The influence of the substrate on the electroplating and filling holes is also negligible. The effect of the substrate on the filling of the plating is also not to be ignored. (1) Anode type. when the concentration of a particular type of ion is high, that ion will more likely to be discharged in electrolysis irrespective of its position in the electrochemical series. Main 3 effects of electric current are Heating, Chemical & Magnetism. Inorganic chemical components include copper (Cu :) ions, sulfuric acid and chloride. is the chemical separation of an ionic compound using a direct electrical current.. Key points in electrolysis Ionic compou nd in molten or aqueou s state. Factors. At present, the research on the plating hole is mostly limited to the whole plate plating, if taking into account the graphics plating hole, the cathode area will become very small. The overall process of electroplating uses an electrolytic cell, which consists of putting a negative charge on the metal and dipping it into a solution that contains metal salt (electrolytes) which contain positively charged metal ions. The spacing between the cathode and the anode is very important in the electroplating process, and the design of the different types of equipment is not the same. Electroplating is widely used in industries such as automobile, airplanes, electronics, jewelry, and toys.
