Black PCB with Green Foil Silkscreen
Harbor Freight shipped via USPS on 5th so it should be here in about a week.
I have been working with painting the topside of SS PCBs and adding a toner silkscreen like image. The acrylic clear coat I was using to protect the toner caused it to run. I tested some conformal coating on the toner. I sprayed it on a PCB pattern that I had printed wrong side up. It did not run so I gave it a few more passes. After the coating dried I placed the pulsar paper in water and the coating with the toner came off in a neat but somewhat fragile clear sheet.
Using the conformal coating I made a very sharp white PCB with black toner lettering under conformal coating. But I screwed it up with a flux remover that reacted with the coating and toner. I could have used soap and water so that is not a problem.
I was thinking it would be neat to make black PCBs with green foil lettering. The problem is that after you paint the board you can not apply the foil because it sticks to the paint. The answer may be to add the top artwork as a decal. I think it would be cheaper to buy the bits form pulsar rather then use a bunch of conformal coating. But it was fun, the pulsar paper is amazing stuff.
