Default Re: UV Dry Film PCB technique - experiences to daet.

I worked at a place with a PCB shop. Dry film resist was used. The area working with it had yellow lights and filtered windows from the adjacent areas with plain fluorescent lights.

Air was clean-room filtered and the film was applied with a very high pressure on the roller.

Artwork was photo-reduced from 2:1 tapemasters onto very high density monochrome emulsion film.

Can't afford the volcanic island yet, but the plans for my monorail and the goons' uniforms are done
