　　Why can board-to-board connectors be tested in a salt spray environment?

　　The salt spray environment mainly refers to the application environment of medical device connectors and electric vehicle connectors and underwater application equipment. Generally, the salt spray environment refers to the salt spray environment formed by 5% salt solution. Usually, the equipment and parts in the environment such as salt exposed to the sea and land are effectively evaluated in this environment, not the real environment. The normal exposure time is 48 hours to 96 hours.

　　Salt spray test is usually used in the underwater environment, usually used to evaluate the corrosion resistance of the metal connector shell (such as confirming the corrosion protection effect of the nickel plating on the surface of the zinc alloy die casting), checking the DWV and insulation resistance, and confirming the performance of the exposed parts , Confirm that the enclosure seal is effective.

　　The salt spray test is also used for the evaluation of automobile connectors. When cars and trucks are walking, the position of these board-to-board connectors may be exposed to water splashed by tires, especially after snow in the northern winter, add salt to accelerate the snow on the road melt. These connectors are usually subjected to salt spray testing to verify corrosion resistance. The verification standard is also to check the reliability of the contact resistance, not to check the appearance to evaluate. These connectors are usually used with sealing rings to improve their salt spray resistance.
