[SI-LIST] Voids in Solder Joints

Hi,

I have been troubleshooting a board related issue. I have a BGA device
soldered on the board which is giving me functional failures. After running
x-rays on the device I found some voids in the solder jointon most of the
solder balls. 

I am not sure what kind of problems arise due to voids. Voids does not mean
that there is an open joint. I have curve traced al the pins and they give
me the correct characeristics so I guess it is making contact. But what
would a void do when passing a signal is what I am not sure about.

If anyone has dealt with similar issue your feedback would be very helpful.

Thanks

Regards,
Deepali
