Technical analysis of electronic aluminum foil

The production of electronic aluminum foil is a precision processing process, and the quality of the product has an important relationship with the advanced level of raw materials, control systems and production equipment. From a global perspective, although the production of China's electronic aluminum foil is developing rapidly, European and American companies still have advantages in advanced technology, especially in high-voltage electronic aluminum foil. Because the electronic aluminum foil products have strict requirements for process technology, equipment technology and production management level, the production must be in strict accordance with the process flow and follow the characteristics of the equipment in order to produce qualified products.

In recent years, with the progress of science and technology, the main equipment used in the production of electronic aluminum foil products has been localized, and now the domestic electronic aluminum foil factory uses domestic equipment to produce products, and the quality level has caught up with or even exceeded the products produced in Japan and South Korea. In the choice of control system, the main domestic manufacturers have technology is not very mature, most choose foreign control systems. Technically, the domestic production line and production process is still to imitate and use foreign technology, or choose the technical mode of cooperation with foreign capital.

In order to continuously improve the product characteristics of aluminum electrolytic capacitors, China has many related technological improvements in aluminum foil processing. The use of high purity and high performance aluminum foil material greatly improves the corrosion performance of the material, and at the same time, the leakage current of the formed dielectric oxide film is greatly reduced. With the development of advanced corrosion and formation technology, the specific capacity of negative and anode aluminum foil is further increased, and the leakage current of anode light foil is further decreased. In order to achieve the volume reduction and flattening of capacitors, the processing technology of high specific volume and high strength of aluminum foil has made progress in recent years.
