3M 1183 Tin-Plated Copper Foil with Conductive Adhesive Tape

Description:

• 3M™ Tin-Plated Copper Foil Tape 1183 consists of a 1-ounce dead soft tin-plated copper foil backing and an electrically conductive, pressure-sensitive acrylic adhesive. This tape is supplied on a removable liner for easy handling and die-cutting. It has excellent solderability.

Applications:

• Tin-Plated Copper Foil Tape 1183 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 EMI shielding in equipment, components, shielded rooms, etc. The tin plating facilitates soldering to the backing and resists oxidation and corrosion. 

Specifications:

• Tin-Plated Copper Foil Tape 1183 is a tin-plated copper foil tape with acrylic conductive pressure-sensitive adhesive. 

• The tape shall be coated on one side with pressure-sensitive adhesive, which shall not require heat, moisture or other preparation prior to or subsequent to application. The adhesive coating shall be smooth and uniform and be free of lumps and bare spots. There shall be no separator between adjacent layers of the roll. The tape shall perform at a temperature of -40F° (-40°C) to 266°F (130°C) without substantial loss of tensile or electrical properties.

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 1183 tape, typical shielding effectiveness (far field) is in the range of 70dB to 85dB (30 MHz to 1 GHz)
