Script of failure: CHECKING VPU: UNIT X(0):FAILED
(Note: Device passes and high yield)
>>>answer: device tested is 14x20 at 80/100 pins and does not require VPU because it
only for above 208pins above.
Script of Failure:TESTING POWER SUPPLIES:3OV supply is out of tolerance (30.72)
Power Supplies FAILED
MOTHER BOARD ANALOG:Passed
PIN DRIVER BOARDS:Passed
MOTHER BOARD:Failed
SYSTEM SELF TEST:Failed
1 Error Detected
Status during Programming:Programmed Device Failing with a very LOW YIELD
>>>>answer:Here is another way to calibrate the power supply;
- Go to the Diagnostic Test
- Go to Device.
- Under Device, select PS (power supply). Make sure under Device/Option must be set
to the site you want to view. It will show you all the power supply rating for this
site. If the power supply is out of spec. there is an astrick sign. Below is the
steps if it is out of spec.
- In the front of the machine panel left side unscrew all the screw.
- You will see there is 11 units of PS in there.
- You will need to see which site is for which PS. I believe David
had make some marking previously.
- On the PS there is a Blue color trim pot which you can turn left or right.
Turn it slowly and view the changes on the screen. This trim pot is only adjusting
the 5Vdc and will affect the rest of the voltage. The usual rating for the 5Vdc is
5.14Vdc on automated system. If after adjusting this and you still can't get the 30V
astrick to disappear then the only way is to use software.
The only way to calibrate the site and power supply is to use a service software.
This software is only for BP service usage and we are not in a position to release
this as we had signed NDA with BP.
MAJOR DOWN ENCOUNTERED ON BP4100 LAST JULY 19 TO 20, 2002
Problem: Cannot communicate with the PC(Demo Mode)
Action Done:Check programmer PC and found that parallel port card is faulty.
:Found that site 11 cable connecting to PC was connected reversed.
Remedy: Connect parallel cable to the PC parallel printer port(on mother board)
: Re connect site 11 cable to the correct orientation.
: Re teach all 11 sites for board name: ASM80PQR_TRAY_TRAY
: Test run with the above board name with the device TMS370F16BIAPH
: Monitor for two hours and programming is good.
