Problems solved by technology

Copper foil with copper sulfate solution attached to the surface must be subjected to subsequent surface treatment within 2-3 days, otherwise severe oxidation will occur on the surface, which will cause blackening of the surface of the electrolytic copper foil, which will seriously affect the resistance to dip soldering Index and anti-peeling strength, and the subsequent surface treatment process is difficult to remove the oxide layer on the surface, so the quality and service life of electrolytic copper foil will be reduced, and in severe cases, a large number of products will be scrapped

Description

technical field [0001] The invention relates to the field of electrolytic copper foil production, in particular to electrolytic copper foil production equipment with cleaning components and a production process thereof. Background technique [0002] Copper foil is an important material for the manufacture of copper clad laminates and printed circuit boards. In the rapid development of today's electronic information industry, electrolytic copper foil is called the "neural network" of electronic product signal and power transmission. When the foil machine is working, the electrolytic copper foil deposited on the surface of the cathode roller rotates with the cathode roller. When exiting the anode tank, copper sulfate solution in the electrolysis area will adhere to its surface. Copper foil with copper sulfate solution attached to the surface must be subjected to subsequent surface treatment within 2-3 days, otherwise severe oxidation will occur on the surface, which will caus...
