Copper foil conductive die-cut parts are patches made using the conductivity of copper foil, with excellent conductivity, thermal conductivity and plasticity. As a cathodic electrolytic material, copper foil has high conductivity, high thermal conductivity, good plasticity and corrosion resistance, so it is widely used in electronics, communications, construction, decoration, aerospace and other fields; because of its excellent processability, it also plays an important role in the electronics industry, communications and electromagnetic shielding.
XINBIXI will introduce our copper foil conductive die-cut parts production process to you today:
Material preparation: First, you need to prepare copper foil. Copper foil is made of copper and a certain proportion of other metals. It has low surface oxygen characteristics and is easy to adhere to different substrates. In addition, auxiliary materials such as conductive agents (such as superconducting carbon black), binders (such as PVDF) and solvents (such as N-methylpyrrolidone) are also required.
Slurry preparation: Use an electronic scale to mix the active material, conductive agent and binder in a certain ratio (such as 8:1:1), then add the solvent and stir with a magnetic stirrer for more than 12 hours until a uniform black slurry is obtained.
Copper foil treatment: Cut the copper foil into the required size and gently wipe the surface with degreased cotton dipped in anhydrous ethanol to remove oil and impurities.
Coating: Coat the prepared slurry on the surface of the copper foil. You can use a coating machine to control the coating thickness and speed.
Drying: After coating, vacuum dry the copper foil carrying the active substance to remove the solvent and moisture.
Die-cutting: Die-cut the prepared copper foil to make the shape of the copper foil conductive die-cut parts you need.
Copper foil conductive die-cut parts play an important role in all walks of life:
Electronic industry: Copper foil conductive die-cut parts are a key component of printed circuit boards (PCBs). As conductors, they connect various electronic components to form complex circuit networks. In addition, copper foil is also widely used in the manufacture of electronic components, such as inductors, capacitors, etc., to improve the performance and stability of products.
Communication field: Copper foil conductive die-cut parts are widely used in the manufacture of products such as cables, wires and antennas. Cables and wires made of copper foil have the characteristics of low resistance and high transmission efficiency, which can ensure the stable transmission of communication signals. Copper foil antennas have become an important choice in fields such as mobile communication base stations and satellite communications due to their excellent electromagnetic properties and low cost advantages.
Electromagnetic shielding and antistatic: Copper foil conductive die-cut parts are also widely used in the fields of electromagnetic shielding and antistatic. Copper foil has excellent conductivity and electromagnetic shielding effect, which can effectively isolate the interference of electromagnetic waves and protect electronic equipment and personnel from the harm of electromagnetic radiation. At the same time, copper foil also has good antistatic properties, which can prevent static electricity accumulation and discharge from damaging equipment.
Other applications: Copper foil conductive die-cut parts are also used in computer monitors, computer peripheral wires and transformer manufacturing, air conditioning pipelines, smoke extractors, refrigerators, water heaters, etc. In pipeline joints. During high-frequency transmission, electromagnetic wave interference can be isolated and high temperature resistance can prevent spontaneous combustion.
