Hello all,
If you have identified a BGA with corner ball pad cratering, what would
be your suggestions to correct this condition?
Our thoughts:
1.  We plan to evaluate our handling processes to reduce/remove
excessive flex/strain occurring around this part
2.  We plan to evaluate corner bonding or underfilling for the BGA.

Which do you feel would be the best direction to go?  Do you have other
suggestions?
Thanks in advance for all your help

Genny
