Hmmm. That could be trouble from a manufacturing standpoint. From my understanding, and depending upon the assembly process, taller components need more spacing around them. Whereas manufacturers like more space around relatively short BGA's to provide additional room for inspection scopes and to allow for re-working nozzles. I haven't used PADS though. Good luck. Jim S.

Hi Jim, Got it, thanks. I'm switching too much between PADS and Allegro...in PADS, you set a global body to body value.
