So, I'm starting the design for this now... I want it to be sort of like a book where the PCB fits into an area outlined with the gasket material and the glass presses down and forms a tight fit with the PCB in the center...then clamps down.. then the whole thing slides into the 'UV OVen' and gets exposed.. two sides at once.. and if your board is small enough, you can expose several at once.. I'll keep updating the renderings as I get it going.. The frame will be 3D printed, but may have to be either coated in aluminum foil or something to keep the UV from attacking the plastic... I want these to last a long time....through many exposures..
