) measured over 1 in

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.

effectiveness (far field) is in the range of 60dB

to 80dB (30 MHz to 1 GHz).
