1170 Tape Aluminum Foil with Conductive Adhesive Data Sheet Product Description Applications 3M 1170 Tape consists of a 1-ounce deadsoft 3M 1170 Tape is typically used for aluminum foil backing and a unique electrically applications requiring excellent electrical conductive pressure-sensitive acrylic adhesive. conductivity from the application substrate through the adhesive to the foil backing. Deadsoft 1-ounce aluminum foil backing Common uses include grounding and EMI Conductive acrylic adhesive shielding in equipment, components, shielded Supplied on a removable liner for easy rooms, etc. handling and diecutting Like all 3M shielding tapes, 3M 1170 is Shielding Effectiveness available in standard and custom widths and Many factors determine the true shielding lengths. Standard length is 18 yards. effectiveness of a shielding tape, including Widths from 1/4 to 23 type and thickness of foil, adhesive type, Longer lengths up to several times normal intimacy of contact, smoothness of length, dependent upon width. Check with application surface, strength and frequency of Customer Service. the EMI signal, etc. However, using standard tests and fixtures, it is possible to determine a value for the attenuation. For 3M 1170 Tape, typical shielding effectiveness (far field) is in the range of 60dB to 75dB (30 MHz to 1 GHz).
