^{3M EMI Embossed Tin-Plated Copper Foil Shielding Tape 1345 Acrylic Adhesive}

^{3M 壓紋 鍍錫 銅箔膠帶 1345 導電丙烯酸膠黏劑}

3M EMI Shielding Tape 1345 is oxidation resistant for excellent long-term EMI shielding, static charge draining, grounding; solderable; easily die cut. This 1.4 tape is an embossed tin plated copper foil with an acrylic pressure-sensitive adhesive on liner. The tape is conductive through the adhesive.

3M 1345 Tape consists of an embossed 1-ounce deadsoft tin-plated 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 tin-plated copper foil backing
• Conductivity “through the adhesive”
• Supplied on a removable liner for easy handling and diecutting

3M 1345 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 tin plating on the copper foil backing facilitates soldering and improves resistance to oxidation and discoloration.

For 3M 1345 Tape, typical shielding effectiveness (far field) is in the range of 75dB to 95dB (30 MHz to 1 GHz).
