I'd like to build a UV box to do positive resist exposure. The
presensitized boards are 5 by 7 inches, so the box and lamps need not
be too large. Also not too hot as this box is only open on the bottom.
LED's are under consideration but so far a pre-made PC board to hold
400 or so is too expensive. The board is nothing more than etched
parallel lines with drilled holes every .1 inch. UV lamps are a second
choice but they tend to fade and burn out over time.
What are your recommendations?
