Thanks for the info Robin,

Tiffany Tape sounds interesting........

Yes, even though I will be soldering components to it, it's much easier=20
to make an etch line by sticking 2 pieces together than it is to have to=20
solder them together.

As an update, I did find a 3M product of conductive adhesive backed=20
tape, but even 3M couldn't tell me how conductive their adhesive is.=20
They were kind enough to send me a sample however, so I did make my own=20
evaluation. I found 'conductive' mean about 100K ohms for a 1/8 inch=20
wide square junction point between 2 pieces of the stuff. So, using the=20
3M stuff still requires soldering to make the electrical connections.

So, Tiffany Tape might do just as well, or even better than the 3M tape.

Again, thanks!
