thanks for the link. The prices are kind of on the high side. Their
£2625 dryfilm laminator was a bit off putting.
I couldn't see liquid solder masks on their site. What was the pricing
when you were looking at it ?
I'll try my liquid stuff first. Problems I see using liquid mask is you
first need to make screen printing frame and buy/make a squeegee too.
Mixing would require a 0.1g resolution electronic scale (possibly a $20
eBay pocket scale). A fan forced home kitchen oven could probably do
the 75C bake. I'm assuming you'd clean all equipment with developer
solution. All this sounds like a lot of hassle. Maybe with a some
patients one could get the process down pat. The sales guy said its
pretty easy when you get the hang of it.
