Quality analysis of phosphorous copper ball for acid copper-plated anode

If the phosphorus content of the phosphorus anode is low, the anode film of the phosphorus anode is thin and less before passivation, the copper plating solution has a valence copper ions, the copper ions rise sharply, resulting in the anode film on the surface of the phosphorus copper anode is yellow or greenish yellow film phenomenon. A, from the coating surface quality to determine the quality of phosphor copper ball if the phosphor copper anode phosphorus content is low, passivation before the anode film of phosphor copper anode thin and less, copper plating solution has a valence copper ions, the copper ions rise sharply, resulting in the anode film of phosphor copper surface is yellow or green yellow film phenomenon.

If there is a layer of brown film under the black film on the surface of the phosphor copper anode, the impurity content in the phosphor copper anode exceeds the standard. Generally, the phosphor copper anode produced with mixed copper will appear this passivation phenomenon. If the phosphorus copper anode passivation caused by the quality of the phosphorus copper anode itself, the phosphorus copper anode should be replaced. Two, the coarse copper grain is too heavy and colloidal gel can not support the formation of anode mud, resulting in rough electroplating, and at least 3 months to clean and replace the anode bag 1 times. Small grain phosphorus can prevent fine copper particles from falling off the anode. The use of high quality phosphorus copper anode, phosphorus distribution is very uniform, fine crystalline particles, compact structure, "black phosphorus film" is not thick, not thin, moderate binding force, reliable quality, effectively prevent the formation of univalent copper ions. Due to the fine copper crystallization, moderate phosphorus content and uniform distribution, the anode mud is very little, the anode bag is usually cleaned for more than half a year, which not only improves the production efficiency of electroplating, but also saves the anode bag and other ancillary raw materials. For any plating operation, a good anode must meet the following requirements: less impurity content, fine grain, regular; Acid copper plating system requires a uniform distribution of 0.04%-0.065% phosphorus content; Surface free of oil, oxidation, burr. The anode must be ready for immediate use and have a high operational performance without concern for trouble. The use of high quality copper anode for electroplating manufacturers to bring benefits: improve the yield, reduce production costs, improve production efficiency and physical properties of the plating industry to meet the increasingly high technical requirements, to meet its development trend.
