Introduction

As a key supporting material in the soldering process, solder flux has a decisive influence on the quality of soldered joints: In the implementation of the strong foundation project, the national science and technology major project "core electronic devices, high-end general-purpose chips and basic software products" and "super large-scale Technology research and development of core electronic devices, high-end chips and integrated circuit complete sets of technology in the "Special Project for Molded Integrated Circuit Manufacturing Equipment and Complete Sets of Technology" Among them, solder flux is the key basic material, and it is of great significance to formulate the test method standard for its quality performance evaluation: Since:2001, my country has successively promulgated and implemented "Tin-Lead Soldering Materials", "Lead-Free Soldering Materials", "Solder Flux Classification and Performance Requirements" and "Solder Soldering Materials": As an important component of the solder, solder flux is not only important for the solderability and processability of the solder It is also critical to the environment, reliability of solder joints and applications: GB/T 38265 "Solder Flux Test Method" is a General test method standard, it is proposed to consist of the following parts: --- Part 1: Gravimetric method for determination of non-volatile matter content; --- Part 2: Boiling point method for the determination of non-volatile matter content; --- Part 3: Determination of acid value by potentiometric titration and visual titration; --- Part 5: Bronze mirror test; --- Part 6: Determination of halide (excluding fluoride) content; --- Part 8: Determination of zinc content; --- Part 9: Determination of ammonia content; --- Part 10: Test methods for the spreading of the wetting properties of solder fluxes; --- Part 11: Solubility of flux residues; --- Part 13: Determination of flux spatterability; --- Part 14: Evaluation of the adhesiveness of flux residues; --- Part 15: Copper corrosion test; --- Part 16: Wetting balance method for wetting properties of solder flux; --- Part 17: Surface insulation resistance comb brush test and electrochemical migration test of flux residues: The method used in this document is used to qualitatively evaluate the spatterability of the solder flux: This method has the advantages of simple operation, strong applicability, accurate and reliable results, etc: At present, it has become an important detection method in solder flux products: Soldering flux test method Part 13: Determination of flux spatterability

1 Scope

3 Terms and Definitions

There are no terms and definitions that need to be defined in this document:

4 Principles

Place a certain amount of liquid flux sample on the steel sheet test piece, heat the test piece in the solder bath, and visually inspect the surface of the test piece for softness: Flux spatterability:

5 Instruments and equipment

5:1 Solder bath The cross section of the solder bath is rectangular, the size is about 150mm×100mm, it can accommodate at least 4kg of solder, and the liquid level of the solder is soft: The upper edge of the solder bath is not more than 5mm, and the temperature can be maintained at (400±10) ℃: 5:2 Specimen The steel sheet should meet the requirements of GB/T 5213, cut from a 1mm thick non-alloy steel sheet, and the size of the test piece should be softer than the corresponding The length and width of the solder bath (5:1) are 10 mm larger: 5:3 Silicon carbide abrasive cloth Silicon carbide emery cloth 180 mesh:

6 Test steps

6:1 Adjust the temperature of the solder bath to (400 ± 10) ℃, and ensure that the height of the solder liquid level is (4 ± 1) mm lower than the upper edge of the solder bath: ......
