We are redesigning a board with a 32 pins chip from a 64 pins. For the old board, we have to use QFN64 due to the size. For the new board, we might be able to use either QFN32 or TQFP32. QFN does not offer much area savings, since we cannot route signals under the ground pad. Can we run a via/trace on the channel between the ground pad and outside pads? Any opinions?
