FAQ:

Question: What is via in pad

Answer: For some pcbs, due to the limited space, the via holes need to be designed on BGA pad. In order to meet this design requirement, we need to drill the hole on bga pad first, then PTH the hole and use resin to plug in the hole. From the pad surface, we won't see any holes. So it won't affect SMT function.
