Lex,
Maybe you want to consider buying your pcb material at eBay. That's where
I've gotten mine. There are sellers for just bare board stock as well as
presensitized. Here's the seller I've dealt with: abcfab (
http://myworld.ebay.com/abcfab/&_trksid=p3984.m1439.l2754). Domestic
USA. 99.9% rating. Very fast shipment. I don't know him or anything, but I
like to hear about good sellers myself.
I've given passing thought that if I wanted to retrofit a single-sided
board with a ground plane that I could use adhesive-backed copper-foil
tape. Some is made explicitly to be conducting (for EMI shielding, etc.).
Some might be found at craft stores, especially ones that carry
stained-glass supplies. Care would be needed with this source that the
material is 1) really copper, and 2) it doesn't have a non-conductive
coating, though if there's real copper underneath some of the coating could
be sanded off so connections can be made. I think it could be directly
solderable, though since it would have a sticky back soldering would need
to be fast. It fast enough anyway. Besides, it wouldn't matter if the
adhesive got warm. It'll cool off. I guess one could also use screws and
lugs to make connections, again mindful of any coating.
In addition to pcb uses, I'm going to try using the foil tape to shield the
inside of a plastic enclosure, jumpering between the pieces. Wouldn't have
to be copper. Could be aluminum, tin, etc.
73,
Todd
