Cu applications

[sampi]

Hi all.

I am in search of a liquid with for following application:

I have a PC board covered with 100micron Cu layer. I want a liquid to map/draw/print and circit on the Cu. It have to adhere to the Cu. There after I want to use FeCl3 to dissolve the copper not covered by the "liquid". Then I want to remove the liquid from the Cu.

Any suggestions will be much appreciated.

Google photo resist printed circuit board
I got 879,000 hits.
There's also toner transfer etching, which is maybe easier. 41,400 hits.

If low resolution is rewquired, offset printing reenforced
with Syrian asphalt is a cheap and fast process, able to
produce thousands of sq.feet of PCB per day.
