Homebrew PCBs

Hi David -

>> I have here 0.125mm thick copper foil single-side coated with epoxy.
>> The Epson Color 640 accepts it in "thick mode" switch.

>Thanks for letting me know about that. I'm full of questions:
>- are you a dealer?
At the moment, maybe ;-)

>- if not, who is your supplier?
It was for another project left over.

>- what sizes does it come in?
I can ask the supplier for bigger sizes. At the moment I have 20 x 15 cm parts. One inch is 25.4 mm or 2.54 cm.
Probably it comes on roll.
I guess: if I etch the copper away, the back coating will be fully transparent. Great to make double-sided pcb. Just place front and
back beside, print and etch, fold front and back side (with markers). Laminate it for greater stability or leave the two foils
spray-glued as a elastic pcb.
(I removed a little copper mechanical and can now see thru like glass)

I don't know of your specific printers. It goes thru my old TI microlaser 600 w/o problems.
You must coat copper if you want to print on it with a laser. Electrostatic problem otherwise.
Some printer may work w/o coating, I heart.

>- what are the retail prices?
If there is greater demand, I will look for supply.

>- is it available in small retail quantities, or only bulk?
You can have a single sheet. Of course, I'm located in Germany. Don't know postage prices to you.

At the moment I just printed a sample. There is a need for greater test series...

Hope that helps a little.
