Principle A layer of photosensitive material (photosensitive oil or dry film) is applied to the copper foil on the board surface, and PCB manufacturer should be use the position is exposed by black film, This applies to most PCB factories, especially

I'm looking for what I call Mylar, for lack of a better name. We used it at Digital/Compaq to help us knead paste and also to check alignment of prints without actually applying any paste to the module. It was about 4-5 mils thick, clear and came in
