Abstract
When dross is removed from a molten-solder reservoir, a substantial amount of molten solder is often removed with the dross. This molten solder can be separated from the dross and returned to reservoir via a conduit for reuse. Additionally, a skimmer for removing the dross from the reservoir includes a skimming plate pivotally attached to a displaceable structure; a stop is provided to restrict the degree to which the skimming plate can pivot so that the skimming plate will not pivot more than 90° from vertical to enable the skimming plate to dig into the dross and collect dross when the displaceable structure is displaced toward on outlet of the reservoir. Further still, the displaceable structure of the skimmer can be controlled via a computer control system storing software code instructions for a motor to extend and retract the displaceable structure such that the skimming plate extends to a position further from the outlet port of the reservoir with each displacement cycle.
