CHO-FOIL®and CHO-FABTM EMI Shielding Foil and Fabric Tape with Conductive Adhesive Customer Value Proposition: Parker Chomerics CHO-FOIL® metal foil tapes provide an economical solution to applications requiring excellent electrical conductivity across substrates. These foil tapes can provide a low impedance connection between a braided cable shield and the metal connector backshell in molded cables. Due to the highly conductive pressure sensitive acrylic adhesive (PSA), the tape can provide an effective shielded cable assembly without the need for soldering the tape to the braid. The uniform dispersion of unique, oxidation-resistant conductive particles in the acrylic PSA produce a very low resistance through the tape. Thus, wrapping a cable assembly with the foil tape, using a slight overlap, can provide an effective prototype cable shielding system. Seams of EMI shielded rooms and other shielded test enclosure setups are more easily sealed with CHO-FOIL tape so as to provide electrical continuity and thus higher shielding effectiveness. Double-sided conductive adhesive is available to ensure leak free seams. The use of CHO-FOIL tape can ensure good electrically conductive mating flanges and corrosion resistant grounding areas. For applications requiring lighter weight and a more flexible electrically conductive tape, the electrically conductive fabric tape, CHO-FABTM, will provide excellent shielding and good corrosion resistant performance. In the case of shielded cables, CHO-FAB is very conformable, strong, lightweight, and doesn’t have sharp edges that are present on metal foil tapes.
