. Laser direct imaging exposes certain parts of the board to light in the shape of the PCB pattern. Any unexposed parts of the board will develop off, leaving the remaining film as an etch barrier The remaining film serves as an etch barrier that will be removed from the exposed copper to form the copper circuitry
