Greetings,
I understand BGA reliability is a very complex subject. Folks had been
doing DOEs for years trying to determine the significant factors
involved. For most perimeter PBGA, corners joint seem to be the weakest
link. I wonder if anyone out there had done studies on enlarging just
the corner pads of a BGA to enhance reliability.
Thanks,
M. Yuen
