ABSTRACT:
A method of punching patterns of holes in printed circuit boards and sheets of material used in the manufacture of printed circuit boards. Each hole pattern punched is precisely positioned with respect to the metallized circuitry or the photographic image of the circuitry on each sheet of material. This method is accomplished with the use of an optical registration punch which automatically positions each sheet of material and punches a pattern of holes therein at a precise position with respect to the circuitry or the image of the circuitry on each sheet of material.
