Control method of electric current density in electroplating
专利汇可以提供Control method of electric current density in electroplating专利检索，专利查询，专利分析的服务。并且PURPOSE: To enable to control the electric current density, by using the potentiostat as electrolytic power source at the electroplating.
CONSTITUTION: Potentiostat used as a constant electric potential electrolytic apparatus, is constructed by the control part composed of the potential set up part 1 and the direct current amplifier 2 and the operation part composed of the electric power amplifier 3. Terminal drawn out from the above apparatus, is connected with the anode 4, the cathode 5 of the plating liquid 6 and the reference electrode 9. Normally, calomel electrode is used for the electrode 9 and the electrode 9 is dipped in the saturated potassium chloride solution 8. The electrode 9 is connected with the liquid 6 by the ion transmission solid body 7. When the cathode potential is set up as Es at the potential set up part, each part of control and operation is acted so as to be the potential E between the cathode 5 and the electrode 9 kept at Es. Accordingly, the cathode 5 is kept at a constant potential for the electrode 9 and also, current density is kept constant because the potential and current density are corresponded to 1:1. Thus, the current density is made possible to keep constant in the plating.
