Ganzhou Optimum Antenna Copper Foil Processing
The commonly used reinforcement materials of copper clad laminate are alkali free (alkali metal oxide content shall not exceed 0.5%) glass fiber products (such as glass cloth, glass felt) or paper (such as wood pulp paper, bleached wood pulp paper, cotton wool paper). Therefore, laminates can be divided into glass cloth base and paper base.

The production process of electrolytic copper foil is simple. There are three main processes: solution raw foil, surface treatment and product slitting. The production process seems simple, but it is a production process that integrates electronics, machinery and electrochemistry, and is particularly strict with the production environment. Therefore, the industry does not have a set of standard and universal production equipment and technology, and each manufacturer shows its own ingenuity, which is also an important bottleneck affecting the improvement of domestic production capacity and quality. In addition, the different requirements of customers have also resulted in the waste of many intermediate products copper foil in manufacturing. The one-time input-output ratio is even less than 80%, and these copper foils have to be manufactured again, wasting resources.

Copper foil is divided into calendered copper foil and electrolytic copper foil according to the preparation process, which accounts for the vast majority of the market. According to the Copper Foil Branch of China Electricity Association (CCFA), at present, domestic manufacturers mainly focus on the production of electrolytic copper foil. In 19 years, the domestic production capacity of electrolytic copper foil is expected to be close to 600000 tons, while that of rolled copper foil is only about 10000 tons.

The copper foil industry belongs to the copper processing industry, which processes copper into extremely thin copper strips or sheets by means of rolling, electrolysis and sputtering, and further applies them as industrial raw materials in various downstream products. The thickness of μ Below m, the thickness varies depending on the scene used.
