Hi, I'm using a thick-substrate PCB, so that I can include screw terminals on the board and it won't flex too much when the screwdriver is applied. The board thickness is such that DIP pins only just poke through to the copper layer, to the point where soldering could be unreliable. The problem is solvable by drilling larger diameter holes from the non-copper side partially through, so that the packages sit lower on the board. Do PCB manufacturers routinely provide program-controlled drilling of this sort, does it have a name? TIA
