I was wondering if this may ne a reasonable approach: 1 - Drill the blank copper clad board with slightly oversize holes. 2 - Squeeege conductive epoxy into the holes. Cure 3 - re drill the holes to the correct size 4 - electroplate, photo mask, then etch. This assumes a CNC based drill with good repeatability. It could work with LPKF and other grinders, as well as home brews
