Cupric Chloride/HCL compatible liquid
resist ink?
+
I'm looking for a liquid etchant resist ink suitable for use with
Cupric Chloride/Hydrochloric Acid etchant, that can be applied using
a screen-printing technique on traces down to about .005".
This may be an odd request, but here's my reasoning:
- 1. Cupric Chloride/HCL is a relatively "benign" etchant.
- 2. Screen printing of etchant resist would be a damn sight
cheaper than a board house/using transfer film for short run
production (50-100 boards, 12" * 18" board size).
Any help would be appreciated.. Cheap suggestions also would be
good.
