What is the concept of tinning copper bars

  Traditional tin-plated copper bars use the hanging tin plating method. The copper bars are hung with a lifting tool, and they are partially or wholly placed in the plating bath electroplating solution, and a layer of tin plating is plated on the surface of the copper bars. This process is used in electroplating. During the process, the contact point of the copper bar hung by the spreader and the power connection is fixed, and the current density around the electrical connection contact point is as the farther away from the fixed electrical contact, the smaller the corresponding current density, resulting in The electroplating layer on the surface of the copper bar is uneven, and the surface is uneven. Moreover, as the electrical connection time of the copper bar increases, the surface temperature of the electrical connection contact point of the copper bar rises sharply. The higher the temperature of the electrical connection contact point of the copper bar, the higher the temperature. The smaller the current density on the surface, the lower the efficiency of electroplating; in this process, the electroplating tank is in a smooth state. When the copper row is electroplated, the plating solution in the tank is heated and volatilized. Space and working environment are poor, which seriously affects the environment, and acid mist is harmful to health.  In view of the shortcomings of the existing tinned copper rack plating technology, the copper row manufacturer invented the “a method and equipment for continuous walking and tinning of copper rows”, which moves the copper row to be plated from the electroplating tank continuously and at a uniform speed. It can be electroplated at a higher current density, which not only improves the efficiency of tinning, the surface of the tin-plated copper bar is uniform, smooth, flat, meticulous, strong in adhesion, and strong in corrosion resistance. Moreover, the copper bar in this method is continuously tinned The equipment can purify the harmful exhaust gas such as acid mist generated in the plating solution, which does not pollute the environment and improves the working environment of workers.  Yueqing Renhe Electronics Co., Ltd. is a professional copper bar manufacturer in Zhejiang, focusing on the production, research and development of new energy electric vehicle battery copper bar connection, electrical connection copper bar, braided copper bar, flexible copper bar connection, cable connection and insulating protective cover And sales.Products comply with EU environmental protection, UL flame retardant, ISO9001 management system certification requirements.
