Solder flux chemical composition
WebFeb 28, 2024 · What soldering flux does. Understanding flux requires comprehension of what it does. As with most things related to soldering, that begins with wetting forces. Solder flow is called wetting. When solder flows over a surface like a component lead, it is said to “wet” the surface. Failure to flow is non-wetting. WebVIGON EFM. VIGON EFM is a precision cleaning agent designed to remove flux residues from electronic assemblies in manual applications. The flux remover can also be used in explosion-proof spray-in-air equipment. VIGON® EFM is a mixture of halogen-free organic solvents. It dries fast and residue-free.
