Product Description
3M? 1181 Tape consists of a 1-ounce
deadsoft copper foil backing and a unique
electrically conductive pressure-sensitive
acrylic adhesive.
? Deadsoft 1-ounce copper foil backing
? Conductive acrylic adhesive
? Supplied on a removable liner for easy
handling and diecutting
Like all 3M shielding tapes, 3M 1181 is
available in standard and custom widths and
lengths. Standard length is 18 yards.
? Widths from 1/4” to 23”
Applications
3M 1181Tape 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.
For 3M 1181 Tape, typical shielding
effectiveness (far field) is in the range of 60dB
to 80dB (30 MHz to 1 GHz).
