Cu Application
Cu Application
(OP)
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.

If you want to make a circuit board, there are many places where PCB boards pre covered with a photo-sensitive resist are available including places like www.digikey.com
However, if you have a special material you are trying to etch, I would try the Dalpro materials or do a Google search to find a film or photosensitive chemical for coating your material.

A laser printer printing onto acetate is the best way of getting an artwork to use in a photo-etching application if you can't get access to a proper Gerber photoplotter.

RE: Cu Application
offset printing is the way.

The tone adheres much more readily, because it's paper, and I seem to get far fewer pinholes.
With the correct UV exposure timing I get wonderfully solid tracks and pads.
Not my own idea, but one which I found on the web.
