Scope: This document specifies three quantitative determination methods for the content of ionic halides in solder and a qualitative analysis method for ionic halides, including principles, reagents, equipment, test procedures, test data processing, expression of test results, and precision. degrees, test reports, etc. Method A in this document is applicable to Type 1 and Type 2 solder fluxes defined in GB/T 15829, and is used as a reference method for solder fluxes with a halide content of 0.05% to 2% (mass fraction) in non-volatile substances. Method B in this document is applicable to the determination of the total content of halides (excluding fluorides) in type 212 and type 311 solder defined in GB/T15829. Method C in this document is applicable to type 321 water-soluble solder containing phosphate as defined in GB/T 15829. Method D in this document is applicable to the qualitative analysis of ionic halides in all types of solders.
