Abstract

Utilization of a hologram to store a plurality of circuit patterns for the workpiece in printed circuit generation requires certain considerations in the holder assembly. This is required in order to minimize stresses in the holder and to protect the emulsion surface of the hologram. Main frame 1 of rectangular shape is provided with an opening which supports hologram 2. A portion of frame 3 extending inwardly provides a mounting location for workpiece 4. A tank positioned within frame 1 and shown generally at 5 symbolizes various tanks, fixtures and other equipment required in processing steps. Since the hologram is not within area 5, the hologram is protected from the processing steps. Successive images are projected onto workpiece 4 from hologram 2 by a multiplexing technique.

The various incident angles are shown as lines 6.
