What is board-to-board connector salt spray testing?

I. What is board-to-board connector salt spray testing? Salt spray testing is commonly used for connectors in underwater environments and is often used to evaluate the corrosion resistance of metal connector housings (e.g., to verify the corrosion protection of nickel plating on the surface of zinc alloy die castings), and to determine that housing seals are effective by checking DWV and insulation resistance to confirm the performance of exposed components. Salt spray test is also sometimes used for automotive connector evaluation, when the car or truck travel, these board-to-board connection connector is located in the location may be exposed to components to the splash of water on board the ship, especially in the northern winter after the snow, the highway will be applied to accelerate the snow melt, these connectors in general to carry out a salt spray test to verify the corrosion resistance, the verification of the standard is also a test of the reliability of the contact resistance, and Not by checking the appearance of the evaluation, very often these connectors to be used together with the seal to improve its salt spray resistance.
