ABSTRACT:
A system is provided which utilizes a plurality of sequentially controlled magnetic repulsion punches arranged in a variable array to punch a constantly moving substrate. These punches are disposed adjacent the constant velocity substrate on which holes, or vias are formed as the punches are sequentially fired. The array of punches is placed at an angle with respect to the perpendicular of the direction of movement of the substrate. Thus, a delay is present between the time when the first punch must be fired and the firing of subsequent punches, due to the angle of the array. Therefore, due to this delay between the time the first punch must energized, and the energizing of subsequent punches a single power supply is capable of providing energy to a group of punches. Further, with the system of the present invention, it is possible to punch rows of holes lying in straight rows perpendicular to the direction of movement of the substrate and have different center to center distances on the same substrate, without the necessity of rearranging the array of punches and performing an additional punching operation.
