How to judge the quality of a soldering flux?
Give me a break! Your question is very difficult...... What kind of soldering flux is good? A flux suitable for production needs is good! There are many kinds of soldering flux. According to the production process, there are three kinds of tin flux (hot air leveling), wave soldering flux and hand dipping flux. Their standards are different. The pH value, corrosion to copper, the proportion of halogen content, solid content, resistance welding surface insulation resistance, solvent extraction, odor, smoke volume, solution appearance is different. The guy who said before measuring the proportion, proportion should be 0.80-0.82, it is. The specific weight of tin spray flux is 1. Can you say it's not good? There are also IC rosin based soldering fluxes, some of which can reach 0.85......The landlord, because your problem is over, I can only answer, determine the flux is good or bad, it should be judged whether to meet the needs of production.Answered so much, Gaga points.
Specific gravity. The specific weight should be 0.80-0.82
Sticky tin stick is good, sticky, bad is bad! ~Very simple

According to the production process, there are mainly tin fluxes. Wave soldering flux, hand dipped flux, these three categories. Their standards are different. The pH value, corrosion to copper, the proportion of halogen content, solid content, resistance welding surface insulation resistance, solvent extraction, odor, smoke volume, solution appearance is different. Before the guy who said the proportion of the proportion of 0.80-0.82 should be measured.The specific weight of tin spray flux is 1. Can you say it's not good? There are also IC rosin based soldering fluxes, some of which can reach 0.85......To judge whether the flux is good or bad should be judged by whether it can meet the needs of production. The answer is for reference only
