Here's a board that used "solder-mask defined pads" for the tiny EPC
BGA GaN fets, with pad stack and mask like EPC recommends. Boards
fabbed by Cirexx.

Those pads are 0.3 mm diameter, a hair under 12 mils. We called out a
0.2 mm solder mask cutout, but the board house didn't do that. I kind
of like them the way they are.
