Applications
3M 1194 Tape is typically used for
applications requiring economical electrical
bonding, grounding, and EMI shielding. 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 1194 Tape, typical shielding
effectiveness (far field) is in the range of 50dB
to 60dB (30 MHz to 1 GHz).
