Why should the connector be tested in a salt spray environment

Salt spray test is usually used in underwater environments and is usually used to evaluate the corrosion resistance of metal connector shells (such as verifying the corrosion protection effect of the nickel plating on the surface of zinc alloy die castings), and confirm the exposure after DWV and insulation resistance The performance of the parts determines that the housing seal is effective.

The salt spray test is sometimes also used for the evaluation of automobile connectors. When a car or truck is walking, the location of these board-to-board connectors may come into contact with water splashing on the tires, especially after snow in the northern winter, on the highway. Apply salt to accelerate the melting of the snow. These connectors are generally subjected to salt spray testing to verify their corrosion resistance. The verification standard is also to check the reliability of the contact resistance, not to evaluate it by checking the appearance. Many times these connectors are used with seals to improve its salt spray resistance.
