Studies on Flux Action of Soldering (Report II) : Amine Hydrochloride
Search this article
In this report, aniline hydrochloride flux action of soldering was studied on the relation between the reaction of flux with base metal (Cu) or with Sn-Pb alloy solder and spreading phenomenon. The flux action of aniline hydrochloride may be considered as follows: Molten aniline hydrochloride reacts with copper of base metal to give CuCl_2 and copper complex, which react with molten Sn-Pb alloy solder to give metal copper. Copper dissolves immediately into molten solder and the thin Cu-rich layer at the outer surface of molten solder is formed. The wetting of Sn-Pb alloy solder on copper plate is improved by the reaction and the dissolution of Cu into molten solder. So, Sn-Pb alloy solder spreads well over copper plate.
