Copper plated and nickel plated aluminum foil is a thin film technology that is anti-static and electromagnetic interference resistant

     Aluminum foil, copper plated, nickel platedIt is a thin film technology that is resistant to static electricity and electromagnetic interference, which can effectively suppress electromagnetic waves and protect internal electronic components from external interference. The main raw material for copper plating and nickel plating on aluminum foil is aluminum foil, which is covered with a thin film composed of copper and nickel, and has good electrical insulation and heat resistance.

The production process of copper plated and nickel plated aluminum foil is to first treat the surface of the aluminum foil, then apply copper and nickel films on the surface of the aluminum foil, and finally complete the heat treatment and cleaning steps to form the final copper plated and nickel plated aluminum foil. Copper plated and nickel plated aluminum foil has excellent electrical insulation, heat resistance, corrosion resistance, and arc resistance, and is therefore widely used in the packaging of electronic devices, chip packaging, and sensor manufacturing. Aluminum foil plated with copper and nickel has excellent thermal stability, which can effectively resist the effects of high and low temperatures, suppress the deformation and damage of electronic components, and thus improve the reliability of electronic components.

Aluminum foil refers to a thin strip of aluminum and aluminum alloy with a thickness of ≤ 0.2mm. Its hot stamping effect is similar to that of pure silver foil, so it is also known as fake silver foil. Due to the soft texture and good ductility of aluminum, it has a silver white luster. If the rolled thin sheet is mounted on adhesive paper with substances such as sodium silicate to make aluminum foil, it can also be printed. Aluminum foil is generally classified according to its thickness, condition, and purpose.

According to thickness: aluminum foil greater than 0.012mm is called single foil, and foil less than or equal to 0.012mm is called double foil; There are also single zero foils that have a thickness with a zero after the decimal point, and double foils that have two zeros after the decimal point.

According to the state, it can be divided into fully hard foil, soft foil, semi hard foil, 3/4 hard foil, and 1/4 hard foil. Full hard foil refers to the foil that has not been annealed after rolling (fully annealed coil and>75% cold rolling); Soft state foil refers to foil that has been completely annealed after cold rolling; Aluminum foil with tensile strength between fully hard foil and soft foil is called semi-rigid foil; 3/4 hard foil refers to any foil with a tensile strength between fully hard foil and semi hard foil; Aluminum foil with a tensile strength between soft state foil and semi-rigid foil is called 1/4 hard foil.

According to surface condition, it can be divided into single-sided foil and double-sided foil. Aluminum foil rolling is divided into single sheet rolling and double joint rolling. During single sheet rolling, both sides of the foil are in contact with the roller surface, and both sides have a bright metallic luster, which is called double-sided glossy foil. During double rolling, only one side of each foil is in contact with the rolling mill. The side in contact with the rolling mill is shiny, while the two sides in contact between the aluminum foils are dull. This type of foil is called single-sided glossy foil. The minimum thickness of double-sided aluminum foil mainly depends on the diameter of the work roll, usually not less than 0.01mm. The thickness of single-sided aluminum foil is usually not greater than 0.03mm, and the current minimum thickness can reach 0.004mm.

According to the use of aluminum foil, it can be mainly divided into packaging aluminum foil, air conditioning aluminum foil, electronic aluminum foil, and battery aluminum foil.

In addition, Aluminum foil, copper plated, nickel platedIt also has good corrosion resistance, which can effectively prevent corrosion of metal surfaces and significantly improve the service life of electronic components.

In short, copper plated and nickel plated aluminum foil is a very practical technology that can effectively block external electromagnetic waves and resist interference, thereby protecting internal electronic components from external interference. Its application can significantly improve the reliability and stability of electronic components, making it a very practical technology. Therefore, the copper plating and nickel plating technology for aluminum foil is expected to have greater development and application in the future.
