Hi, i did a few test boards yesterday. I took little precaution with regards to exposure with house lights. Results seemed okish, apart from some random splatterings of copper left, and a few of my pads were a bit shite.
Quite good though for first atempt.
I exposed with sad lamp, plus 10 UV and 5 white leds. seemed to do the trick!
Im getting a strip blacklight soon, which hopefully will cut exposure time, and increase quality of boards.
One question, How do you get rid of the foul ferric chloride stuff?
thanks
