Copper Foil Tape is a functional tape made of high-purity copper foil (usually 0.03mm~0.1mm thick) and conductive or non-conductive adhesive.
Its core features include:
Conductive properties: Copper foil itself has strong conductivity, and some models are plated with tin or nickel to enhance oxidation resistance.
Electromagnetic shielding: It can absorb or reflect electromagnetic waves to protect equipment from interference.
Flexibility: It is easy to bend and fit the curved surface to adapt to complex structures.
Temperature resistance: The operating temperature range is usually -20°C to 150°C, and the high-temperature model can reach 200°C.
Core application scenarios of copper foil tape
Electronic equipment manufacturing
Circuit board shielding: Cover sensitive areas of PCB boards to prevent signal interference.
Ground connection: Used for grounding electronic components to improve equipment stability.
Communications and radio frequency technology
5G base station antenna: Shield high-frequency electromagnetic radiation to ensure signal transmission quality.
Radio frequency identification (RFID) tag: Enhance antenna conductivity.
New energy and automotive industry
Power battery pack shielding: reduce electromagnetic interference inside the battery pack and improve safety.
In-vehicle electronic module: shielding precision equipment such as vehicle navigation and radar.
Architecture and home improvement
Anti-static floor joint treatment, local shielding of smart home devices.
How to choose the right copper foil tape?
1. Conductive performance requirements
Fully conductive type: The adhesive layer contains conductive particles (such as carbon or silver), which is suitable for scenes that require double-sided conductivity (such as grounding).
Non-conductive adhesive backing type: Only the copper foil is conductive, and the adhesive layer is insulated to avoid the risk of short circuit.
2. Substrate and surface treatment
Pure copper foil: The conductivity is the best, but it is easy to oxidize, and it needs to be tinned or coated with a protective layer (such as acrylic acid).
Thickness selection: The conventional thickness is 0.05mm, and 0.1mm or more can be selected for high shielding requirements.
3. Adhesive type
Acrylic adhesive: Strong temperature resistance, suitable for high temperature environment.
Rubber adhesive: Good initial adhesion, suitable for quick pasting.
4. Industry certification
Give priority to brands that have passed UL and RoHS certification to ensure environmental protection and safety.
