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).
