that are out of range. Footprint Expert uses the IPC-7351 mathematical model for pad size and location calculations. But we also use IPC-J-STD-001 rules for solder joint goal acceptability

; We have found that when the center pad is completely surrounded by solder mask voiding in the solder joint increases and the ability to clean flux residues out from under these parts is difficult if not impossible.
