3M™ Embossed Tin-Plated Copper Shielding Tape 1345 combines the oxidation resistance and superior solderability of tin plating with 3M's embossed electrical contact technology. The embossed foil teeth penetrate the adhesive barrier, establishing positive electrical contact with the mating surface. Ideal for connector shielding, seam wrapping, and grounding in corrosive or humid operating environments.
Key Performance Highlights
- Dual-sided tin plating resists oxidation and facilitates direct soldering in harsh climates
- Embossed backing cuts through adhesive layer establishing immediate low-resistance circuit
- Excellent shielding effectiveness (>85 dB attenuation across broad RF frequencies)
- Meets UL 510 flame retardancy and RoHS environmental requirements
Recommended Industrial Applications
Severe-environment grounding, connector backshell shielding, military and communications equipment
