BGA device continuity testing of solder connections | 16 August, 1999

Hello I am looking for help in determining a simple (software based) method for testing the continuity of individual pins on an SRAM devices packaged in BGA. Can you help, or do you know someone who can help? Or do you know of an internet resouce which might help? Your time in greatly appreciated.

The biggest problem we have with the DCM right now is identifying which BGA device to replace. We can identify a problem with the memory with software diagnostics, but narrowing it down to a particular chip or signal is giving us trouble.

Thank you in advance for your time and effort.

However, X-Ray can help when an electrically "bad" module is detected. It certainly can be of help with shorting/bridging and often with minimal or insuficient solder.
