3M™ Tin-Plated Copper Foil with Conductive
Adhesive Tape 1183
Data Sheet January 2014
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.

RoHS
2011/65/EC
"RoHS 2011/65/EU" means that the product or part does not contain any of the substances in
excess of the maximum concentration values (“MCVs”) in EU RoHS Directive 2011/65/EU. The
MCVs are by weight in homogeneous materials. This information represents 3M's knowledge and
belief, which may be based in whole or in part on information provided by third party suppliers to
3M.
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.
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).
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.
