Abstract
Abstract A FLAT CONDUCTOR CABLE HAVING MULTIPLE RIBBON-LIKE CONDUCTORS IN SPACED, PARALLEL ARRANGEMENT IN A FLAT STRIP OF INSULATING MATERIAL IS COATED WITH A LAYER OF SHIELDING METAL SUCH AS COPPER BY ROUGHENING THE SURFACE OF THE INSULATING STRIP, CONTACTING THE STRIP WITH AN ELECTROLESS PLATING BATH AND THEN WITH AN ELECTROLYTIC PLATING BATH. CONTACT OF THE METAL SHIELD WITH A GROUND CONDUCTOR IS OBTAINED BY EXPOSING A PORTION OF ONE OR MORE CONDUCTORS ALONG THE LENGTH OF THE CABLE PRIOR TO PLATING. AN OUTER LAYER OF INSULATING MATERIAL IS APPLIED OVER THE SHIELDING LAYER.
