The central role of humidity testing for connectors?

I. What is the central role of humidity testing for connectors? Many electronic products experience multiple climates during operation and storage, in which case humidity testing of connectors is often used to determine the ability of the product to withstand higher humidity and cycling temperatures. Since condensation on parts can lead to failure, it is important to understand the functionality of the connector set being used. Failure due to humid environmental factors can come in the form of corrosion of the plating and lead to degradation of electrical performance. And the humidity test takes this into account by setting the mated connectors at different temperature ranges from 25°C - 65°C and a relative humidity range of 90% RH - 98% RH over a period of 10 days.In order to determine how the connector set responds to the humidity test, before and after exposure to moisture, the parts will be passed, paired/unpaired, IR/DWV and LLCR. solder the connector kit to an appropriate test board and then perform an initial baseline test. The parts are later humidity tested indoors and then retested to determine if they pass the humidity test. Be aware that if a connector does not pass the electrical requirements for LLCR or IR / DWV, the connector is considered to have failed the humidity test. Proper connector manufacturer's humidity tests use the standard usually EIA-364-31 "Humidity Test Procedure for Electrical Connectors and Receptacles" as the test standard for humidity testing.
