BGA

Group Administrators: 1 | Group Member: 96 | Group Threads: 97

A ball grid array (BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package. The whole bottom surface of the device can be used, instead of just the perimeter.

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.
