Hello,Technetters!
Skipping the horror story,I have a question to printed circuit
manufacturers:
How do you ensure the integrity of the plating in small vias?
We require the manufacturer's cross sections as a proof of test
for our circuits.Very seldom,they contain small vias.
But,anyway,the failures found recently in our line are in random places
on the boards.
Are there other tests on bare boards which can detect reliability
problems ?

Thank you
Gaby
