Reasons for the discoloration of the silver layer of copper beryllium reeds-beryllium copper reed manufacturers

Dongguan Precision Electronic Technology Co., Ltd. was established in 2008 and is located on the ferry road of Peihouwei Group, Renzhou Village, Shatian Town, Dongguan City, Guangdong Province. It is a precision stamping processing factory. Specializing in the production and processing of metal shrapnel, beryllium copper reed, stainless steel shrapnel, hardware terminals, various small hardware components. The company has a variety of advanced automated mechanical equipment and product testing equipment, strong technical force, has a strong strength in the production of small precision hardware accessories! Silver-plated beryllium copper reeds can increase conductivity, improve solderability, and can be used as a decorative effect. However, the silver layer is affected by certain factors, which can cause discoloration and reduce the performance of the workpiece. Although the silver coating has high chemical stability, it is easy to corrode and change color in the atmosphere, especially in the atmosphere containing industrial harmful gases such as H2S, SO2, Cl2, CO2, NOx, etc., from silver white, light yellow, brown to black, etc. . Under the influence of high temperature, this kind of corrosion and discoloration is more severe. H2S and SO2 in the air contact the silver surface to form Ag2S, which is the main cause of discoloration. In the silver electroplating operation, the workpiece is not cleaned, the metal impurities, organic matter in the plating layer, rough plating layer, high porosity, etc. will cause corrosion of the micro battery, which will cause the silver layer to quickly change color. The discoloration of the silver coating not only affects the appearance of the coating, but also reduces the electrical conductivity and deteriorates the weldability. When the silver layer is electroplated in the processing of beryllium copper reeds, effective anti-tarnish treatment must be taken to ensure the quality of the silver layer.
