Subject: An alternative TP hole approach?
From: "thespeakerguy" <thespeakerguy@...>

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
