ABSTRACT:
Circuit film strip comprises a continuous strip of plastic film having a repetitive pattern of conductors thereon and indexing holes along its side edges. The indexing holes comprise a layer of metal on the film which extends over a punched hole in the film. The metal layer has an etched hole therein which is produced by the same printing and etching process as is employed to produce the conductors so that the etched holes are precisely located with reference to the conductors.
