This standard specifies the test method for the weldability of bare wire platings by solder ball method, and describes the test equipment, sample preparation, measurement procedures and evaluation standards in detail. It is suitable for testing the wetting characteristics of tinned copper wires in molten solder, and provides key time indicators to evaluate the weldability of platings. This standard is of great significance to ensure the welding mass and reliability of wires and cables, and should be used in combination with GB/T 4909.1-2009.
