ABSTRACT:
A process is disclosed for forming ultra-thin electrical interconnection flex cables. A thin metallic foil ribbon is first coated on one side with a vapor deposited insulating material. The uncoated side of the metallic foil ribbon is then exposed and etched into a plurality of spaced apart conducting lines. The surface of the conducting lines is then coated with a second layer of vapor deposited insulating material. The resulting flex cable is substantially thinner, more flexible and less thermally conductive than flex cables fabricated by previously known techniques.
