A non-toxic, non-corrosive foaming soldering flux (14) comprises citric acid and water, together with at least one foaming agent. The foam is fast-breaking, dissipating almost immediately. Such a fast-breaking foam is novel in an aqueous-based flux. The unique flux of the invention produces solder joints of high metallic luster and excellent quality. Disposal presents no health hazards, and clean-up of flux residues is accomplished using only water and, optionally, a surfactant.
Flux de brasage tendre (14) moussant, non toxique et non corrosif, composé d'acide citrique, d'eau et d'au moins un agent moussant. La mousse formée est très peu stable et se disperse presque immédiatement, ce qui constitue une nouveauté dans le domaine des flux aqueux. Ce flux permet de réaliser des joints d'excellente qualité, présentant un bel éclat métallique. Les résidus ne sont pas nocifs et peuvent être nettoyés à l'eau claire ou additionnée d'un tensioactif.
