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

The way we do this, is to tape a transparent film to the PCB. The printers and chip shooters can read fiducials no problems. Once it has been run through SMT, simply remove the tranparency film and the PCB is ready for use, no mess no cleaning and yo
