Solder Resist PCB Production

[Richard Harris]

Hi,
have a strange question. I can produce very high quality and dense pcb's
using photo resist boards and a 1200dpi printer. But really i need to solder
resist coat the board. Also I have to do this on a budget, the problem is
how to get the solder resist on the board and cheap. It will require very
precise positioning, the only thing I have came up with is modifing a ink
jet printer, but even if I can do that im not sure if a solder resist paint
will go though an inkjet cartridge as its most likely to think.

Any one have any sudgestions about this problem?

And no I cant paint the stuff on with a paint brush

Thanks.

Isn't there a photographic way to do this.

Full board with solderresist, then a layer of photoresist.
Print, remove part of the photoresist. Then with the right solution remove
the solderesist.
Finally remove the remaining photoresist.

You remind me of the guy who,
when asked why he was hitting himself on the head with a hammer,
said "Because it feels so good when I stop".
