Solder mask vs non solder mask defined pads

Electronics Forum | Fri Jan 22 16:03:17 EST 2021 | SMTA-64387124

Does anyone see any issues in mixing SMD and NSMD pads within one BGA footprint. We have high current pads which we want to make SMD and the other signal pads to be NSMD

BGA ball vs land design problem??

We've never heard of a situtation where oversized pads caused voiding. Your supplier is correct that the pads on the board should be the same size as the pads on the interposer, but this is to improve reliability issues. Search the fine SMTnet Archi
