BackFix Notes from MK's PCB livestream Footprints: - avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals vias connect through the board, connecting a trace on the mid surdos.
