Re: [Homebrew_PCBs] uv resin for a photoresist substitute

2017-03-01 by Rob

WHAT chemical would wash away the cured UV resin after the board was etched?
I thought the idea of hardening the resin was to make it harden.
Does hardening actually make it stick to copper?

Is it possible to use UV resin as a substitute for photoresist?  Copper would be coated with UV resin and an image would be made in the resin with a UV laser.  The uncured resin would be rinsed away and the board etched.  Would the resin adhere to the copper?   Is it worth running an experiment to try it?
