Abstract
The invention provides an apparatus that separates solder from solder dross, comprising first and second rolls and a fixture. The first roll has a substantially cylindrical surface and is rotatable about a first longitudinal axis. The second roll has a substantially cylindrical surface and is rotatable about a second longitudinal axis parallel to the first longitudinal axis. The fixture is coupled to the first and second rolls and spaces the second roll apart from the first roll by a first distance, such as 0.001 to 0.015 inches, the first distance sufficient to separate a solder-dross mixture directed between the first roll and the second roll into a liquid solder and a dross powder when the first and second rolls are rotated in opposite directions.
