Hi,
Recently I have met a problem with HP3070 during board under test.
Please refer attached of digital/u27 failure during ICT test. The board able to PASS while testing at other HP3070 tester.
Diagnostics also showed passed in module 2 and 3.
Action taken:
Since the failure indicates that BRRCC node 220125 where located at module 3 slot 8. Therefore, I swap pin card in module 3 slot 8 with other slot still unable to pass.
Thus, above case indicates that board able to PASS by using other HP3070 tester within same test program been used, and diagnostics result showed pass
between module 2 and module 3.
Please advise and I really appreciate it.
Thanks
Regards,
David Lim

this is probably a marginal test that passes on one system but not on another and could be due to timing, this error is related to voltage being present- you should check that node listed on the schematics and its probablky a fixed node or has power present.
so check that you are not driving onto a node that has voltage present
is this the first test in the digital suborutine ? could be that you need to move the test to middle of digital routine or try to shorten the vector cycle and receive delay inside the test by 100n each (i.e. if vector cycle is 400n, change to 300n, and if receive delay is 300n, change to 200n) you wont be able to change vector cycle below 160n anyway ,
