Bga failures

2017/2/27 23:10:47

All,

We have a board that has failed at burn in.

There is a 672 BGA on the board. When the test guy presses down on the BGA the board will pass !

What am I looking at here? Board finish is ENIG - could this be black pad / what should I do to diagnose the problem?

Any advise very much appreciated.
