Scope

This part of GB/T 4909 specifies the test equipment, sample preparation, measurement procedures, test results and evaluation, etc. for the solderability test of the bare wire solder ball coating. This section is applicable to test the wettability of the surface of tinned copper wire by molten solder, which is expressed by a specific time. The method in this part is to use the sample to divide the solder ball of molten solder into two halves, and measure the time required for the sample to cut the solder ball until the solder flows around the sample and covers the sample. This time indicates the solderability of the sample. This section should be used together with GB/T 4909.1-2009.
