The important reason for humidity test in connector test


After the connector is shipped, there are many important links, such as production links, such as testing links. When we talk about the test link, we must not get around an important point, that is, the humidity test in the connector test link, which occupies a very important position. Because the humidity test can ensure the ability of the product to withstand higher humidity and cycle temperature, Konnra connector engineers focus on introducing you to the humidity test in the connector test link. For the humidity test, we will explain from two points, the first is what is the humidity test of the connector, and the second is how to test the humidity of the connector, the specific content is as follows:

First, what is the humidity test of the connector

Konnra connector engineers pointed out that since condensation on parts can cause failures, it is very important to understand the function of the connector group being used. Failures caused by humid environmental factors may appear in the form of corrosion of the coating and lead to reduced electrical performance. The humidity test takes this into consideration by setting the mating connector to a different temperature range of 25°C – 65°C and a relative humidity range of 90%RH – 98%RH within 10 days.

Second, how to perform the connector humidity test

To determine how the connector kit responds to the humidity test, the parts will pass, mating/unmating, IR/DWV and LLCR before and after exposure to moisture. Solder the connector kit to the appropriate test board, and then perform the initial baseline test. Afterwards, perform a humidity test on the parts indoors and then retest to determine whether they passed the humidity test. It should be noted that if the connector fails the electrical requirements of LLCR or IR/DWV, the connector is considered to have failed the humidity test. The standard for humidity testing by the regular connector manufacturers is usually EIA-364-31 "Humidity Test Procedure for Electrical Connectors and Sockets" as the test standard for humidity testing.
