While investigating a routing study for a new bga device, I found the vendor used round 20 mil pads on 0402 decoupling caps.This allows fitting the caps between break out vias on their 1mm pitch BGA. Round pad gives about 8 mils diagonally from pin t

Make sure that the side of the square is the diameter of the pad, That is that the circle is inside the square not that the square is inside the circle. normally the aperatures are smaller than the pad to get gasketing. In this case the idea is to
