When soldering a component to a board, the solderability protection on the component combines with the solderability protection on the board and the solder to form an alloy. This alloy is unique for that combination of solder and solderability protec

Hi Dave sorry not been back the Tin/P regenerator is controlled amounts of Phos additive that metallurgically reduces the dross. We do not recommend chemical methods for dross reduction as many salts/chemicals used could be hygroscopic in nature and

SN100C contains no phosphorus. It has a dross rate equal or lower than tin-lead solder, where as SAC drosses at 2 to 3 times the dross rate of tin-lead solder. Addition of solder dross inhibitors, such as phosphorus, can be effective inhibitors of
