Embossed Tin-Plated Copper Conductive Tape for EMI Shielding Grounding Photovoltaic Solar Energy
Embossed tin-plated copper foil tape (with a thickness of approximately 38μm) uses embossed and flexible tin-plated copper foil as the base material, which is evenly coated with conductive pressure-sensitive acrylic adhesive, and the adhesive surface is laminated with release paper. It can be used as an alternative of 3M embossed tin-plated copper shielding tape 1345.
Embossed Tin-Plated Copper Foil Tape is a high-performance conductive tape designed for reliable EMI/RFI shielding, grounding, and static charge draining in demanding electrical and electronic applications. Built with a durable embossed copper foil that is tin-plated for enhanced oxidation resistance, this tape provides long-lasting conductivity even in harsh environments. The embossed pattern increases surface contact area, ensuring strong mechanical bonding and consistent electrical performance.
Tinned copper foil tape is coated with a conductive acrylic adhesive that maintains excellent adhesion to metals, plastics, and painted surfaces while offering low contact resistance. Its combination of flexibility, conductivity, and corrosion resistance makes it a preferred choice in telecommunications equipment, automotive electronics, power supplies, and aerospace systems. Comparable to 3M 1345 Tin-Plated Copper Foil Tape, it offers superior solderability, easy handling, and reliable performance in both OEM manufacturing and repair operations.
Applications of tinned copper foil tape:
Embossed tinned copper foil tape is commonly used to pass from the adhesive surface to the base material. It offers excellent conductivity, is flexible, and easily coated. It is suitable for grounding and EMI shielding in high-end electronic devices and components. It is also charger collector tape for thin film solar panels. The tin coating provides excellent solderability, heat dissipation, and improved resistance to oxidation and corrosion.
This EMI shielding tape is widely used for EMI shielding of enclosures, grounding electrical components, cable wrapping, and shielding connectors. With its excellent balance of mechanical strength and electrical stability, embossed tin-plated copper foil tape is an ideal solution for industries requiring high-quality conductive tapes for critical applications.
When this product is installed or applied to electronic devices, oxidation of the base material or solder joints will not reduce its shielding effectiveness. Reduced shielding effectiveness can affect the clarity and purity of the electronic device’s sound quality, as well as external (electromagnetic) interference.
We are also able to provide long length foil tape like below picture.
