1183 Tape

Tin-Plated Copper Foil with Conductive Adhesive

Data Sheet

Product Description

3M 1183 Tape consists of a 1-ounce deadsof t tin-plated coppe r foi l backi ng and a unique electrically conductive pressure-sensitive acrylic adhesive.

• Deadsoft 1-ounce tin-plated copper foil backing

• Conductive acrylic adhesi ve

• Supplied on a removable liner for easy handling and diecutti ng

Like all 3M shielding tapes, 3M 1183 is available in standard and custom widths and lengths. Standard length is 18 yards.

• Widths from 1/4” to 23”

• Longer lengths up to several times normal length, dependent upon width. Check with Customer Service.

Applications

3M 1183 Tape is typically used for applications requiring exce l lent electrical conducti vity from the application substra te through the adhesive to the foil backing. Common uses include grounding and EMI shie lding in equipment, components, shi e l ded rooms, etc. The tin plating facilitates soldering to the backing and resists oxidation and corrosion.

Shielding Effect i ven ess

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).
