faut with a 672 BGA

2017/2/28 21:05:26

All,

I have an intermittent faut with a 672 BGA where it fails in test but upon applying pressure to the BGA it works.

Clearly there is an issue with the wetting of some Balls causing a poor connection.

My profile looks spot on -

I think I posted this before but never really came to any conclusion ..

What tests can I get carried out to pinpoint the problem?
