issue is the BMC tool stops about 0.020” short of the glass chip. This is the step immediately after I auto cal uses the TD tool to touch off in the BMC and find the circular fiducials.

I tried it over and over, every time the BMC stops short and throws a vacuum sensing error because it thinks it is picking up the chip but is not.

Thank you,

Dave

Hi Chris –

Admittedly, I’m not at all qualified to answer your question, though I’m certainly tracking the logic.

We’re at a critical point where it is imperative we get the machine back up and running ASAP. I know we have discussed the possibility of onsite support in the past. Is that still an option and, if so, could you provide an estimated date and a quote?

Many thanks!

Mike,

No worries. I just realized I typed up a reply to Dave last night in the text message but then got distracted and never hit send. The fact that it completes the first step with the touchdown tool and then fails the BMC pick-up is strange. Initially Dave didn't have the right Touchdown tool on hand and I can't remember if he did end up finding it. Can you confirm that the autocal is being performed with the below Touchdown tool and not the custom tool you use in production as TD tool.

Chris

Hi Chris –

Apologies for switching back over to e-mail (Dave informed me yesterday that you two were texting at this point), but Dave is out for a few days and I wanted to run a theory by you on the latest discovery on the machine. I’m assuming Dave let you know that he’s found the issue to be something to do with Z-axis. It’s not so much that the machine won’t pick up the chrome/glass chip due to vacuum (it will hold the part just fine if held directly to the nozzle, I’m told), but that the nozzle isn’t making contact with the chip.

The chip we are using is an older Besi PN, 04101310101. I’m told Besi has discontinued that part, with the new PN being 5001-9311. Long shot, but is there any chance there is a physical difference between the old and new part (thickness, maybe?) that could be contributing to this?

Sorry for the armchair QBing.

David,

Sounds like you either have a vacuum issue for the component vacuum through the bond head or the BMC tool has some damage on it not sealing the vacuum properly when picking the BMC chip from the cavity. The Tool and Component vacuum are two separate lines.

Did you inspect the BMC tool surface?

Chris

Hi Chris,

Yes, the chip is there. I see what you mean about it having fiducials printed on it so you would know it is there. The chip stuck to my finger so I could lift it off. It is installed properly.

Today is the same as last Thursday. Starting auto-calibration, manually adjusting to the chip fiducials works but the chip is not being picked up. Vacuum on the tip feels strong on the BMC tip but vacuum through the tip does not appear to be enough to lift the chip. I am looking for an air leak. FYI, this machine has a vacuum pump, it does not use the vacuum port on the back of the machine.

Thank you,

Dave

HI Mike,

To answer your questions yes that is the BMC Chip but from the pictures David sent I think you already have this part. When you look at this image in the email for the part what I was trying to point out is that this chip has fiducials on them and when you look closely you'll see that they are plated onto the glass chip on one side. When this chip is loaded into the cavity on the machine (between the bond force sensor and the mini-BMC plate) it needs to be inserted with the chrome fiducials facing down. (if it's loaded with the chrome facing up you'll get a parallax when the substrate camera performs measurements of the chip on the mini-BMC plate and it will also set the uplooking camera focus height incorrectly).

Hope this helps. You guys did great work on your own, you are almost there.

Hello Chris,

Your instruction, tool ID picture below and several hours of technical support today are very much appreciated. Thank you for the fantastic support!

You helped me complete all the BH calibration routines today requiring superuser access. The BH appears to be operating as it should be.

Unfortunately, I am still stuck on the last step of auto-calibration and know why. The chip you were telling me was to be picked up from the BMC and placed 10-20 times is not there. There is no one sided chrome piece and I do not recall it ever being there. I will ask our BWI operations if they can send us one. That is the very last step of calibration before testing the tool bank.

There was a glass slide over the force sensor but that shattered last year. I was advised it is not needed and have run force calibration since then with no issues. If I am mistaken and this is the piece you were talking about, please let me know and I can request it. The below statement from the machine basics manual and leads me to think it might be the glass slide I need.

Best regards,

Dave

Hi Chris,

Good afternoon. On Friday, I tried to fix the theta offset by changing the values but did not have luck. Even when I had the BH tip and PU tool aligned, pick up still failed.

This morning, I noticed the BH tip spins freely, but when I change the direction of rotation, I feel a spot of resistance that goes away after 1 turn. Change rotation direction again and same result. I am speculating the internal encoder came loose. That would also help explain why the theta would not initialize for several days then started “working” again.

We have a bond head arriving from BWI as early as tomorrow. I received confirmation on which controller to purchase. We may have found one available.

Do you have any availability to come here and install the BH and Controller for us? If yes, may we please have a quote?

It was great to speak with you and thanks for the troubleshooting advice and support. For the tip vacuum issue, please note our machine is not hooked up to a vacuum line, our machine uses a venturi to generate the vacuum. I am headed to the machine to look for the module and check it, and fix the theta offset.

Hi David,

Thanks for the break-down. It sounds like you have multiple things going on. It's probably easiest if we jump on a call tomorrow. I have a meeting from approx. 8am-9am PST but you can give me a call before or after that, just give me a heads-up. From reviewing the logfiles and your summary I am seeing this timeline of events. Let me know if this is incorrect. If the timeline is correct we should 'only' have to fix the 4deg offset and the tool detection?

Hi Chris,

Thank you offering to help with our machine woes. This has been an evolving issue since January 13^th.

System info:

MC4 Datacon 2200 evo Automatic Dispense and Component Placement System

SN: 9502610007253

Our machine uses System 2 only and a non-heated bond head with magazine fed waffle packs.

Log files from the beginning of the issue on 1/13 and as of last Friday 1/29 are attached. Nothing of note has changed since last Friday. The January superuser PW expired.

Symptoms:

1/13: Alarm 2.2609: Initialization failed, Axis MtPPThetaSys2 could not be initialized (IMG_4034.jpg). A warning preceded this alarm by a day or two.

This alarm state lasted several days, maybe a week. After manually spinning the bond head tip, running Theta Axis calibration, and running the initialization routine repeatedly, the 2.2609 alarm resolved itself and the machine would successfully initialize.

After the theta initialization alarm was resolved, the pickup tip was rotated off center about 4 degrees (picture attached). The PU tip is no longer aligned with the PP tool locating pins and cannot pick tools up. The machine provides a message to manually place the tip on the bond head. This worked until yesterday. Currently, the machine does not recognize a tip manually placed onto the bond head. Increased vacuum did not resolve the issue. I have verified the tip is firmly in place. Maybe it is the vacuum switch but odd it decided to fail now. There are no hose leaks I can see or hear. I need to trace this farther upstream.

Currently, I need February’s superuser PW so I can recalibrate the bond head tip back to zero degrees. A request for the PW was sent to Besi. I have the UC Calibration tool on hand for this. Once that is resolved, the issue of the PU tip not being recognized by the machine remains. I am cautiously optimistic this will resolve itself or a root cause will be found.

Lastly, it appears the air bearing in the bond head is good. I push it up and it goes down by itself, no sticking. IMG_4116 shows the TD sensor value.

Thank you again for your time on this. I really appreciate the support. I can provide more details as needed. I did not attach videos due to file size.

Chris,

Thanks for sending those messages. I am back in the office today.

I think the TD pickup Z position for the chip is off because we were using a non-standard TD tool. The machine is programmed for the longer TD tool.

I am headed out to change this Z value slightly to see if it will change the Z position. If it does my plan is to reduce the Z height until it touches and picks up the chip.

Please let me know your ETA tomorrow. As Mike said, just bring an ID. I must escort you while you are here, but we will be in a regular production area.

Dave,

I sent you a text message to check if you can access an assistant to reteach the cavity position for the BMC chip. This should address the pick-up issue. The mental issue I am having is since we only replaced the bond head I am not sure why it would be off. Even if you get the machine running which is priority #1 I think we should still plan for me to come onsite to do a thorough PM and calibration so we have a known good status of the system.

If you can't get it up and running I can probably be onsite next Wednesday.

Hi Chris,

The issue is the BMC tool stops about 0.020” short of the glass chip. This is the step immediately after I auto cal uses the TD tool to touch off in the BMC and find the circular fiducials.

I tried it over and over, every time the BMC stops short and throws a vacuum sensing error because it thinks it is picking up the chip but is not.

Hi Chris –

Admittedly, I’m not at all qualified to answer your question, though I’m certainly tracking the logic.

We’re at a critical point where it is imperative we get the machine back up and running ASAP. I know we have discussed the possibility of onsite support in the past. Is that still an option and, if so, could you provide an estimated date and a quote?

Many thanks!

Mike,

No worries. I just realized I typed up a reply to Dave last night in the text message but then got distracted and never hit send. The fact that it completes the first step with the touchdown tool and then fails the BMC pick-up is strange. Initially Dave didn't have the right Touchdown tool on hand and I can't remember if he did end up finding it. Can you confirm that the autocal is being performed with the below Touchdown tool and not the custom tool you use in production as TD tool.

Chris

Hi Chris –

Apologies for switching back over to e-mail (Dave informed me yesterday that you two were texting at this point), but Dave is out for a few days and I wanted to run a theory by you on the latest discovery on the machine. I’m assuming Dave let you know that he’s found the issue to be something to do with Z-axis. It’s not so much that the machine won’t pick up the chrome/glass chip due to vacuum (it will hold the part just fine if held directly to the nozzle, I’m told), but that the nozzle isn’t making contact with the chip.

The chip we are using is an older Besi PN, 04101310101. I’m told Besi has discontinued that part, with the new PN being 5001-9311. Long shot, but is there any chance there is a physical difference between the old and new part (thickness, maybe?) that could be contributing to this?

Sorry for the armchair QBing.

David,

Sounds like you either have a vacuum issue for the component vacuum through the bond head or the BMC tool has some damage on it not sealing the vacuum properly when picking the BMC chip from the cavity. The Tool and Component vacuum are two separate lines.

Did you inspect the BMC tool surface?

Chris

Hi Chris,

Yes, the chip is there. I see what you mean about it having fiducials printed on it so you would know it is there. The chip stuck to my finger so I could lift it off. It is installed properly.

Today is the same as last Thursday. Starting auto-calibration, manually adjusting to the chip fiducials works but the chip is not being picked up. Vacuum on the tip feels strong on the BMC tip but vacuum through the tip does not appear to be enough to lift the chip. I am looking for an air leak. FYI, this machine has a vacuum pump, it does not use the vacuum port on the back of the machine.

Thank you,

Dave

HI Mike,

To answer your questions yes that is the BMC Chip but from the pictures David sent I think you already have this part. When you look at this image in the email for the part what I was trying to point out is that this chip has fiducials on them and when you look closely you'll see that they are plated onto the glass chip on one side. When this chip is loaded into the cavity on the machine (between the bond force sensor and the mini-BMC plate) it needs to be inserted with the chrome fiducials facing down. (if it's loaded with the chrome facing up you'll get a parallax when the substrate camera performs measurements of the chip on the mini-BMC plate and it will also set the uplooking camera focus height incorrectly).

Hope this helps. You guys did great work on your own, you are almost there.

Hello Chris,

Your instruction, tool ID picture below and several hours of technical support today are very much appreciated. Thank you for the fantastic support!

You helped me complete all the BH calibration routines today requiring superuser access. The BH appears to be operating as it should be.

Unfortunately, I am still stuck on the last step of auto-calibration and know why. The chip you were telling me was to be picked up from the BMC and placed 10-20 times is not there. There is no one sided chrome piece and I do not recall it ever being there. I will ask our BWI operations if they can send us one. That is the very last step of calibration before testing the tool bank.

There was a glass slide over the force sensor but that shattered last year. I was advised it is not needed and have run force calibration since then with no issues. If I am mistaken and this is the piece you were talking about, please let me know and I can request it. The below statement from the machine basics manual and leads me to think it might be the glass slide I need.

Best regards,

Dave

Hi Chris,

Good afternoon. On Friday, I tried to fix the theta offset by changing the values but did not have luck. Even when I had the BH tip and PU tool aligned, pick up still failed.

This morning, I noticed the BH tip spins freely, but when I change the direction of rotation, I feel a spot of resistance that goes away after 1 turn. Change rotation direction again and same result. I am speculating the internal encoder came loose. That would also help explain why the theta would not initialize for several days then started “working” again.

We have a bond head arriving from BWI as early as tomorrow. I received confirmation on which controller to purchase. We may have found one available.

Do you have any availability to come here and install the BH and Controller for us? If yes, may we please have a quote?

Hi David,

Thanks for the break-down. It sounds like you have multiple things going on. It's probably easiest if we jump on a call tomorrow. I have a meeting from approx. 8am-9am PST but you can give me a call before or after that, just give me a heads-up. From reviewing the logfiles and your summary I am seeing this timeline of events. Let me know if this is incorrect. If the timeline is correct we should 'only' have to fix the 4deg offset and the tool detection?

Time

Event

~Jan 11

Warning precedes the alarm (customer report)

Additional Z-axis position loss (This was odd. I was working with our technician to run the machine for solder dispense only, but a Z-axis alarm appeared. Recalibration of the Z-axis resolved the issue and it has yet to reappear. I took it as a symptom of the larger issue we are trying to get to the root of).

Jan 29 14:07-14:11

Tool vacuum check fails repeatedly (75-78, threshold 25-50) (This is the current state. It was OK earlier this week.)

Hi Chris,

Thank you offering to help with our machine woes. This has been an evolving issue since January 13^th.

System info:

MC4 Datacon 2200 evo Automatic Dispense and Component Placement System

SN: 9502610007253

Our machine uses System 2 only and a non-heated bond head with magazine fed waffle packs.

Log files from the beginning of the issue on 1/13 and as of last Friday 1/29 are attached. Nothing of note has changed since last Friday. The January superuser PW expired.

Symptoms:

1/13: Alarm 2.2609: Initialization failed, Axis MtPPThetaSys2 could not be initialized (IMG_4034.jpg). A warning preceded this alarm by a day or two.

This alarm state lasted several days, maybe a week. After manually spinning the bond head tip, running Theta Axis calibration, and running the initialization routine repeatedly, the 2.2609 alarm resolved itself and the machine would successfully initialize.

After the theta initialization alarm was resolved, the pickup tip was rotated off center about 4 degrees (picture attached). The PU tip is no longer aligned with the PP tool locating pins and cannot pick tools up. The machine provides a message to manually place the tip on the bond head. This worked until yesterday. Currently, the machine does not recognize a tip manually placed onto the bond head. Increased vacuum did not resolve the issue. I have verified the tip is firmly in place. Maybe it is the vacuum switch but odd it decided to fail now. There are no hose leaks I can see or hear. I need to trace this farther upstream.

Currently, I need February’s superuser PW so I can recalibrate the bond head tip back to zero degrees. A request for the PW was sent to Besi. I have the UC Calibration tool on hand for this. Once that is resolved, the issue of the PU tip not being recognized by the machine remains. I am cautiously optimistic this will resolve itself or a root cause will be found.

Lastly, it appears the air bearing in the bond head is good. I push it up and it goes down by itself, no sticking. IMG_4116 shows the TD sensor value.

Thank you again for your time on this. I really appreciate the support. I can provide more details as needed. I did not attach videos due to file size.

Hi Chris,

Great. Please text me at 8588609985 when you get here.

I have the correct TD Tool and used it for the auto-calibration. Trying a Z height change. The other tool was longer so logically the correct tool will stop short.

Chris,

Thanks for sending those messages. I am back in the office today.

I think the TD pickup Z position for the chip is off because we were using a non-standard TD tool. The machine is programmed for the longer TD tool.

I am headed out to change this Z value slightly to see if it will change the Z position. If it does my plan is to reduce the Z height until it touches and picks up the chip.

Please let me know your ETA tomorrow. As Mike said, just bring an ID. I must escort you while you are here, but we will be in a regular production area.

No worries. I just realized I typed up a reply to Dave last night in the text message but then got distracted and never hit send. The fact that it completes the first step with the touchdown tool and then fails the BMC pick-up is strange. Initially Dave didn't have the right Touchdown tool on hand and I can't remember if he did end up finding it. Can you confirm that the autocal is being performed with the below Touchdown tool and not the custom tool you use in production as TD tool.

Hi Chris –

Apologies for switching back over to e-mail (Dave informed me yesterday that you two were texting at this point), but Dave is out for a few days and I wanted to run a theory by you on the latest discovery on the machine. I’m assuming Dave let you know that he’s found the issue to be something to do with Z-axis. It’s not so much that the machine won’t pick up the chrome/glass chip due to vacuum (it will hold the part just fine if held directly to the nozzle, I’m told), but that the nozzle isn’t making contact with the chip.

The chip we are using is an older Besi PN, 04101310101. I’m told Besi has discontinued that part, with the new PN being 5001-9311. Long shot, but is there any chance there is a physical difference between the old and new part (thickness, maybe?) that could be contributing to this?

Sorry for the armchair QBing.

David,

Sounds like you either have a vacuum issue for the component vacuum through the bond head or the BMC tool has some damage on it not sealing the vacuum properly when picking the BMC chip from the cavity. The Tool and Component vacuum are two separate lines.

Did you inspect the BMC tool surface?

Hi Chris,

Yes, the chip is there. I see what you mean about it having fiducials printed on it so you would know it is there. The chip stuck to my finger so I could lift it off. It is installed properly.

Today is the same as last Thursday. Starting auto-calibration, manually adjusting to the chip fiducials works but the chip is not being picked up. Vacuum on the tip feels strong on the BMC tip but vacuum through the tip does not appear to be enough to lift the chip. I am looking for an air leak. FYI, this machine has a vacuum pump, it does not use the vacuum port on the back of the machine.

Thank you,

Dave

HI Mike,

To answer your questions yes that is the BMC Chip but from the pictures David sent I think you already have this part. When you look at this image in the email for the part what I was trying to point out is that this chip has fiducials on them and when you look closely you'll see that they are plated onto the glass chip on one side. When this chip is loaded into the cavity on the machine (between the bond force sensor and the mini-BMC plate) it needs to be inserted with the chrome fiducials facing down. (if it's loaded with the chrome facing up you'll get a parallax when the substrate camera performs measurements of the chip on the mini-BMC plate and it will also set the uplooking camera focus height incorrectly).

Hope this helps. You guys did great work on your own, you are almost there.

Hello Chris,

Your instruction, tool ID picture below and several hours of technical support today are very much appreciated. Thank you for the fantastic support!

You helped me complete all the BH calibration routines today requiring superuser access. The BH appears to be operating as it should be.

Unfortunately, I am still stuck on the last step of auto-calibration and know why. The chip you were telling me was to be picked up from the BMC and placed 10-20 times is not there. There is no one sided chrome piece and I do not recall it ever being there. I will ask our BWI operations if they can send us one. That is the very last step of calibration before testing the tool bank.

There was a glass slide over the force sensor but that shattered last year. I was advised it is not needed and have run force calibration since then with no issues. If I am mistaken and this is the piece you were talking about, please let me know and I can request it. The below statement from the machine basics manual and leads me to think it might be the glass slide I need.

Best regards,

Dave

Hi Chris,

Good afternoon. On Friday, I tried to fix the theta offset by changing the values but did not have luck. Even when I had the BH tip and PU tool aligned, pick up still failed.

This morning, I noticed the BH tip spins freely, but when I change the direction of rotation, I feel a spot of resistance that goes away after 1 turn. Change rotation direction again and same result. I am speculating the internal encoder came loose. That would also help explain why the theta would not initialize for several days then started “working” again.

We have a bond head arriving from BWI as early as tomorrow. I received confirmation on which controller to purchase. We may have found one available.

Do you have any availability to come here and install the BH and Controller for us? If yes, may we please have a quote?

Hi David,

Thanks for the break-down. It sounds like you have multiple things going on. It's probably easiest if we jump on a call tomorrow. I have a meeting from approx. 8am-9am PST but you can give me a call before or after that, just give me a heads-up. From reviewing the logfiles and your summary I am seeing this timeline of events. Let me know if this is incorrect. If the timeline is correct we should 'only' have to fix the 4deg offset and the tool detection?

Additional Z-axis position loss (This was odd. I was working with our technician to run the machine for solder dispense only, but a Z-axis alarm appeared. Recalibration of the Z-axis resolved the issue and it has yet to reappear. I took it as a symptom of the larger issue we are trying to get to the root of).

Hi Chris,

Thank you offering to help with our machine woes. This has been an evolving issue since January 13^th.

System info:

MC4 Datacon 2200 evo Automatic Dispense and Component Placement System

SN: 9502610007253

Our machine uses System 2 only and a non-heated bond head with magazine fed waffle packs.

Log files from the beginning of the issue on 1/13 and as of last Friday 1/29 are attached. Nothing of note has changed since last Friday. The January superuser PW expired.

Symptoms:

1/13: Alarm 2.2609: Initialization failed, Axis MtPPThetaSys2 could not be initialized (IMG_4034.jpg). A warning preceded this alarm by a day or two.

This alarm state lasted several days, maybe a week. After manually spinning the bond head tip, running Theta Axis calibration, and running the initialization routine repeatedly, the 2.2609 alarm resolved itself and the machine would successfully initialize.

After the theta initialization alarm was resolved, the pickup tip was rotated off center about 4 degrees (picture attached). The PU tip is no longer aligned with the PP tool locating pins and cannot pick tools up. The machine provides a message to manually place the tip on the bond head. This worked until yesterday. Currently, the machine does not recognize a tip manually placed onto the bond head. Increased vacuum did not resolve the issue. I have verified the tip is firmly in place. Maybe it is the vacuum switch but odd it decided to fail now. There are no hose leaks I can see or hear. I need to trace this farther upstream.

Currently, I need February’s superuser PW so I can recalibrate the bond head tip back to zero degrees. A request for the PW was sent to Besi. I have the UC Calibration tool on hand for this. Once that is resolved, the issue of the PU tip not being recognized by the machine remains. I am cautiously optimistic this will resolve itself or a root cause will be found.

Lastly, it appears the air bearing in the bond head is good. I push it up and it goes down by itself, no sticking. IMG_4116 shows the TD sensor value.

Thank you again for your time on this. I really appreciate the support. I can provide more details as needed. I did not attach videos due to file size.

I have the correct TD Tool and used it for the auto-calibration. Trying a Z height change. The other tool was longer so logically the correct tool will stop short.

Chris,

Thanks for sending those messages. I am back in the office today.

I think the TD pickup Z position for the chip is off because we were using a non-standard TD tool. The machine is programmed for the longer TD tool.

I am headed out to change this Z value slightly to see if it will change the Z position. If it does my plan is to reduce the Z height until it touches and picks up the chip.

Please let me know your ETA tomorrow. As Mike said, just bring an ID. I must escort you while you are here, but we will be in a regular production area.

Dave,

I sent you a text message to check if you can access an assistant to reteach the cavity position for the BMC chip. This should address the pick-up issue. The mental issue I am having is since we only replaced the bond head I am not sure why it would be off. Even if you get the machine running which is priority #1 I think we should still plan for me to come onsite to do a thorough PM and calibration so we have a known good status of the system.

If you can't get it up and running I can probably be onsite next Wednesday.

Hi Chris,

The issue is the BMC tool stops about 0.020” short of the glass chip. This is the step immediately after I auto cal uses the TD tool to touch off in the BMC and find the circular fiducials.

I tried it over and over, every time the BMC stops short and throws a vacuum sensing error because it thinks it is picking up the chip but is not.

Thank you,

No worries. I just realized I typed up a reply to Dave last night in the text message but then got distracted and never hit send. The fact that it completes the first step with the touchdown tool and then fails the BMC pick-up is strange. Initially Dave didn't have the right Touchdown tool on hand and I can't remember if he did end up finding it. Can you confirm that the autocal is being performed with the below Touchdown tool and not the custom tool you use in production as TD tool.

Hi Chris –

Apologies for switching back over to e-mail (Dave informed me yesterday that you two were texting at this point), but Dave is out for a few days and I wanted to run a theory by you on the latest discovery on the machine. I’m assuming Dave let you know that he’s found the issue to be something to do with Z-axis. It’s not so much that the machine won’t pick up the chrome/glass chip due to vacuum (it will hold the part just fine if held directly to the nozzle, I’m told), but that the nozzle isn’t making contact with the chip.

The chip we are using is an older Besi PN, 04101310101. I’m told Besi has discontinued that part, with the new PN being 5001-9311. Long shot, but is there any chance there is a physical difference between the old and new part (thickness, maybe?) that could be contributing to this?

Sorry for the armchair QBing.

David,

Sounds like you either have a vacuum issue for the component vacuum through the bond head or the BMC tool has some damage on it not sealing the vacuum properly when picking the BMC chip from the cavity. The Tool and Component vacuum are two separate lines.

Did you inspect the BMC tool surface?

Hi Chris,

Yes, the chip is there. I see what you mean about it having fiducials printed on it so you would know it is there. The chip stuck to my finger so I could lift it off. It is installed properly.

Today is the same as last Thursday. Starting auto-calibration, manually adjusting to the chip fiducials works but the chip is not being picked up. Vacuum on the tip feels strong on the BMC tip but vacuum through the tip does not appear to be enough to lift the chip. I am looking for an air leak. FYI, this machine has a vacuum pump, it does not use the vacuum port on the back of the machine.

Thank you,

Dave

HI Mike,

To answer your questions yes that is the BMC Chip but from the pictures David sent I think you already have this part. When you look at this image in the email for the part what I was trying to point out is that this chip has fiducials on them and when you look closely you'll see that they are plated onto the glass chip on one side. When this chip is loaded into the cavity on the machine (between the bond force sensor and the mini-BMC plate) it needs to be inserted with the chrome fiducials facing down. (if it's loaded with the chrome facing up you'll get a parallax when the substrate camera performs measurements of the chip on the mini-BMC plate and it will also set the uplooking camera focus height incorrectly).

Hope this helps. You guys did great work on your own, you are almost there.

Hello Chris,

Your instruction, tool ID picture below and several hours of technical support today are very much appreciated. Thank you for the fantastic support!

You helped me complete all the BH calibration routines today requiring superuser access. The BH appears to be operating as it should be.

Unfortunately, I am still stuck on the last step of auto-calibration and know why. The chip you were telling me was to be picked up from the BMC and placed 10-20 times is not there. There is no one sided chrome piece and I do not recall it ever being there. I will ask our BWI operations if they can send us one. That is the very last step of calibration before testing the tool bank.

There was a glass slide over the force sensor but that shattered last year. I was advised it is not needed and have run force calibration since then with no issues. If I am mistaken and this is the piece you were talking about, please let me know and I can request it. The below statement from the machine basics manual and leads me to think it might be the glass slide I need.

Best regards,

Dave

Hi Chris,

Good afternoon. On Friday, I tried to fix the theta offset by changing the values but did not have luck. Even when I had the BH tip and PU tool aligned, pick up still failed.

This morning, I noticed the BH tip spins freely, but when I change the direction of rotation, I feel a spot of resistance that goes away after 1 turn. Change rotation direction again and same result. I am speculating the internal encoder came loose. That would also help explain why the theta would not initialize for several days then started “working” again.

We have a bond head arriving from BWI as early as tomorrow. I received confirmation on which controller to purchase. We may have found one available.

Do you have any availability to come here and install the BH and Controller for us? If yes, may we please have a quote?

Hi David,

Thanks for the break-down. It sounds like you have multiple things going on. It's probably easiest if we jump on a call tomorrow. I have a meeting from approx. 8am-9am PST but you can give me a call before or after that, just give me a heads-up. From reviewing the logfiles and your summary I am seeing this timeline of events. Let me know if this is incorrect. If the timeline is correct we should 'only' have to fix the 4deg offset and the tool detection?

Additional Z-axis position loss (This was odd. I was working with our technician to run the machine for solder dispense only, but a Z-axis alarm appeared. Recalibration of the Z-axis resolved the issue and it has yet to reappear. I took it as a symptom of the larger issue we are trying to get to the root of).

Jan 29 14:07-14:11

Tool vacuum check fails repeatedly (75-78, threshold 25-50) (This is the current state. It was OK earlier this week.)

Hi Chris,

Thank you offering to help with our machine woes. This has been an evolving issue since January 13^th.

System info:

MC4 Datacon 2200 evo Automatic Dispense and Component Placement System

SN: 9502610007253

Our machine uses System 2 only and a non-heated bond head with magazine fed waffle packs.

Log files from the beginning of the issue on 1/13 and as of last Friday 1/29 are attached. Nothing of note has changed since last Friday. The January superuser PW expired.

Symptoms:

1/13: Alarm 2.2609: Initialization failed, Axis MtPPThetaSys2 could not be initialized (IMG_4034.jpg). A warning preceded this alarm by a day or two.

This alarm state lasted several days, maybe a week. After manually spinning the bond head tip, running Theta Axis calibration, and running the initialization routine repeatedly, the 2.2609 alarm resolved itself and the machine would successfully initialize.

After the theta initialization alarm was resolved, the pickup tip was rotated off center about 4 degrees (picture attached). The PU tip is no longer aligned with the PP tool locating pins and cannot pick tools up. The machine provides a message to manually place the tip on the bond head. This worked until yesterday. Currently, the machine does not recognize a tip manually placed onto the bond head. Increased vacuum did not resolve the issue. I have verified the tip is firmly in place. Maybe it is the vacuum switch but odd it decided to fail now. There are no hose leaks I can see or hear. I need to trace this farther upstream.

Currently, I need February’s superuser PW so I can recalibrate the bond head tip back to zero degrees. A request for the PW was sent to Besi. I have the UC Calibration tool on hand for this. Once that is resolved, the issue of the PU tip not being recognized by the machine remains. I am cautiously optimistic this will resolve itself or a root cause will be found.

Lastly, it appears the air bearing in the bond head is good. I push it up and it goes down by itself, no sticking. IMG_4116 shows the TD sensor value.

Thank you again for your time on this. I really appreciate the support. I can provide more details as needed. I did not attach videos due to file size.

Thanks again for your time today. It was great to meet you.

A list of items from today:

List of common failures and associated parts we should have on-hand. I noted the spare contactors, fuses, switch away from the vacuum pump, new glass slides. Controller(s)?
Your assessment of any PMs we appear to be behind on or not performing. (i.e. our missing force gage calibration tool means we are not calibrating the high and low force sensors.)
We will also follow the recommendations listed in your report.

Attached are the pictures of the control cabinet.

Great. Please text me at 8588609985 when you get here.

I have the correct TD Tool and used it for the auto-calibration. Trying a Z height change. The other tool was longer so logically the correct tool will stop short.

Chris,

Thanks for sending those messages. I am back in the office today.

I think the TD pickup Z position for the chip is off because we were using a non-standard TD tool. The machine is programmed for the longer TD tool.

I am headed out to change this Z value slightly to see if it will change the Z position. If it does my plan is to reduce the Z height until it touches and picks up the chip.

Please let me know your ETA tomorrow. As Mike said, just bring an ID. I must escort you while you are here, but we will be in a regular production area.

Dave,

I sent you a text message to check if you can access an assistant to reteach the cavity position for the BMC chip. This should address the pick-up issue. The mental issue I am having is since we only replaced the bond head I am not sure why it would be off. Even if you get the machine running which is priority #1 I think we should still plan for me to come onsite to do a thorough PM and calibration so we have a known good status of the system.

If you can't get it up and running I can probably be onsite next Wednesday.

Hi Chris,

The issue is the BMC tool stops about 0.020” short of the glass chip. This is the step immediately after I auto cal uses the TD tool to touch off in the BMC and find the circular fiducials.

I tried it over and over, every time the BMC stops short and throws a vacuum sensing error because it thinks it is picking up the chip but is not.

Mike,

No worries. I just realized I typed up a reply to Dave last night in the text message but then got distracted and never hit send. The fact that it completes the first step with the touchdown tool and then fails the BMC pick-up is strange. Initially Dave didn't have the right Touchdown tool on hand and I can't remember if he did end up finding it. Can you confirm that the autocal is being performed with the below Touchdown tool and not the custom tool you use in production as TD tool.

Hi Chris –

Apologies for switching back over to e-mail (Dave informed me yesterday that you two were texting at this point), but Dave is out for a few days and I wanted to run a theory by you on the latest discovery on the machine. I’m assuming Dave let you know that he’s found the issue to be something to do with Z-axis. It’s not so much that the machine won’t pick up the chrome/glass chip due to vacuum (it will hold the part just fine if held directly to the nozzle, I’m told), but that the nozzle isn’t making contact with the chip.

The chip we are using is an older Besi PN, 04101310101. I’m told Besi has discontinued that part, with the new PN being 5001-9311. Long shot, but is there any chance there is a physical difference between the old and new part (thickness, maybe?) that could be contributing to this?

Sorry for the armchair QBing.

David,

Sounds like you either have a vacuum issue for the component vacuum through the bond head or the BMC tool has some damage on it not sealing the vacuum properly when picking the BMC chip from the cavity. The Tool and Component vacuum are two separate lines.

Did you inspect the BMC tool surface?

Hi Chris,

Yes, the chip is there. I see what you mean about it having fiducials printed on it so you would know it is there. The chip stuck to my finger so I could lift it off. It is installed properly.

Today is the same as last Thursday. Starting auto-calibration, manually adjusting to the chip fiducials works but the chip is not being picked up. Vacuum on the tip feels strong on the BMC tip but vacuum through the tip does not appear to be enough to lift the chip. I am looking for an air leak. FYI, this machine has a vacuum pump, it does not use the vacuum port on the back of the machine.

Thank you,

Dave

HI Mike,

To answer your questions yes that is the BMC Chip but from the pictures David sent I think you already have this part. When you look at this image in the email for the part what I was trying to point out is that this chip has fiducials on them and when you look closely you'll see that they are plated onto the glass chip on one side. When this chip is loaded into the cavity on the machine (between the bond force sensor and the mini-BMC plate) it needs to be inserted with the chrome fiducials facing down. (if it's loaded with the chrome facing up you'll get a parallax when the substrate camera performs measurements of the chip on the mini-BMC plate and it will also set the uplooking camera focus height incorrectly).

Hope this helps. You guys did great work on your own, you are almost there.

Hello Chris,

Your instruction, tool ID picture below and several hours of technical support today are very much appreciated. Thank you for the fantastic support!

You helped me complete all the BH calibration routines today requiring superuser access. The BH appears to be operating as it should be.

Unfortunately, I am still stuck on the last step of auto-calibration and know why. The chip you were telling me was to be picked up from the BMC and placed 10-20 times is not there. There is no one sided chrome piece and I do not recall it ever being there. I will ask our BWI operations if they can send us one. That is the very last step of calibration before testing the tool bank.

There was a glass slide over the force sensor but that shattered last year. I was advised it is not needed and have run force calibration since then with no issues. If I am mistaken and this is the piece you were talking about, please let me know and I can request it. The below statement from the machine basics manual and leads me to think it might be the glass slide I need.

Best regards,

Dave

Hi Chris,

Good afternoon. On Friday, I tried to fix the theta offset by changing the values but did not have luck. Even when I had the BH tip and PU tool aligned, pick up still failed.

This morning, I noticed the BH tip spins freely, but when I change the direction of rotation, I feel a spot of resistance that goes away after 1 turn. Change rotation direction again and same result. I am speculating the internal encoder came loose. That would also help explain why the theta would not initialize for several days then started “working” again.

We have a bond head arriving from BWI as early as tomorrow. I received confirmation on which controller to purchase. We may have found one available.

Do you have any availability to come here and install the BH and Controller for us? If yes, may we please have a quote?

Hi David,

Thanks for the break-down. It sounds like you have multiple things going on. It's probably easiest if we jump on a call tomorrow. I have a meeting from approx. 8am-9am PST but you can give me a call before or after that, just give me a heads-up. From reviewing the logfiles and your summary I am seeing this timeline of events. Let me know if this is incorrect. If the timeline is correct we should 'only' have to fix the 4deg offset and the tool detection?

Hi Chris,

Thank you offering to help with our machine woes. This has been an evolving issue since January 13^th.

System info:

MC4 Datacon 2200 evo Automatic Dispense and Component Placement System

SN: 9502610007253

Our machine uses System 2 only and a non-heated bond head with magazine fed waffle packs.

Log files from the beginning of the issue on 1/13 and as of last Friday 1/29 are attached. Nothing of note has changed since last Friday. The January superuser PW expired.

Symptoms:

1/13: Alarm 2.2609: Initialization failed, Axis MtPPThetaSys2 could not be initialized (IMG_4034.jpg). A warning preceded this alarm by a day or two.

This alarm state lasted several days, maybe a week. After manually spinning the bond head tip, running Theta Axis calibration, and running the initialization routine repeatedly, the 2.2609 alarm resolved itself and the machine would successfully initialize.

After the theta initialization alarm was resolved, the pickup tip was rotated off center about 4 degrees (picture attached). The PU tip is no longer aligned with the PP tool locating pins and cannot pick tools up. The machine provides a message to manually place the tip on the bond head. This worked until yesterday. Currently, the machine does not recognize a tip manually placed onto the bond head. Increased vacuum did not resolve the issue. I have verified the tip is firmly in place. Maybe it is the vacuum switch but odd it decided to fail now. There are no hose leaks I can see or hear. I need to trace this farther upstream.

Currently, I need February’s superuser PW so I can recalibrate the bond head tip back to zero degrees. A request for the PW was sent to Besi. I have the UC Calibration tool on hand for this. Once that is resolved, the issue of the PU tip not being recognized by the machine remains. I am cautiously optimistic this will resolve itself or a root cause will be found.

Lastly, it appears the air bearing in the bond head is good. I push it up and it goes down by itself, no sticking. IMG_4116 shows the TD sensor value.

Thank you again for your time on this. I really appreciate the support. I can provide more details as needed. I did not attach videos due to file size.

Hi Dave,

It was great meeting with you and the team last week.

Please find the attached service report summarizing my visit and the current status of the equipment. I have also attached a spreadsheet detailing the recommended spare parts we discussed. Please keep in mind that this list was not generated specifically from your machine’s serial number, so you will need to verify all part numbers for compatibility before finalizing any purchases.

Additionally, I recommend requesting quotes for the PC and the Image Processing Unit, as I did not include those specific items on the attached list.

Please let me know if you have any questions or need further clarification on the report or the recommended spares.

I have the correct TD Tool and used it for the auto-calibration. Trying a Z height change. The other tool was longer so logically the correct tool will stop short.

Chris,

Thanks for sending those messages. I am back in the office today.

I think the TD pickup Z position for the chip is off because we were using a non-standard TD tool. The machine is programmed for the longer TD tool.

I am headed out to change this Z value slightly to see if it will change the Z position. If it does my plan is to reduce the Z height until it touches and picks up the chip.

Please let me know your ETA tomorrow. As Mike said, just bring an ID. I must escort you while you are here, but we will be in a regular production area.

Dave,

I sent you a text message to check if you can access an assistant to reteach the cavity position for the BMC chip. This should address the pick-up issue. The mental issue I am having is since we only replaced the bond head I am not sure why it would be off. Even if you get the machine running which is priority #1 I think we should still plan for me to come onsite to do a thorough PM and calibration so we have a known good status of the system.

If you can't get it up and running I can probably be onsite next Wednesday.

The issue is the BMC tool stops about 0.020” short of the glass chip. This is the step immediately after I auto cal uses the TD tool to touch off in the BMC and find the circular fiducials.

I tried it over and over, every time the BMC stops short and throws a vacuum sensing error because it thinks it is picking up the chip but is not.

Thank you,

Dave

Hi Chris –

Admittedly, I’m not at all qualified to answer your question, though I’m certainly tracking the logic.

We’re at a critical point where it is imperative we get the machine back up and running ASAP. I know we have discussed the possibility of onsite support in the past. Is that still an option and, if so, could you provide an estimated date and a quote?

Many thanks!

Mike,

No worries. I just realized I typed up a reply to Dave last night in the text message but then got distracted and never hit send. The fact that it completes the first step with the touchdown tool and then fails the BMC pick-up is strange. Initially Dave didn't have the right Touchdown tool on hand and I can't remember if he did end up finding it. Can you confirm that the autocal is being performed with the below Touchdown tool and not the custom tool you use in production as TD tool.

Chris

Hi Chris –

Apologies for switching back over to e-mail (Dave informed me yesterday that you two were texting at this point), but Dave is out for a few days and I wanted to run a theory by you on the latest discovery on the machine. I’m assuming Dave let you know that he’s found the issue to be something to do with Z-axis. It’s not so much that the machine won’t pick up the chrome/glass chip due to vacuum (it will hold the part just fine if held directly to the nozzle, I’m told), but that the nozzle isn’t making contact with the chip.

The chip we are using is an older Besi PN, 04101310101. I’m told Besi has discontinued that part, with the new PN being 5001-9311. Long shot, but is there any chance there is a physical difference between the old and new part (thickness, maybe?) that could be contributing to this?

Sorry for the armchair QBing.

David,

Sounds like you either have a vacuum issue for the component vacuum through the bond head or the BMC tool has some damage on it not sealing the vacuum properly when picking the BMC chip from the cavity. The Tool and Component vacuum are two separate lines.

Did you inspect the BMC tool surface?

Chris

Hi Chris,

Yes, the chip is there. I see what you mean about it having fiducials printed on it so you would know it is there. The chip stuck to my finger so I could lift it off. It is installed properly.

Today is the same as last Thursday. Starting auto-calibration, manually adjusting to the chip fiducials works but the chip is not being picked up. Vacuum on the tip feels strong on the BMC tip but vacuum through the tip does not appear to be enough to lift the chip. I am looking for an air leak. FYI, this machine has a vacuum pump, it does not use the vacuum port on the back of the machine.

Thank you,

Dave

HI Mike,

To answer your questions yes that is the BMC Chip but from the pictures David sent I think you already have this part. When you look at this image in the email for the part what I was trying to point out is that this chip has fiducials on them and when you look closely you'll see that they are plated onto the glass chip on one side. When this chip is loaded into the cavity on the machine (between the bond force sensor and the mini-BMC plate) it needs to be inserted with the chrome fiducials facing down. (if it's loaded with the chrome facing up you'll get a parallax when the substrate camera performs measurements of the chip on the mini-BMC plate and it will also set the uplooking camera focus height incorrectly).

Hope this helps. You guys did great work on your own, you are almost there.

Hello Chris,

Your instruction, tool ID picture below and several hours of technical support today are very much appreciated. Thank you for the fantastic support!

You helped me complete all the BH calibration routines today requiring superuser access. The BH appears to be operating as it should be.

Unfortunately, I am still stuck on the last step of auto-calibration and know why. The chip you were telling me was to be picked up from the BMC and placed 10-20 times is not there. There is no one sided chrome piece and I do not recall it ever being there. I will ask our BWI operations if they can send us one. That is the very last step of calibration before testing the tool bank.

There was a glass slide over the force sensor but that shattered last year. I was advised it is not needed and have run force calibration since then with no issues. If I am mistaken and this is the piece you were talking about, please let me know and I can request it. The below statement from the machine basics manual and leads me to think it might be the glass slide I need.

Best regards,

Dave

Hi Chris,

Good afternoon. On Friday, I tried to fix the theta offset by changing the values but did not have luck. Even when I had the BH tip and PU tool aligned, pick up still failed.

This morning, I noticed the BH tip spins freely, but when I change the direction of rotation, I feel a spot of resistance that goes away after 1 turn. Change rotation direction again and same result. I am speculating the internal encoder came loose. That would also help explain why the theta would not initialize for several days then started “working” again.

We have a bond head arriving from BWI as early as tomorrow. I received confirmation on which controller to purchase. We may have found one available.

Do you have any availability to come here and install the BH and Controller for us? If yes, may we please have a quote?

Hi David,

Thanks for the break-down. It sounds like you have multiple things going on. It's probably easiest if we jump on a call tomorrow. I have a meeting from approx. 8am-9am PST but you can give me a call before or after that, just give me a heads-up. From reviewing the logfiles and your summary I am seeing this timeline of events. Let me know if this is incorrect. If the timeline is correct we should 'only' have to fix the 4deg offset and the tool detection?

Time

Event

~Jan 11

Warning precedes the alarm (customer report)

Jan 13 09:51

First theta homing failure — tracking error + current limit

Jan 13 11:16

Shifts to Error 62 (index pulse not found), Alarm 2.2609

Jan 13 15:16-15:20

Jan 29 13:43

Additional Z-axis position loss (This was odd. I was working with our technician to run the machine for solder dispense only, but a Z-axis alarm appeared. Recalibration of the Z-axis resolved the issue and it has yet to reappear. I took it as a symptom of the larger issue we are trying to get to the root of).

Jan 29 14:07-14:11

Tool vacuum check fails repeatedly (75-78, threshold 25-50) (This is the current state. It was OK earlier this week.)

Thank you, Jim!

Hi Chris,

Thank you offering to help with our machine woes. This has been an evolving issue since January 13^th.

System info:

MC4 Datacon 2200 evo Automatic Dispense and Component Placement System

SN: 9502610007253

Our machine uses System 2 only and a non-heated bond head with magazine fed waffle packs.

Log files from the beginning of the issue on 1/13 and as of last Friday 1/29 are attached. Nothing of note has changed since last Friday. The January superuser PW expired.

Symptoms:

1/13: Alarm 2.2609: Initialization failed, Axis MtPPThetaSys2 could not be initialized (IMG_4034.jpg). A warning preceded this alarm by a day or two.

This alarm state lasted several days, maybe a week. After manually spinning the bond head tip, running Theta Axis calibration, and running the initialization routine repeatedly, the 2.2609 alarm resolved itself and the machine would successfully initialize.

After the theta initialization alarm was resolved, the pickup tip was rotated off center about 4 degrees (picture attached). The PU tip is no longer aligned with the PP tool locating pins and cannot pick tools up. The machine provides a message to manually place the tip on the bond head. This worked until yesterday. Currently, the machine does not recognize a tip manually placed onto the bond head. Increased vacuum did not resolve the issue. I have verified the tip is firmly in place. Maybe it is the vacuum switch but odd it decided to fail now. There are no hose leaks I can see or hear. I need to trace this farther upstream.

Currently, I need February’s superuser PW so I can recalibrate the bond head tip back to zero degrees. A request for the PW was sent to Besi. I have the UC Calibration tool on hand for this. Once that is resolved, the issue of the PU tip not being recognized by the machine remains. I am cautiously optimistic this will resolve itself or a root cause will be found.

Lastly, it appears the air bearing in the bond head is good. I push it up and it goes down by itself, no sticking. IMG_4116 shows the TD sensor value.

Thank you again for your time on this. I really appreciate the support. I can provide more details as needed. I did not attach videos due to file size.

Please find the attached service report summarizing my visit and the current status of the equipment. I have also attached a spreadsheet detailing the recommended spare parts we discussed. Please keep in mind that this list was not generated specifically from your machine’s serial number, so you will need to verify all part numbers for compatibility before finalizing any purchases.

Great. Please text me at 8588609985 when you get here.

I have the correct TD Tool and used it for the auto-calibration. Trying a Z height change. The other tool was longer so logically the correct tool will stop short.

Hi David, Mike,

I'll be there tomorrow between 8:00-8:30am.

Regarding the TD tool, I thought you located the correct one? If you didn't find it, please let me know; otherwise, I'll have to figure something out.

Chris,

Thanks for sending those messages. I am back in the office today.

I think the TD pickup Z position for the chip is off because we were using a non-standard TD tool. The machine is programmed for the longer TD tool.

I am headed out to change this Z value slightly to see if it will change the Z position. If it does my plan is to reduce the Z height until it touches and picks up the chip.

Please let me know your ETA tomorrow. As Mike said, just bring an ID. I must escort you while you are here, but we will be in a regular production area.

Thank you,

Dave

Dave,

I sent you a text message to check if you can access an assistant to reteach the cavity position for the BMC chip. This should address the pick-up issue. The mental issue I am having is since we only replaced the bond head I am not sure why it would be off. Even if you get the machine running which is priority #1 I think we should still plan for me to come onsite to do a thorough PM and calibration so we have a known good status of the system.

If you can't get it up and running I can probably be onsite next Wednesday.

Hi Chris,

The issue is the BMC tool stops about 0.020” short of the glass chip. This is the step immediately after I auto cal uses the TD tool to touch off in the BMC and find the circular fiducials.

I tried it over and over, every time the BMC stops short and throws a vacuum sensing error because it thinks it is picking up the chip but is not.

Thank you,

Dave

Hi Chris –

Admittedly, I’m not at all qualified to answer your question, though I’m certainly tracking the logic.

We’re at a critical point where it is imperative we get the machine back up and running ASAP. I know we have discussed the possibility of onsite support in the past. Is that still an option and, if so, could you provide an estimated date and a quote?

Many thanks!

Mike,

No worries. I just realized I typed up a reply to Dave last night in the text message but then got distracted and never hit send. The fact that it completes the first step with the touchdown tool and then fails the BMC pick-up is strange. Initially Dave didn't have the right Touchdown tool on hand and I can't remember if he did end up finding it. Can you confirm that the autocal is being performed with the below Touchdown tool and not the custom tool you use in production as TD tool.

Chris

Hi Chris –

Apologies for switching back over to e-mail (Dave informed me yesterday that you two were texting at this point), but Dave is out for a few days and I wanted to run a theory by you on the latest discovery on the machine. I’m assuming Dave let you know that he’s found the issue to be something to do with Z-axis. It’s not so much that the machine won’t pick up the chrome/glass chip due to vacuum (it will hold the part just fine if held directly to the nozzle, I’m told), but that the nozzle isn’t making contact with the chip.

The chip we are using is an older Besi PN, 04101310101. I’m told Besi has discontinued that part, with the new PN being 5001-9311. Long shot, but is there any chance there is a physical difference between the old and new part (thickness, maybe?) that could be contributing to this?

Sorry for the armchair QBing.

David,

Sounds like you either have a vacuum issue for the component vacuum through the bond head or the BMC tool has some damage on it not sealing the vacuum properly when picking the BMC chip from the cavity. The Tool and Component vacuum are two separate lines.

Did you inspect the BMC tool surface?

Chris

Hi Chris,

Yes, the chip is there. I see what you mean about it having fiducials printed on it so you would know it is there. The chip stuck to my finger so I could lift it off. It is installed properly.

Today is the same as last Thursday. Starting auto-calibration, manually adjusting to the chip fiducials works but the chip is not being picked up. Vacuum on the tip feels strong on the BMC tip but vacuum through the tip does not appear to be enough to lift the chip. I am looking for an air leak. FYI, this machine has a vacuum pump, it does not use the vacuum port on the back of the machine.

Thank you,

HI Mike,

To answer your questions yes that is the BMC Chip but from the pictures David sent I think you already have this part. When you look at this image in the email for the part what I was trying to point out is that this chip has fiducials on them and when you look closely you'll see that they are plated onto the glass chip on one side. When this chip is loaded into the cavity on the machine (between the bond force sensor and the mini-BMC plate) it needs to be inserted with the chrome fiducials facing down. (if it's loaded with the chrome facing up you'll get a parallax when the substrate camera performs measurements of the chip on the mini-BMC plate and it will also set the uplooking camera focus height incorrectly).

Hope this helps. You guys did great work on your own, you are almost there.

Hello Chris,

Your instruction, tool ID picture below and several hours of technical support today are very much appreciated. Thank you for the fantastic support!

You helped me complete all the BH calibration routines today requiring superuser access. The BH appears to be operating as it should be.

Unfortunately, I am still stuck on the last step of auto-calibration and know why. The chip you were telling me was to be picked up from the BMC and placed 10-20 times is not there. There is no one sided chrome piece and I do not recall it ever being there. I will ask our BWI operations if they can send us one. That is the very last step of calibration before testing the tool bank.

There was a glass slide over the force sensor but that shattered last year. I was advised it is not needed and have run force calibration since then with no issues. If I am mistaken and this is the piece you were talking about, please let me know and I can request it. The below statement from the machine basics manual and leads me to think it might be the glass slide I need.

Best regards,

Dave

Hi Chris,

Good afternoon. On Friday, I tried to fix the theta offset by changing the values but did not have luck. Even when I had the BH tip and PU tool aligned, pick up still failed.

This morning, I noticed the BH tip spins freely, but when I change the direction of rotation, I feel a spot of resistance that goes away after 1 turn. Change rotation direction again and same result. I am speculating the internal encoder came loose. That would also help explain why the theta would not initialize for several days then started “working” again.

We have a bond head arriving from BWI as early as tomorrow. I received confirmation on which controller to purchase. We may have found one available.

Do you have any availability to come here and install the BH and Controller for us? If yes, may we please have a quote?

Hi David,

Thanks for the break-down. It sounds like you have multiple things going on. It's probably easiest if we jump on a call tomorrow. I have a meeting from approx. 8am-9am PST but you can give me a call before or after that, just give me a heads-up. From reviewing the logfiles and your summary I am seeing this timeline of events. Let me know if this is incorrect. If the timeline is correct we should 'only' have to fix the 4deg offset and the tool detection?

Hi Chris,

Thank you offering to help with our machine woes. This has been an evolving issue since January 13^th.

System info:

MC4 Datacon 2200 evo Automatic Dispense and Component Placement System

SN: 9502610007253

Our machine uses System 2 only and a non-heated bond head with magazine fed waffle packs.

Log files from the beginning of the issue on 1/13 and as of last Friday 1/29 are attached. Nothing of note has changed since last Friday. The January superuser PW expired.

Symptoms:

1/13: Alarm 2.2609: Initialization failed, Axis MtPPThetaSys2 could not be initialized (IMG_4034.jpg). A warning preceded this alarm by a day or two.

This alarm state lasted several days, maybe a week. After manually spinning the bond head tip, running Theta Axis calibration, and running the initialization routine repeatedly, the 2.2609 alarm resolved itself and the machine would successfully initialize.

After the theta initialization alarm was resolved, the pickup tip was rotated off center about 4 degrees (picture attached). The PU tip is no longer aligned with the PP tool locating pins and cannot pick tools up. The machine provides a message to manually place the tip on the bond head. This worked until yesterday. Currently, the machine does not recognize a tip manually placed onto the bond head. Increased vacuum did not resolve the issue. I have verified the tip is firmly in place. Maybe it is the vacuum switch but odd it decided to fail now. There are no hose leaks I can see or hear. I need to trace this farther upstream.

Currently, I need February’s superuser PW so I can recalibrate the bond head tip back to zero degrees. A request for the PW was sent to Besi. I have the UC Calibration tool on hand for this. Once that is resolved, the issue of the PU tip not being recognized by the machine remains. I am cautiously optimistic this will resolve itself or a root cause will be found.

Lastly, it appears the air bearing in the bond head is good. I push it up and it goes down by itself, no sticking. IMG_4116 shows the TD sensor value.

Thank you again for your time on this. I really appreciate the support. I can provide more details as needed. I did not attach videos due to file size.

Morning Chris –

Some quick directions since coming to our campus for the first time can be a little confusing…. Once you turn onto Innovation Dr from Rancho Carmel Dr, continue through the first light (Scripps Driveway) and follow the road around the bend until you see the main entrance for Northrop Grumman on the LH side. From there, go past the guard tower (will not be manned) and follow signs for visitor parking. Walk into the main entrance, behind the flagpole / turnaround. If you let the security guard know you’re there for David Kellogg, they’ll begin processing your badge and contact Dave.

Thanks!

Auto-calibration is complete. I need to adjust Theta zero position to match the tools’ locating pins. Then a full system backup and we will see if we have issues with production.

Hi Chris,

Great. Please text me at 8588609985 when you get here.

I have the correct TD Tool and used it for the auto-calibration. Trying a Z height change. The other tool was longer so logically the correct tool will stop short.

Hi David, Mike,

I'll be there tomorrow between 8:00-8:30am.

Regarding the TD tool, I thought you located the correct one? If you didn't find it, please let me know; otherwise, I'll have to figure something out.

Chris,

Thanks for sending those messages. I am back in the office today.

I think the TD pickup Z position for the chip is off because we were using a non-standard TD tool. The machine is programmed for the longer TD tool.

I am headed out to change this Z value slightly to see if it will change the Z position. If it does my plan is to reduce the Z height until it touches and picks up the chip.

Please let me know your ETA tomorrow. As Mike said, just bring an ID. I must escort you while you are here, but we will be in a regular production area.

Thank you,

Dave,

I sent you a text message to check if you can access an assistant to reteach the cavity position for the BMC chip. This should address the pick-up issue. The mental issue I am having is since we only replaced the bond head I am not sure why it would be off. Even if you get the machine running which is priority #1 I think we should still plan for me to come onsite to do a thorough PM and calibration so we have a known good status of the system.

If you can't get it up and running I can probably be onsite next Wednesday.

Hi Chris,

The issue is the BMC tool stops about 0.020” short of the glass chip. This is the step immediately after I auto cal uses the TD tool to touch off in the BMC and find the circular fiducials.

I tried it over and over, every time the BMC stops short and throws a vacuum sensing error because it thinks it is picking up the chip but is not.

Hi Chris –

Admittedly, I’m not at all qualified to answer your question, though I’m certainly tracking the logic.

We’re at a critical point where it is imperative we get the machine back up and running ASAP. I know we have discussed the possibility of onsite support in the past. Is that still an option and, if so, could you provide an estimated date and a quote?

Many thanks!

Mike,

No worries. I just realized I typed up a reply to Dave last night in the text message but then got distracted and never hit send. The fact that it completes the first step with the touchdown tool and then fails the BMC pick-up is strange. Initially Dave didn't have the right Touchdown tool on hand and I can't remember if he did end up finding it. Can you confirm that the autocal is being performed with the below Touchdown tool and not the custom tool you use in production as TD tool.

Chris

Hi Chris –

Apologies for switching back over to e-mail (Dave informed me yesterday that you two were texting at this point), but Dave is out for a few days and I wanted to run a theory by you on the latest discovery on the machine. I’m assuming Dave let you know that he’s found the issue to be something to do with Z-axis. It’s not so much that the machine won’t pick up the chrome/glass chip due to vacuum (it will hold the part just fine if held directly to the nozzle, I’m told), but that the nozzle isn’t making contact with the chip.

The chip we are using is an older Besi PN, 04101310101. I’m told Besi has discontinued that part, with the new PN being 5001-9311. Long shot, but is there any chance there is a physical difference between the old and new part (thickness, maybe?) that could be contributing to this?

Sorry for the armchair QBing.

David,

Sounds like you either have a vacuum issue for the component vacuum through the bond head or the BMC tool has some damage on it not sealing the vacuum properly when picking the BMC chip from the cavity. The Tool and Component vacuum are two separate lines.

Did you inspect the BMC tool surface?

Chris

Hi Chris,

Yes, the chip is there. I see what you mean about it having fiducials printed on it so you would know it is there. The chip stuck to my finger so I could lift it off. It is installed properly.

Today is the same as last Thursday. Starting auto-calibration, manually adjusting to the chip fiducials works but the chip is not being picked up. Vacuum on the tip feels strong on the BMC tip but vacuum through the tip does not appear to be enough to lift the chip. I am looking for an air leak. FYI, this machine has a vacuum pump, it does not use the vacuum port on the back of the machine.

Thank you,

HI Mike,

To answer your questions yes that is the BMC Chip but from the pictures David sent I think you already have this part. When you look at this image in the email for the part what I was trying to point out is that this chip has fiducials on them and when you look closely you'll see that they are plated onto the glass chip on one side. When this chip is loaded into the cavity on the machine (between the bond force sensor and the mini-BMC plate) it needs to be inserted with the chrome fiducials facing down. (if it's loaded with the chrome facing up you'll get a parallax when the substrate camera performs measurements of the chip on the mini-BMC plate and it will also set the uplooking camera focus height incorrectly).

Hope this helps. You guys did great work on your own, you are almost there.

Hello Chris,

Your instruction, tool ID picture below and several hours of technical support today are very much appreciated. Thank you for the fantastic support!

You helped me complete all the BH calibration routines today requiring superuser access. The BH appears to be operating as it should be.

Unfortunately, I am still stuck on the last step of auto-calibration and know why. The chip you were telling me was to be picked up from the BMC and placed 10-20 times is not there. There is no one sided chrome piece and I do not recall it ever being there. I will ask our BWI operations if they can send us one. That is the very last step of calibration before testing the tool bank.

There was a glass slide over the force sensor but that shattered last year. I was advised it is not needed and have run force calibration since then with no issues. If I am mistaken and this is the piece you were talking about, please let me know and I can request it. The below statement from the machine basics manual and leads me to think it might be the glass slide I need.

Best regards,

Dave

Hi Chris,

Good afternoon. On Friday, I tried to fix the theta offset by changing the values but did not have luck. Even when I had the BH tip and PU tool aligned, pick up still failed.

This morning, I noticed the BH tip spins freely, but when I change the direction of rotation, I feel a spot of resistance that goes away after 1 turn. Change rotation direction again and same result. I am speculating the internal encoder came loose. That would also help explain why the theta would not initialize for several days then started “working” again.

We have a bond head arriving from BWI as early as tomorrow. I received confirmation on which controller to purchase. We may have found one available.

Do you have any availability to come here and install the BH and Controller for us? If yes, may we please have a quote?

Hi David,

Thanks for the break-down. It sounds like you have multiple things going on. It's probably easiest if we jump on a call tomorrow. I have a meeting from approx. 8am-9am PST but you can give me a call before or after that, just give me a heads-up. From reviewing the logfiles and your summary I am seeing this timeline of events. Let me know if this is incorrect. If the timeline is correct we should 'only' have to fix the 4deg offset and the tool detection?

Hi Chris,

Thank you offering to help with our machine woes. This has been an evolving issue since January 13^th.

System info:

MC4 Datacon 2200 evo Automatic Dispense and Component Placement System

SN: 9502610007253

Our machine uses System 2 only and a non-heated bond head with magazine fed waffle packs.

Log files from the beginning of the issue on 1/13 and as of last Friday 1/29 are attached. Nothing of note has changed since last Friday. The January superuser PW expired.

Symptoms:

1/13: Alarm 2.2609: Initialization failed, Axis MtPPThetaSys2 could not be initialized (IMG_4034.jpg). A warning preceded this alarm by a day or two.

This alarm state lasted several days, maybe a week. After manually spinning the bond head tip, running Theta Axis calibration, and running the initialization routine repeatedly, the 2.2609 alarm resolved itself and the machine would successfully initialize.

After the theta initialization alarm was resolved, the pickup tip was rotated off center about 4 degrees (picture attached). The PU tip is no longer aligned with the PP tool locating pins and cannot pick tools up. The machine provides a message to manually place the tip on the bond head. This worked until yesterday. Currently, the machine does not recognize a tip manually placed onto the bond head. Increased vacuum did not resolve the issue. I have verified the tip is firmly in place. Maybe it is the vacuum switch but odd it decided to fail now. There are no hose leaks I can see or hear. I need to trace this farther upstream.

Currently, I need February’s superuser PW so I can recalibrate the bond head tip back to zero degrees. A request for the PW was sent to Besi. I have the UC Calibration tool on hand for this. Once that is resolved, the issue of the PU tip not being recognized by the machine remains. I am cautiously optimistic this will resolve itself or a root cause will be found.

Lastly, it appears the air bearing in the bond head is good. I push it up and it goes down by itself, no sticking. IMG_4116 shows the TD sensor value.

Thank you again for your time on this. I really appreciate the support. I can provide more details as needed. I did not attach videos due to file size.

Hi Chris –

Admittedly, I’m not at all qualified to answer your question, though I’m certainly tracking the logic.

We’re at a critical point where it is imperative we get the machine back up and running ASAP. I know we have discussed the possibility of onsite support in the past. Is that still an option and, if so, could you provide an estimated date and a quote?

Many thanks!

Mike,

No worries. I just realized I typed up a reply to Dave last night in the text message but then got distracted and never hit send. The fact that it completes the first step with the touchdown tool and then fails the BMC pick-up is strange. Initially Dave didn't have the right Touchdown tool on hand and I can't remember if he did end up finding it. Can you confirm that the autocal is being performed with the below Touchdown tool and not the custom tool you use in production as TD tool.

Hi Chris –

Apologies for switching back over to e-mail (Dave informed me yesterday that you two were texting at this point), but Dave is out for a few days and I wanted to run a theory by you on the latest discovery on the machine. I’m assuming Dave let you know that he’s found the issue to be something to do with Z-axis. It’s not so much that the machine won’t pick up the chrome/glass chip due to vacuum (it will hold the part just fine if held directly to the nozzle, I’m told), but that the nozzle isn’t making contact with the chip.

The chip we are using is an older Besi PN, 04101310101. I’m told Besi has discontinued that part, with the new PN being 5001-9311. Long shot, but is there any chance there is a physical difference between the old and new part (thickness, maybe?) that could be contributing to this?

Sorry for the armchair QBing.

David,

Sounds like you either have a vacuum issue for the component vacuum through the bond head or the BMC tool has some damage on it not sealing the vacuum properly when picking the BMC chip from the cavity. The Tool and Component vacuum are two separate lines.

Did you inspect the BMC tool surface?

Hi Chris,

Yes, the chip is there. I see what you mean about it having fiducials printed on it so you would know it is there. The chip stuck to my finger so I could lift it off. It is installed properly.

Today is the same as last Thursday. Starting auto-calibration, manually adjusting to the chip fiducials works but the chip is not being picked up. Vacuum on the tip feels strong on the BMC tip but vacuum through the tip does not appear to be enough to lift the chip. I am looking for an air leak. FYI, this machine has a vacuum pump, it does not use the vacuum port on the back of the machine.

Thank you,

Dave

HI Mike,

To answer your questions yes that is the BMC Chip but from the pictures David sent I think you already have this part. When you look at this image in the email for the part what I was trying to point out is that this chip has fiducials on them and when you look closely you'll see that they are plated onto the glass chip on one side. When this chip is loaded into the cavity on the machine (between the bond force sensor and the mini-BMC plate) it needs to be inserted with the chrome fiducials facing down. (if it's loaded with the chrome facing up you'll get a parallax when the substrate camera performs measurements of the chip on the mini-BMC plate and it will also set the uplooking camera focus height incorrectly).

Hope this helps. You guys did great work on your own, you are almost there.

Hello Chris,

Your instruction, tool ID picture below and several hours of technical support today are very much appreciated. Thank you for the fantastic support!

You helped me complete all the BH calibration routines today requiring superuser access. The BH appears to be operating as it should be.

Unfortunately, I am still stuck on the last step of auto-calibration and know why. The chip you were telling me was to be picked up from the BMC and placed 10-20 times is not there. There is no one sided chrome piece and I do not recall it ever being there. I will ask our BWI operations if they can send us one. That is the very last step of calibration before testing the tool bank.

There was a glass slide over the force sensor but that shattered last year. I was advised it is not needed and have run force calibration since then with no issues. If I am mistaken and this is the piece you were talking about, please let me know and I can request it. The below statement from the machine basics manual and leads me to think it might be the glass slide I need.

Best regards,

Dave

Hi Chris,

Good afternoon. On Friday, I tried to fix the theta offset by changing the values but did not have luck. Even when I had the BH tip and PU tool aligned, pick up still failed.

This morning, I noticed the BH tip spins freely, but when I change the direction of rotation, I feel a spot of resistance that goes away after 1 turn. Change rotation direction again and same result. I am speculating the internal encoder came loose. That would also help explain why the theta would not initialize for several days then started “working” again.

We have a bond head arriving from BWI as early as tomorrow. I received confirmation on which controller to purchase. We may have found one available.

Do you have any availability to come here and install the BH and Controller for us? If yes, may we please have a quote?

Hi Chris,

It was great to speak with you and thanks for the troubleshooting advice and support. For the tip vacuum issue, please note our machine is not hooked up to a vacuum line, our machine uses a venturi to generate the vacuum. I am headed to the machine to look for the module and check it, and fix the theta offset.

Hi David,

Thanks for the break-down. It sounds like you have multiple things going on. It's probably easiest if we jump on a call tomorrow. I have a meeting from approx. 8am-9am PST but you can give me a call before or after that, just give me a heads-up. From reviewing the logfiles and your summary I am seeing this timeline of events. Let me know if this is incorrect. If the timeline is correct we should 'only' have to fix the 4deg offset and the tool detection?

Time

Event

~Jan 11

Warning precedes the alarm (customer report)

Jan 13 09:51

First theta homing failure — tracking error + current limit

Jan 13 11:16

Shifts to Error 62 (index pulse not found), Alarm 2.2609

Jan 13 15:16-15:20

Multiple init attempts, all fail with Error 62

Jan 13–~Jan 20

Alarm state persists for ~1 week

~Jan 20

Manual spinning + repeated calibration resolves 2.2609

~Jan 20 onward

Theta homed but ~4° off center

Jan 29 12:23

Air pressure alarms appear (Error 2.501) (This was purposeful. I disconnected the vacuum line to the bond tip to check vacuum was strong. We have had zero air pressure alarms otherwise.)

Jan 29 13:43

Additional Z-axis position loss (This was odd. I was working with our technician to run the machine for solder dispense only, but a Z-axis alarm appeared. Recalibration of the Z-axis resolved the issue and it has yet to reappear. I took it as a symptom of the larger issue we are trying to get to the root of).

Jan 29 14:07-14:11

Tool vacuum check fails repeatedly (75-78, threshold 25-50) (This is the current state. It was OK earlier this week.)

Jan 29 14:34-15:06

Autocalibration fails — can't detect touchdown tool (Missing the PU tool due to the theta axis being off center.)

Jan 29 15:25

Bond force calibration fails

Jan 29 15:27-15:45

Continued tool detection failures during production attempts

Thank you, Jim!

Hi Chris,

Thank you offering to help with our machine woes. This has been an evolving issue since January 13^th.

System info:

MC4 Datacon 2200 evo Automatic Dispense and Component Placement System

SN: 9502610007253

Our machine uses System 2 only and a non-heated bond head with magazine fed waffle packs.

Log files from the beginning of the issue on 1/13 and as of last Friday 1/29 are attached. Nothing of note has changed since last Friday. The January superuser PW expired.

Symptoms:

1/13: Alarm 2.2609: Initialization failed, Axis MtPPThetaSys2 could not be initialized (IMG_4034.jpg). A warning preceded this alarm by a day or two.

This alarm state lasted several days, maybe a week. After manually spinning the bond head tip, running Theta Axis calibration, and running the initialization routine repeatedly, the 2.2609 alarm resolved itself and the machine would successfully initialize.

After the theta initialization alarm was resolved, the pickup tip was rotated off center about 4 degrees (picture attached). The PU tip is no longer aligned with the PP tool locating pins and cannot pick tools up. The machine provides a message to manually place the tip on the bond head. This worked until yesterday. Currently, the machine does not recognize a tip manually placed onto the bond head. Increased vacuum did not resolve the issue. I have verified the tip is firmly in place. Maybe it is the vacuum switch but odd it decided to fail now. There are no hose leaks I can see or hear. I need to trace this farther upstream.

Currently, I need February’s superuser PW so I can recalibrate the bond head tip back to zero degrees. A request for the PW was sent to Besi. I have the UC Calibration tool on hand for this. Once that is resolved, the issue of the PU tip not being recognized by the machine remains. I am cautiously optimistic this will resolve itself or a root cause will be found.

Lastly, it appears the air bearing in the bond head is good. I push it up and it goes down by itself, no sticking. IMG_4116 shows the TD sensor value.

Thank you again for your time on this. I really appreciate the support. I can provide more details as needed. I did not attach videos due to file size.

Dave,

I sent you a text message to check if you can access an assistant to reteach the cavity position for the BMC chip. This should address the pick-up issue. The mental issue I am having is since we only replaced the bond head I am not sure why it would be off. Even if you get the machine running which is priority #1 I think we should still plan for me to come onsite to do a thorough PM and calibration so we have a known good status of the system.

If you can't get it up and running I can probably be onsite next Wednesday.

Hi Chris,

The issue is the BMC tool stops about 0.020” short of the glass chip. This is the step immediately after I auto cal uses the TD tool to touch off in the BMC and find the circular fiducials.

I tried it over and over, every time the BMC stops short and throws a vacuum sensing error because it thinks it is picking up the chip but is not.

HI Mike,

To answer your questions yes that is the BMC Chip but from the pictures David sent I think you already have this part. When you look at this image in the email for the part what I was trying to point out is that this chip has fiducials on them and when you look closely you'll see that they are plated onto the glass chip on one side. When this chip is loaded into the cavity on the machine (between the bond force sensor and the mini-BMC plate) it needs to be inserted with the chrome fiducials facing down. (if it's loaded with the chrome facing up you'll get a parallax when the substrate camera performs measurements of the chip on the mini-BMC plate and it will also set the uplooking camera focus height incorrectly).

Hope this helps. You guys did great work on your own, you are almost there.

Hello Chris,

Your instruction, tool ID picture below and several hours of technical support today are very much appreciated. Thank you for the fantastic support!

You helped me complete all the BH calibration routines today requiring superuser access. The BH appears to be operating as it should be.

Unfortunately, I am still stuck on the last step of auto-calibration and know why. The chip you were telling me was to be picked up from the BMC and placed 10-20 times is not there. There is no one sided chrome piece and I do not recall it ever being there. I will ask our BWI operations if they can send us one. That is the very last step of calibration before testing the tool bank.

There was a glass slide over the force sensor but that shattered last year. I was advised it is not needed and have run force calibration since then with no issues. If I am mistaken and this is the piece you were talking about, please let me know and I can request it. The below statement from the machine basics manual and leads me to think it might be the glass slide I need.

Best regards,

Dave

Hi Chris,

Good afternoon. On Friday, I tried to fix the theta offset by changing the values but did not have luck. Even when I had the BH tip and PU tool aligned, pick up still failed.

This morning, I noticed the BH tip spins freely, but when I change the direction of rotation, I feel a spot of resistance that goes away after 1 turn. Change rotation direction again and same result. I am speculating the internal encoder came loose. That would also help explain why the theta would not initialize for several days then started “working” again.

We have a bond head arriving from BWI as early as tomorrow. I received confirmation on which controller to purchase. We may have found one available.

Do you have any availability to come here and install the BH and Controller for us? If yes, may we please have a quote?

Hi Chris,

It was great to speak with you and thanks for the troubleshooting advice and support. For the tip vacuum issue, please note our machine is not hooked up to a vacuum line, our machine uses a venturi to generate the vacuum. I am headed to the machine to look for the module and check it, and fix the theta offset.

Hi David,

Thanks for the break-down. It sounds like you have multiple things going on. It's probably easiest if we jump on a call tomorrow. I have a meeting from approx. 8am-9am PST but you can give me a call before or after that, just give me a heads-up. From reviewing the logfiles and your summary I am seeing this timeline of events. Let me know if this is incorrect. If the timeline is correct we should 'only' have to fix the 4deg offset and the tool detection?

Time

Event

~Jan 11

Warning precedes the alarm (customer report)

Jan 13 09:51

First theta homing failure — tracking error + current limit

Jan 13 11:16

Additional Z-axis position loss (This was odd. I was working with our technician to run the machine for solder dispense only, but a Z-axis alarm appeared. Recalibration of the Z-axis resolved the issue and it has yet to reappear. I took it as a symptom of the larger issue we are trying to get to the root of).

Jan 29 14:07-14:11

Tool vacuum check fails repeatedly (75-78, threshold 25-50) (This is the current state. It was OK earlier this week.)

Thank you, Jim!

Hi Chris,

Thank you offering to help with our machine woes. This has been an evolving issue since January 13^th.

System info:

MC4 Datacon 2200 evo Automatic Dispense and Component Placement System

SN: 9502610007253

Our machine uses System 2 only and a non-heated bond head with magazine fed waffle packs.

Log files from the beginning of the issue on 1/13 and as of last Friday 1/29 are attached. Nothing of note has changed since last Friday. The January superuser PW expired.

Symptoms:

1/13: Alarm 2.2609: Initialization failed, Axis MtPPThetaSys2 could not be initialized (IMG_4034.jpg). A warning preceded this alarm by a day or two.

This alarm state lasted several days, maybe a week. After manually spinning the bond head tip, running Theta Axis calibration, and running the initialization routine repeatedly, the 2.2609 alarm resolved itself and the machine would successfully initialize.

After the theta initialization alarm was resolved, the pickup tip was rotated off center about 4 degrees (picture attached). The PU tip is no longer aligned with the PP tool locating pins and cannot pick tools up. The machine provides a message to manually place the tip on the bond head. This worked until yesterday. Currently, the machine does not recognize a tip manually placed onto the bond head. Increased vacuum did not resolve the issue. I have verified the tip is firmly in place. Maybe it is the vacuum switch but odd it decided to fail now. There are no hose leaks I can see or hear. I need to trace this farther upstream.

Currently, I need February’s superuser PW so I can recalibrate the bond head tip back to zero degrees. A request for the PW was sent to Besi. I have the UC Calibration tool on hand for this. Once that is resolved, the issue of the PU tip not being recognized by the machine remains. I am cautiously optimistic this will resolve itself or a root cause will be found.

Lastly, it appears the air bearing in the bond head is good. I push it up and it goes down by itself, no sticking. IMG_4116 shows the TD sensor value.

Thank you again for your time on this. I really appreciate the support. I can provide more details as needed. I did not attach videos due to file size.

Dave,

I sent you a text message to check if you can access an assistant to reteach the cavity position for the BMC chip. This should address the pick-up issue. The mental issue I am having is since we only replaced the bond head I am not sure why it would be off. Even if you get the machine running which is priority #1 I think we should still plan for me to come onsite to do a thorough PM and calibration so we have a known good status of the system.

If you can't get it up and running I can probably be onsite next Wednesday.

Hi Chris,

The issue is the BMC tool stops about 0.020” short of the glass chip. This is the step immediately after I auto cal uses the TD tool to touch off in the BMC and find the circular fiducials.

I tried it over and over, every time the BMC stops short and throws a vacuum sensing error because it thinks it is picking up the chip but is not.

Thank you,

Mike,

No worries. I just realized I typed up a reply to Dave last night in the text message but then got distracted and never hit send. The fact that it completes the first step with the touchdown tool and then fails the BMC pick-up is strange. Initially Dave didn't have the right Touchdown tool on hand and I can't remember if he did end up finding it. Can you confirm that the autocal is being performed with the below Touchdown tool and not the custom tool you use in production as TD tool.

Hi Chris –

Apologies for switching back over to e-mail (Dave informed me yesterday that you two were texting at this point), but Dave is out for a few days and I wanted to run a theory by you on the latest discovery on the machine. I’m assuming Dave let you know that he’s found the issue to be something to do with Z-axis. It’s not so much that the machine won’t pick up the chrome/glass chip due to vacuum (it will hold the part just fine if held directly to the nozzle, I’m told), but that the nozzle isn’t making contact with the chip.

The chip we are using is an older Besi PN, 04101310101. I’m told Besi has discontinued that part, with the new PN being 5001-9311. Long shot, but is there any chance there is a physical difference between the old and new part (thickness, maybe?) that could be contributing to this?

Sorry for the armchair QBing.

David,

Sounds like you either have a vacuum issue for the component vacuum through the bond head or the BMC tool has some damage on it not sealing the vacuum properly when picking the BMC chip from the cavity. The Tool and Component vacuum are two separate lines.

Did you inspect the BMC tool surface?

Chris

Hi Chris,

Yes, the chip is there. I see what you mean about it having fiducials printed on it so you would know it is there. The chip stuck to my finger so I could lift it off. It is installed properly.

Today is the same as last Thursday. Starting auto-calibration, manually adjusting to the chip fiducials works but the chip is not being picked up. Vacuum on the tip feels strong on the BMC tip but vacuum through the tip does not appear to be enough to lift the chip. I am looking for an air leak. FYI, this machine has a vacuum pump, it does not use the vacuum port on the back of the machine.

HI Mike,

To answer your questions yes that is the BMC Chip but from the pictures David sent I think you already have this part. When you look at this image in the email for the part what I was trying to point out is that this chip has fiducials on them and when you look closely you'll see that they are plated onto the glass chip on one side. When this chip is loaded into the cavity on the machine (between the bond force sensor and the mini-BMC plate) it needs to be inserted with the chrome fiducials facing down. (if it's loaded with the chrome facing up you'll get a parallax when the substrate camera performs measurements of the chip on the mini-BMC plate and it will also set the uplooking camera focus height incorrectly).

Hope this helps. You guys did great work on your own, you are almost there.

Hello Chris,

Your instruction, tool ID picture below and several hours of technical support today are very much appreciated. Thank you for the fantastic support!

You helped me complete all the BH calibration routines today requiring superuser access. The BH appears to be operating as it should be.

Unfortunately, I am still stuck on the last step of auto-calibration and know why. The chip you were telling me was to be picked up from the BMC and placed 10-20 times is not there. There is no one sided chrome piece and I do not recall it ever being there. I will ask our BWI operations if they can send us one. That is the very last step of calibration before testing the tool bank.

There was a glass slide over the force sensor but that shattered last year. I was advised it is not needed and have run force calibration since then with no issues. If I am mistaken and this is the piece you were talking about, please let me know and I can request it. The below statement from the machine basics manual and leads me to think it might be the glass slide I need.

Best regards,

Hi David,

Attached is the procedure. Unfortunately, I don't have a Gen3 machine in the office to take pictures or screenshots for the procedure. Review it and let me know if you have any questions.

Hi Chris,

Good afternoon. On Friday, I tried to fix the theta offset by changing the values but did not have luck. Even when I had the BH tip and PU tool aligned, pick up still failed.

This morning, I noticed the BH tip spins freely, but when I change the direction of rotation, I feel a spot of resistance that goes away after 1 turn. Change rotation direction again and same result. I am speculating the internal encoder came loose. That would also help explain why the theta would not initialize for several days then started “working” again.

We have a bond head arriving from BWI as early as tomorrow. I received confirmation on which controller to purchase. We may have found one available.

Do you have any availability to come here and install the BH and Controller for us? If yes, may we please have a quote?

Our location is:

Thanks for the update, Dave.

Good to know about the venturi setup, obviously a vacuum pump would be preferred. Let me know what you find with the module and if you need anything else from my side. Hope the theta offset fix gets you back up and running.

Hi Chris,

It was great to speak with you and thanks for the troubleshooting advice and support. For the tip vacuum issue, please note our machine is not hooked up to a vacuum line, our machine uses a venturi to generate the vacuum. I am headed to the machine to look for the module and check it, and fix the theta offset.

Hi David,

Thanks for the break-down. It sounds like you have multiple things going on. It's probably easiest if we jump on a call tomorrow. I have a meeting from approx. 8am-9am PST but you can give me a call before or after that, just give me a heads-up. From reviewing the logfiles and your summary I am seeing this timeline of events. Let me know if this is incorrect. If the timeline is correct we should 'only' have to fix the 4deg offset and the tool detection?

Time

Event

~Jan 11

Warning precedes the alarm (customer report)

Jan 13 09:51

First theta homing failure — tracking error + current limit

Jan 13 11:16

Shifts to Error 62 (index pulse not found), Alarm 2.2609

Jan 13 15:16-15:20

Multiple init attempts, all fail with Error 62

Jan 13–~Jan 20

Alarm state persists for ~1 week

~Jan 20

Manual spinning + repeated calibration resolves 2.2609

~Jan 20 onward

Theta homed but ~4° off center

Jan 29 12:23

Air pressure alarms appear (Error 2.501) (This was purposeful. I disconnected the vacuum line to the bond tip to check vacuum was strong. We have had zero air pressure alarms otherwise.)

Jan 29 13:43

Additional Z-axis position loss (This was odd. I was working with our technician to run the machine for solder dispense only, but a Z-axis alarm appeared. Recalibration of the Z-axis resolved the issue and it has yet to reappear. I took it as a symptom of the larger issue we are trying to get to the root of).

Jan 29 14:07-14:11

Tool vacuum check fails repeatedly (75-78, threshold 25-50) (This is the current state. It was OK earlier this week.)

Jan 29 14:34-15:06

Autocalibration fails — can't detect touchdown tool (Missing the PU tool due to the theta axis being off center.)

Jan 29 15:25

Bond force calibration fails

Jan 29 15:27-15:45

Continued tool detection failures during production attempts

Thank you, Jim!

Hi Chris,

Thank you offering to help with our machine woes. This has been an evolving issue since January 13^th.

System info:

MC4 Datacon 2200 evo Automatic Dispense and Component Placement System

SN: 9502610007253

Our machine uses System 2 only and a non-heated bond head with magazine fed waffle packs.

Log files from the beginning of the issue on 1/13 and as of last Friday 1/29 are attached. Nothing of note has changed since last Friday. The January superuser PW expired.

Symptoms:

1/13: Alarm 2.2609: Initialization failed, Axis MtPPThetaSys2 could not be initialized (IMG_4034.jpg). A warning preceded this alarm by a day or two.

This alarm state lasted several days, maybe a week. After manually spinning the bond head tip, running Theta Axis calibration, and running the initialization routine repeatedly, the 2.2609 alarm resolved itself and the machine would successfully initialize.

After the theta initialization alarm was resolved, the pickup tip was rotated off center about 4 degrees (picture attached). The PU tip is no longer aligned with the PP tool locating pins and cannot pick tools up. The machine provides a message to manually place the tip on the bond head. This worked until yesterday. Currently, the machine does not recognize a tip manually placed onto the bond head. Increased vacuum did not resolve the issue. I have verified the tip is firmly in place. Maybe it is the vacuum switch but odd it decided to fail now. There are no hose leaks I can see or hear. I need to trace this farther upstream.

Currently, I need February’s superuser PW so I can recalibrate the bond head tip back to zero degrees. A request for the PW was sent to Besi. I have the UC Calibration tool on hand for this. Once that is resolved, the issue of the PU tip not being recognized by the machine remains. I am cautiously optimistic this will resolve itself or a root cause will be found.

Lastly, it appears the air bearing in the bond head is good. I push it up and it goes down by itself, no sticking. IMG_4116 shows the TD sensor value.

Thank you again for your time on this. I really appreciate the support. I can provide more details as needed. I did not attach videos due to file size.

Hi Lorena,

Vern forwarded over all of your information for the new order & W9 paperwork. It's been informed to me that you have purchased Midas Technology, so we will probably just update our Midas Technology account to Turnpack. If you are wanting to be set up on terms, you will need to fill out our credit application or we can send you a proforma invoice to do a prepayment on your new order.

Please confirm how you would like to proceed.

Hi Lorena,

Vern forwarded over all of your information for the new order & W9 paperwork. It's been informed to me that you have purchased Midas Technology, so we will probably just update our Midas Technology account to Turnpack. If you are wanting to be set up on terms, you will need to fill out our credit application or we can send you a proforma invoice to do a prepayment on your new order.

Please confirm how you would like to proceed.

Good Morning Lorena,

I have been reaching out to your credit references the past couple of weeks with only one response as of today.

I am requesting 2 additional credit references that I can contact because from past experience the vendors - McMaster Carr and Digikey do not respond to credit inquiries.

Please let me know if you have any questions and if you are wanting us to provide a proforma invoice for the order we have in house

Thank you

Hi Lorena,

Vern forwarded over all of your information for the new order & W9 paperwork. It's been informed to me that you have purchased Midas Technology, so we will probably just update our Midas Technology account to Turnpack. If you are wanting to be set up on terms, you will need to fill out our credit application or we can send you a proforma invoice to do a prepayment on your new order.

Please confirm how you would like to proceed.

Good Afternoon Lorena,

I had success with 1 of the two additional credit references you provided with Coast Aluminum but BSC stated you were a credit card only customer.

To be able to approve your account with account terms of Net 30 days, I am need 3 credit references which I currently have only 2.

Please provide 1 or 2 additional references to continue the credit approval process or if you need the motors we can send a proforma invoice.

Let me know

Thank you

Good morning,

Per our phone call, I’m looking for a manual for a Midas De-Lidder. It is serial number 875 and was purchased in 1988.

Our short-term need is to have a procedure for removing and reinstalling a new tool (xx flute dual helix tool). And to know where we can purchase this tool.

Eventually we would also like the manual to help in any future maintenance of this de-lidder.

Thank you for your assistance,
