3M™ EMI Embossed Tin-Plated Copper Shielding Tape 1345

The 3M™ EMI Embossed Tin-Plated Copper Shielding Tape 1345 is engineered for high-performance electromagnetic (EMI) and radio frequency (RFI) shielding in harsh industrial and electronic environments. Its unique construction features a tin-plated embossed copper foil backing and a pressure-sensitive conductive acrylic adhesive, enabling exceptional conductivity through both adhesive and backing.

Whether it’s used for flexible printed circuit (FPC) attachment, under-the-hood automotive electronics, or EMI shielding in metal assemblies, the 1345 delivers high reliability with superior thermal and oxidation resistance. The embossed surface enhances grounding contact, while the tape is engineered for excellent converting performance including die-cutting, sheeting, and spooling.

Applications – Where to Use 3M™ 1345 Shielding Tape

EMI/RFI Shielding in electrical enclosures, cable assemblies, and PCBs
Grounding solutions in automotive control units and EV systems
Flexible Printed Circuit (FPC) attachment
Telecommunications and sensor systems
Heat-intensive processing environments including lead-free solder reflow
Corrosion-sensitive electronics requiring tin surface compatibility

Product Benefits – Why Choose 3M™ EMI 1345 Tape?

Tin-plated surface resists corrosion and ensures solder compatibility
High-temperature resistance – withstands up to 260°C short-term exposure
Conductive adhesive system – ensures excellent electrical contact and shielding
Embossed copper structure – improves contact, minimizes signal reflection
Low outgassing, strong adhesion – ideal for sensitive electronic applications
Engineered for converting – maintains stability during die cutting and spooling

This product shares key characteristics with 3M™ GPT020 family standards for high-temp adhesives and is particularly suited to environments requiring robust mechanical and thermal performance.
