. I am currently pondering how best to do this. Right now I have s60r12 pads with v50h25 vias, and Expedition is nudging the vias slightly, indicating that I have cut things just a little too close

. I always "Flood Over" every via in a PCB layout expect those that are via-in-pad will have a thermal relief. The via-in-pad vias have to be specially marked on the fabrication drawing as they need to be plated, plugged, capped, surface finish and planerized flat so that you cannot tell if there is a hole or not
