Abstract
A flux concentration analyzer system based on an ultraviolet photometer is described. It is used successfully online in a foam fluxer during assembly of printed circuit boards. The system provides solvent regulation for low-solids fluxes with greater precision than control mechanisms based on measurements of the specific gravity ratio
