for pattern position with +/-2mil tolerance, pattern width may minus 0.5mil max with the traditional auto exposure.etching tolerance determined by the base copper foil.

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
