3M 1194 Tape consists of a 1-ounce deadsoft copper foil backing and an aggressive nonconductive pressure-sensitive acrylic adhesive.
• Deadsoft 1-ounce copper foil backing
• Nonconductive acrylic adhesive
• Supplied on a removable
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).
