Double Conductive Copper Foil Tape | Extreme Conductivity, Engineered for Complex Geometries

Core Advantages & Key Features

• True Bi-Directional Conductivity for Seamless Circuits This is not just an ordinary conductive tape. Its unique double conductive design ensures that current flows not only along the copper foil surface but also through the entire adhesive layer, providing a perfect electrical connection to any contact surface. This gives you unprecedented design freedom to form a complete grounding circuit even in the most complex structures.
• Unrivaled EMI Shielding Effectiveness Thanks to its fully conductive properties, this tape delivers the highest level of EMI/RFI shielding. It effectively absorbs and reflects electromagnetic waves, completely eliminating external interference and ensuring sensitive circuits operate stably in any electromagnetic environment.
• Exceptional Solderability and Ultra-Low Impedance Inheriting the superior properties of copper, our tape features extremely low surface impedance and excellent solderability. Engineers can solder directly onto the tape to create permanent and robust electrical connections, greatly simplifying complex device maintenance and prototype development.
• Powerful Adhesion, Designed for Reliability Despite its double conductivity, the tape’s adhesive power remains strong. It adheres firmly to various substrates and can easily withstand mechanical vibration and temperature changes, ensuring the long-term stability of shielding and grounding connections.

Client Testimonials & Case Studies

“We were looking for a solution to a complex chassis grounding issue. Traditional single-conductive tape always left ‘blind spots’ at the corners. This double-conductive copper tape perfectly solved the problem. It’s like a custom-fit, invisible shield for our devices, and it helped us pass all our rigorous EMC tests.” — Chief Engineer, Industrial Control Equipment Manufacturer

Frequently Asked Questions (FAQ)

• Q: What is the fundamental difference in performance between double and single conductive tape? A: The key difference lies in the conductive path. Single conductive tape relies on the adhesive layer for conductivity, while double conductive tape is conductive on both the adhesive side and the copper foil backing, ensuring a more comprehensive electrical connection and more reliable shielding, especially on complex curves and seams.
• Q: Will this tape interfere with wireless communication (e.g., Wi-Fi)? A: On the contrary. Its purpose is to shield and guide electromagnetic waves, effectively reducing electromagnetic interference from internal components, thereby improving the quality and stability of wireless communication.
• Q: How can I ensure the best grounding effect? A: The best effect relies on a clean, dry surface. Ensure the surface to be bonded is free of oil and dust, and maximize the contact area between the tape and the surface.
