Automotive Electronics Copper Foil Tape

Automotive Electronics Copper Foil Tape is a specialized adhesive tape used in automotive electrical and electronic applications. It consists of a thin copper foil backing with a conductive or non-conductive adhesive, offering shielding, grounding, and EMI/RFI protection.

Key Features:

Conductivity – High electrical conductivity for grounding and shielding.
EMI/RFI Shielding – Blocks electromagnetic and radio frequency interference.
Heat Resistance – Withstands high temperatures common in automotive environments.
Flexibility & Durability – Conforms to irregular surfaces and resists vibration.

Thickness: usually between 0.025mm and 0.1mm (1 to 4 mils), common 0.05mm, 0.08mm, 0.1mm, etc., different thickness of the tape is suitable for different applications and shielding requirements.
Width: generally between 3mm and 1000mm, can be customized according to the actual needs of the narrower tape can be used for small electronic components shielding and connecting, wider tape is suitable for large area shielding and grounding occasions.
Length: Common length specifications are 10m, 20m, 30m, 50m, etc. Special lengths can also be customized according to customer needs.

Automotive Electronics Copper Foil Tape Features

High conductivity: using high purity copper foil as the base material, such as electrolytic grade copper foil, with extremely high conductivity, can provide a low resistance path for the current, to ensure fast and stable signal transmission between automotive electronic devices, reduce signal attenuation and interference.
Good adhesion: Equipped with high-performance conductive adhesive, such as acrylic conductive adhesive, it has good adhesion to various surfaces, including metals, plastics, insulating materials, etc. It can realize firm adhesion on different shapes and materials of automotive electronic parts, and keep the adhesion stable under high temperature, vibration and other environments.
Excellent shielding performance: it can effectively shield electromagnetic interference (EMI) and radiofrequency interference (RFI), preventing the intrusion of external electromagnetic waves by wrapping electronic equipment or lines, and preventing the leakage of electromagnetic radiation generated by internal electronic components, ensuring the normal operation of the automotive electronic system, and avoiding the mutual interference between components.
Weathering and corrosion resistance: It can withstand all kinds of harsh environmental conditions in the process of automobile use, such as high and low temperature changes, humidity, oil, ultraviolet radiation, etc., with good weathering and corrosion resistance, to ensure the long-term stability of performance, and will not lead to environmental factors that lead to a decline in the performance of the tape or damage.
Flexibility and processability: Copper foil itself has good flexibility, easy to bend and fold, can adapt to various complex spatial structure and shape requirements inside the car, easy to install and use, according to the actual needs of cutting, die-cutting and other processing, made of different sizes and shapes of the tape to meet the shielding and connecting needs of different electronic components.

Automotive Electronics Copper Foil Tape Applications

Common Applications in Electromagnetic Shielding: Used for shielding the shells or circuit boards of electronic devices such as car radios, navigation systems, Bluetooth modules, etc., to prevent external electromagnetic interference from affecting the normal reception and processing of signals, and at the same time to avoid the electromagnetic radiation generated by these devices from interfering with other electronic systems in the car.
Grounding connection: Realize reliable grounding between automotive electronic parts and car body or chassis, provide low resistance path for electrostatic discharge and fault current, prevent static electricity accumulation and electrical faults from damaging electronic equipment and personnel, and safeguard the safety and stability of automotive electrical system.
Circuit Repair and Connection: In the process of repairing automotive electronic equipment, it can be used to repair damaged printed circuit board (PCB) circuits, realizing the reconnection and conduction of circuits by pasting copper foil tape on broken or short-circuited circuits, as well as temporarily connecting or fixing electronic components to facilitate maintenance and debugging.
Heat dissipation: Because copper has good thermal conductivity, copper foil tape can be used for heat dissipation of automotive electronic equipment, such as adhering to the surface of power amplifiers, power supply modules, LED lights and other heat-generating components, the heat will be quickly conducted out to improve heat dissipation, reduce the temperature of the components, and prolong the service life of the equipment.
Decoration and marking: In the interior and exterior of the car, it can be used as decorative elements, such as pasted on the door handle, dashboard, center console and other parts of the car to create a metallic texture and unique decorative effect, but also can be used to make vehicle logos, warning signs, etc., to play a role in marking and reminding.
