Embossed Tin-Plated Copper Foil

Model # 1345

3m 1345 is a 4.0 mil embossed deadsoft tin-plated copper foil backing and an aggressive pressure-sensitive acrylic adhesive. The edges of the embossed pattern pressed into the foil cut throught the adhesive layer to establish reliable metal -to -metal contact between the backing and the application substrate. 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.
