Product Description:
3M 1181 conductive copper tape , consists of a 1-ounce deadsoft copper foil backing and a unique electrically
conductive pressure-sensitive acrylic adhesive.
• Deadsoft 1-ounce copper foil backing
• Conductive acrylic adhesive
• Supplied on a removable liner for easy handling and die cutting
Applications:
3M 1181 conductive copper tape is typically used for applications requiring excellent electrical conductivity from the
application substrate through the adhesive to the foil backing. Common uses include grounding and EMIshielding in equipment, components, shielded rooms, etc. The copper foil backing is solderable and resistsoxidation and discoloration. Shielding Effectiveness Many factors determine the true shielding effectiveness of a shielding tape, including type and thickness of foil, adhesive type, intimacy of contact, smoothness of application surface, strength and frequency of 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).
