Copper sulfate pentahydrate plays an extremely important role in PCB electroplating. The quality of acid copper plating directly affects the quality of electroplated copper layer and related mechanical properties, and has certain influence on subsequent processing. Therefore, how to choose high-quality high-purity copper sulfate and control The quality of the good acid copper plating process is an important part of PCB plating.
In the electronic printed circuit board manufacturing industry, the acid copper plating process is used to thicken the electroless copper plating layer. Due to the extremely high quality and excellent dispersing ability of the board plating, it is extremely sensitive to various metal impurities (such as iron, zinc, lead, tin, antimony, etc.) and organic impurities in the plating solution. Copper sulfate, as the main salt in the acidic copper sulfate plating bath, the quality of the copper sulfate must be fully guaranteed, and materials of the above grade of plating are usually used. The role of copper sulfate is to ionize copper ions in an aqueous solution, and copper ions are electron-deposited on the cathode to deposit copper plating. The use of high-purity refined copper sulfate can minimize the loss of various metal impurities and organic impurities in the plating solution, thereby effectively preventing pinholes, grit, blackening, fogging and the like of the plating layer, and ensuring plating. The uniformity of the thickness distribution of the plate surface and the deep plating ability of the deep hole and the small hole can help improve the physical properties of the coating, such as ductility and tensile strength.
It can be seen that high-purity copper sulfate has broad market prospects in the field of PCB plating.
