1181 Tape Copper Foil with Conductive Adhesive Data Sheet Product Description Applications 3M 1181 Tape consists of a 1-ounce 3M 1181Tape is typically used for deadsoft copper foil backing and a unique applications requiring excellent electrical electrically conductive pressure-sensitive conductivity from the application substrate acrylic adhesive. through the adhesive to the foil backing. Common uses include grounding and EMI Deadsoft 1-ounce copper foil backing shielding in equipment, components, shielded Conductive acrylic adhesive rooms, etc. The copper foil backing is Supplied on a removable liner for easy solderable and resists oxidation and handling and diecutting discoloration. Like all 3M shielding tapes, 3M 1181 is Shielding Effectiveness available in standard and custom widths and lengths. Standard length is 18 yards. Many factors determine the true shielding 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 1181 Tape, typical shielding effectiveness (far field) is in the range of 60dB to 80dB (30 MHz to 1 GHz).
