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

Last week you all may remember me having a ton of problems getting
toner to stick to some PCB material. Alan suggested that I pre-etch
the board to see if that would help. It was tried and seem to improve
the adhesion on the smaller test samples, but not on the larger
boards.

I am wondering if any of you chemically smart folks here can shed some
light on what would happen to silicone when imersed int he ferric
chloride?

This new board material is rather shiny, more so than the previous
material I have bought in the past. So I suspect that there is some
sort of coating on the boards that is causing me these problems.

Thanks for the input!
