1245 Tape
Embossed Copper Foil
Data Sheet
Product Description
3M
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.
effectiveness (far field) is in the range of 75dB
to 85dB (30 MHz to 1 GHz).
