1&#;Copper foil production
The production process of electrolytic copper foil is to oxidize the electrolytic copper first to make copper sulfate solution, and then electrolyze the foil in the foil machine to generate raw foil, which is made into finished products through pickling, roughening, curing and brass plating post-treatment process. It includes two major processes of electrolysis and electroplating. For example, a copper foil production company process conditions: sulfuric acid concentration of 120g / L, 7-9KA / m2, cathode and anode gap of 12mm, the use of IrTa anode can meet the production requirements, to solve the production of current density is very high. It uses a partially immersed in copper sulfate solution constantly rotating metal roller as cathode, continuous electrolysis to produce foil. Electrolytic copper foil is used as a conductive material on single-sided printed circuit boards, with increasing dosage and thinner thicknesses, from thicknesses of 0.15mm, 0.105mm, 0.07mm, 0.05mm and 0.035mm.
Electrolytic copper foil, according to the thickness, can be divided into 105um, 70um, 18um, 12um, 9um, and 5um, etc., of which 12um and 12um or less is generally known as ultra-thin copper foil.

According to the surface treatment process, copper foils can be divided into several types, such as pink foil (copper-plated surface), grayed foil (galvanized surface), and yellowed foil (brass-plated surface).
The IPc standard classifies electrolytic copper foils according to their properties into standard foils (STD - Class E), high density foils (HD - Class E), high temperature high density foils (THE - Class E) and annealed electrolytic copper foils (ASTM E). Annealed Electrolytic Copper Foil (ANN--E), Low Temperature Annealed Electrolytic Copper Foil (LTA--E), Annealed Electrolytic Copper Foil (A--E), and so on.
In Japan, copper foil for printed circuit boards is manufactured by electrolysis of copper sulfate solution, and copper is plated on the cathode of a titanium rotating cylinder with a diameter of 1-2 meters and a height of 2-3 meters, and the copper foil is stripped off at the end of the rotating cylinder. In know the printed circuit with copper foil when the coating titanium anode, the height of the more about 1.3 meters, area surface length of about 2.4 meters, plate thickness of about 25 mm. with titanium-based coating anode, the plate spacing does not need to be adjusted, the anode produces oxygen bubbles intense stirring of the electrolyte, accelerating the movement of copper ions to the surface of the cathode. As a result, the operating current density can be increased to 50A/dm2, which significantly improves the productivity of the electrolyzer. The IRO2 coating applied to the titanium substrate by the thermal decomposition method works well under these dielectric conditions. After setting a very thin platinum-plated intermediate layer, the titanium substrate can be prevented from oxidizing, and the anode life reaches at least 2.5 years.
