Applications
3M 1245 Tape is typically used for applications requiring excellent electrical conductivity from the application substratethrough 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 1245 Tape, typical shielding effectiveness (far field) is in the range of 75dB to 85dB (30 MHz to 1 GHz). .
