> Screw from PCB side is impossible; no access Do you mean "no access after PCB installation" or "no access even during manufacture" ? My screws are assembly time items, so go on the board with everything else. > since this is a redesign If the redesign does not include a new PCB then I can understand the screw prohibition. If there are new PCBs made I assume it means that the system is so packed that there is no room for a screwhead that is wider than a tower. Head height is presumably not the issue?
