Jeremy,
1. Where do you buy TSP? I chceked and it is some kind of a cleaner.
Sounds like a great suggestion. I searched this board and it wasn't
mentioned before.
2. What do you use for 'activating' the holes, to make the conductive
so the copper can be later deposited electrochemically?
3. For the others benefit, I am adding this link according to
Jeremy's suggestion:
http://www.caswellplating.com/kits/flashcopper.html
Once Jeremy tells us what to use to make the holes conductive, we
have all crucial details to make plated holes in a homebrew manner,
right?
