ABSTRACT:
An improved method and apparatus restricts or limits dross formation in a soldering apparatus where liquid solder overflows such as wave soldering and the like. The improvement comprises a solder receiving tray positioned beneath at least a portion of liquid solder falling from an overflow or solder wave to a reservoir and a level control means limits the maximum solder level in the tray above a dynamic solder level in the reservoir, the solder level in the tray being a predetermined distance below the overflow to limit dross formation thus restricting dross recirculation.
