High-Performance Copper Foil Tape

 

High-performance copper foil tape is a functional material. Copper foil tape consists of a copper foil backing coated with conductive or non-conductive acrylic pressure-sensitive adhesive. It exhibits excellent conductivity performance and EMI shielding capabilities for various applications. Its excellent conductivity and flexibility make it a key shielding solution in the fields of electronic manufacturing, communication equipment, and automotive electronics.

 

 

• Super strong conductivity
  Copper tape adopts 99.98% high-purity electrolytic copper foil to ensure efficient current transmission. Significantly improve the grounding efficiency of equipment, reduce signal loss, and is suitable for high-frequency circuit shielding.
  Full-band electromagnetic shielding
  Effectively block high-frequency interference of 5G/IoT devices. Ensure the stable operation of sensitive electronic components in complex electromagnetic environments.
  Double-sided conductive adhesive technology
  Conductive copper tape features nano-level conductive particles added to the adhesive layer, enabling point-to-point conduction between the tape and the substrate. A reliable grounding path can be established without welding, simplifying the installation process.
  Industrial-grade environmental tolerance
  Temperature range -20℃~120℃, resistant to grease, solvents, and UV aging.

High-performance copper foil tape is an ideal electromagnetic compatibility (EMC) material in the following fields:
PCB board shielding: covers the edge of the circuit board to suppress edge radiation interference.
Cable harness shielding: wraps the harness to reduce electromagnetic leakage.
Plastic chassis EMI protection: sticks to the inner wall of the chassis to create a Faraday cage effect.
New energy battery pack signal isolation: prevents BMS signal crosstalk and improves the safety of electric vehicles.
RFID equipment anti-interference: shields metal interference around the reader and writer to improve recognition accuracy.
