Hi all.
I have newly started Manufacturing of PCB's using DUPONT RISTON photoresist dry film.
My problem is, as per the datasheet, it is not reliable to use to film is normal room lights and only to use in dark room. how can i use the film in dark room. when i am not able to see anything. can i use any RED or GREEN (20 x 0.25 watts) LED's, so that the things are bit visible.
