Advantages of gold contacts over tin contacts

As a precious metal, gold will not react with other materials, and gold will not oxidize or change color in the atmosphere, and it will be durable for a long time in harsh environment, so it is very suitable to contact with the coating layer. Silver plating has the best conductivity, but the chemical properties of silver are unstable, which is easy to produce silver sulfide, thus affecting the contact discoloration, welding and other properties of the contact; general connection Because tin is cheaper and has anti-corrosion function, the texture of tin is relatively soft, which is conducive to the coordination between the plug and socket. However, due to the soft texture, it is easy to wear the electroplating surface after several times of plugging and plugging, resulting in deformation of the contact end and failure to reach the designed contact force.
