Homebrew PCBs

I am not sure if the paint would work in an inkjet head. It is water-based,
I guess that's good. On the other hand, it's quite thick. Maybe if it's
thinned enough and printed in several layers it would work. You need to have
a fairly thick layer of this paint to get it work well as a soldermask.

For me, this method was quite attractive for two reasons: First, the paint
is cheap and available everywhere. Second, I already got the toner transfer
process working well, and this is quite compatible with it, it was a mere
extension.

Right now, it looks like curing the paint in two steps is the key... The
first cure (low temp - 120C) gets the paint strong enough to resist solvent,
but not too resistant so that the solvent would remove only the toner-masked
areas. The second cure (high temp - 160C) really fixes the paint in place
and makes it solvent resistant.
