　　There are obvious differences in appearance, performance and application between bright tin and matte tin for pins and sockets.

　　From the appearance point of view, the surface of the pins and sockets plated with bright tin presents a bright silver color with high gloss. This high gloss appearance makes it widely used in some electronic products with high requirements for appearance. The surface of matte tin presents a matte gray color with low gloss. The appearance of matte tin is relatively low-key and more suitable for application scenarios that do not want to be too dazzling.

　　In terms of performance, bright tin has good conductivity and solderability. Its smooth surface helps the smooth passage of current and reduces contact resistance. At the same time, bright tin can blend well with solder during welding to form a strong welding connection. However, the hardness of bright tin is relatively low and it is easily worn during the plug-in process. Matte tin has higher hardness and wear resistance and can withstand more plug-in times. The surface of matte tin is relatively rough, which enables it to form a stable oxide film when it comes into contact with air, thereby improving its corrosion resistance. However, the conductivity and solderability of matte tin are slightly inferior to those of bright tin.

　　In terms of application, bright tin is often used in some occasions with high requirements for conductivity and solderability, such as internal connections of electronic equipment. Matte tin is more suitable for applications that require high wear resistance and corrosion resistance, such as automotive connectors, industrial equipment, etc. In addition, the matte appearance of matte tin also makes it used in some occasions that need to avoid reflection, such as military equipment, aerospace and other fields.
