ABSTRACT:
A method of making printed circuits which comprises passing a non-conductive strip of material past a device which repeatedly imparts a desired circuit pattern onto the passing strip so that a succession of identical printed circuit zones are created along the length of the strip. The strip is subsequently wound into a coil which can be stored for use as desired when printed circuit assemblies are to be fabricated. Fabrication of an assembly comprises unwinding the strip from the coil and severing of the strip between the individual printed circuit zones. A backing can be joined to the unwound strip before severing.
