Common Applications
Our conductive copper tape is widely used in industries requiring reliable shielding and conduction:
– Electronic component manufacturing (PCBs, semiconductors, sensors)
– Automotive electronics (ECUs, infotainment systems, wiring harnesses)
– Industrial control systems (PLCs, HMIs, power supplies)
– Telecommunication equipment (antennas, routers, base stations)
– Medical devices (diagnostic equipment, patient monitors)
– Aerospace and defense electronics (high-reliability applications)
Application Guidelines For optimal EMI shielding and conduction performance:
1. Clean the surface thoroughly to remove dust, oil, and oxidation before application.
2. Apply the tape evenly with firm pressure to ensure full contact (critical for conductivity).
3. For high-temperature applications, ensure the surface is pre-heated to ≤ 50°C for better adhesion.
4. Store in a cool, dry environment (15-25°C) away from direct sunlight to prevent oxidation.
