You need to verify the footprint of the component! Are they compatabile to
IPC-SM-782? Reduce the width of the pads will also help. Of course, the
problem can be vendor related.
Thanks

Subject: ASS: Cracking of Decoupling Caps
Date: Monday, August 07, 1995 9:26AM
I have a mixed technology board - bottom side smt power supply which is
failing. I suspect that the failure is due to the unreliability of
decoupling ceramic caps.
On reworking the caps they tend to crack.
I have subjected them to thermal shock tests and they seem to retain their
integrity.
Any suggestions? Is it a vendor problem (which seems unlikely) only?
Thanks in advance.
