GB/T 2423.32-2008 "Environmental testing of electrical and electronic products - Part 2: Test methods, test Ta: wetting weldability" stipulates the test method for testing the weldability of electrical and electronic products by wetting weighing method. The standard specifies the test principle, equipment and material requirements, operation process and result evaluation standards. By quantitatively analyzing the wetting characteristics of solder on the surface of the sample, the weldability performance of the product is scientifically evaluated, which provides a technical basis for ensuring the welding mass and improving the electrical connection Reliability of the product.
