3M EMI Embossed Tin-Plated Copper Shielding Tape 1345
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.
- 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).
