3M EMI Copper Foil Shielding Tape 1194 consists of a 1-ounce deadsoft copper foil backing and an aggressive nonconductive pressure-sensitive acrylic adhesive.
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.
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).
