solder flux
5.The analysis results indicate that the correlative influence factors to the technological capabilities of electronic solders include the composition and purity and chemical uniformity of solder alloy, the composition and properties of mother materials and their clean level on the surface, the surface tension of liquid state solders, the temperature and atmosphere in soldering and the activity of flux, the chemical composition and structure and properties of the surface film of melting solders, and so on.
