Abstract

A common problem with molten solder stored in the solder pot of a wave soldering machine is dross formation. Dross formation results from oxidation of the molten tin/lead alloy solder on exposure to oxygen (air). The average percent solder that forms dross is 50%. Currently, there are no inerting systems in place specifically for the solder pot. The existing systems installed for inerting a wave solder oven and to reduce dross formation, are inert gaseous jets placed adjacent to the waves, and also inert gas flowing into the solder atmosphere of the oven.
