Detailed Description
Our copper sulfate is featured with its high purity. The purity of Model Cu-10 is about 99.5%. It is mainly used in IT industry or for science research because the impurity contents of Fe , Ca, Pb, As, Co, Ni, are lower than the copper sulfate specification of chemical agent in GB665-88 standard. Especially in the PCB manufacturing industry, using high-purity copper sulfate will avoid organic and metal impurities taken into the electroplating bath, thereby preventing the problems of pits, marks, darkness and mist. It ensures a well-proportioned surface and improves the tactility of the board and the strength of resisting haul. Composition: CuSO4. 5H20 > 99 % Cu ≥25.20 Fe ≤ 10 ppm As ≤ 5 ppm Ca ≤ 5 ppm Zn ≤ 10 ppm Cl ≤ 10 ppm Pb ≤ 10 ppm Ni ≤ 5 ppm PH: 3.5 - 4.5
