ABSTRACT:
In the registration of artwork panels for the manufacture of printed circuit boards, each panel is located, in turn, above two target location areas. Targets are provided upon the panel and these targets are positioned over the target location areas. With light projected from the target location areas and through the panel around the targets, the positions of the location areas and targets are monitored, and the artwork panel is moved to dispose the targets in specific locations relative to datums. The panel is then registered in position prior to a processing step, e.g. the punching-out of registration holes.
