There are several processes for reducing dross formation in a tin/lead solder pot. Dross is formed when molten solder on the surface of the solder pot or bath comes in contact with oxygen forming tin oxides. A thin film of dross in a solder pot is desirable as it slows down further oxidation of the solder as long as it is not detrimental to the integrity of the solder wave. Atmospheric conditions, humidity, soldering temperature, agitation of the solder and quantity of flux contribute to the production of dross.
