I'm very familiar with the great board space savings of BGA and all the "claims to fame." However, can someone out there tell me if any concern exist in the inspection realm. Additionally, solder cracking, CTE mismatches, no leads for stress relief, package internal construction, thermal concerns with the smaller package .... in short, reliability concerns are of interest to me ... and quite possibly other Product Assurance Engineers out there. What's the scoop on BGAs and MiniBGAs, FBGAs, et cetera??? James
