Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

Hi I've ben reading this group for a while and I feel confident
enough to make my firt PCB. I decided to use the PnP transfer paper
and iron it on. Right now I manage to transfer my design to a copper
bard fairly well. The thing is that I see all those holes and they
are so smal. I hear some people drill the holes after they etch
becase they can use the hole as a guide. Well, I tried driling a few
holes in a practice pice of copper board nd I keep missing the mark.
The board an't een etch yet but I wondering if I should drill the
holes fist that way I can add more resist in case I screw up.

My second question is about sharpie pen. When I was transfering my
desing a few pads and trces did not transfer properly. I took a
sharpie pen and fille in the missing gap. Will the sharpie resist
ferric cloride or will it fail?
