: The BGA pad size calculations... Author: Tom HSubject: 2430Posted: 22 Jan 2019 at 8:27amThe BGA pad size calculations are the same in the original 2005 release of IPC-7351 and the 2007 IPC-7351A and 2010 IPC-7351B

. IPC is changing the mathematical model for BGA pad calculation and it won't be public for several months. IPC-7351C is being slow walked though the committee
