scope:

This handbook addresses semi-aqueous cleaning of electrical/electronic assemblies, parts and application tools after soldering. Semi-aqueous cleaning or hydrocarbon surfactant cleaning is a process in which flux residues and other contaminants are removed from printed wiring assemblies by first washing the assemblies in an organic solvent and then rinsing the organic solvent from the assemblies with water. The other parts and application tools are similarly cleaned using this same process or the emulsion variant of it. The semi-aqueous process specifically does not include cleaning with aqueous solutions of saponifiers or detergents.
