1245 Tape

Embossed Copper Foil

Data Sheet

Product Description

ounce deadsoft copper foil backing and an

aggressive pressure-sensitive acrylic adhesive.

The edges of the embossed pattern pressed

into the foil cut through the adhesive layer to

establish reliable metal-to-metal contact

between the backing and the application

substrate.

• Embossed deadsoft 1-ounce copper foil

backing

• Conductivity “through the adhesive”

• Supplied on a removable liner for easy

handling and diecutting

Like all 3M shielding tapes, 3M 1245 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 1245 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 EMI

shielding in equipment, components, shielded

rooms, etc. The copper foil backing is

solderable and resists oxidation 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.

to 85dB (30 MHz to 1 GHz).
