^{3M EMI Embossed Copper Foil Shielding Tape 1245 Acrylic Adhesive}

^{3M 金屬壓紋銅箔膠帶1245非導電丙烯酸膠黏劑}

3M EMI Shielding Tape 1245 is UL 510 flame-retardant and ideally suited for EMI shielding; static charge draining, grounding; solderable; easily die cut. This 1.4 tape is an embossed copper foil with an acrylic pressure-sensitive adhesive. This tape is conductive through the adhesive.

3M 1245 Tape consists of an embossed 1-ounce deadsoft copper foil backing and an aggressive pressure-sensitive acrylic adhesive. The edges of the embossed pattern pressed into the foil cut through the adhesive layer to establish reliable metal-to-metal contact between the backing and the application substrate.
• Embossed deadsoft 1-ounce copper foil backing
• Conductivity “through the adhesive”
• Supplied on a removable liner for easy handling and diecutting

3M 1245 Tape is typically used for applications requiring excellent electrical conductivity from the application substrate through 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.

For 3M 1245 Tape, typical shielding effectiveness (far field) is in the range of 75dB to 85dB (30 MHz to 1 GHz).
