Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

I've been following this thread for a while now and it has intrigued
me enough to sacrifice a Lexmark Z52 printer to convert it to a
straight through printer.

The major issues (IMHO) is in finding a resist that will: 1. flow
through the printhead, 2. wet out and print well on the copper
surface, and 3. will not be removed by the etchant.

After a visit to my dentist getting my teeth sealed yesterday, I
started thinking about uv-curable inks. In other words, a 2-step
process, printing the resist and then curing it.

I thought about getting some of the tooth sealer to try, but I
realised I was missing the obvious. We already have uv curable
fluids used for pcb making - the photoresists. I had used a couple
of time years ago and didn't get the results hoped for. I had used
the spray cans of resist to sensitize the boards.

I remember seeing on the web (forgot the link), a range of pcb
making chemical that were sold in apllicator bottles, like liquid
shoe polish. Has anyone used these? Any thoughts?
