Abstract
A mixture of a dye including one or more water soluble fluorescent dyes and a water soluble solder flux provides simple optical inspection under ultraviolet illumination with simple apparatus. The optical inspection is thus made highly sensitive to the presence of residual water soluble flux after washing and highly specific to the water soluble flux with which the dye is mixed. Thus, optical inspection can assure that all water soluble flux is removed to avoid subsequent corrosion while providing the possibility of leaving so-called 'no clean' fluxes in place.
