Abstract
An apparatus for wave soldering component leads to a conductor on a printed circuit board surface includes a fountain for forming a standing wave of hot molten solder. A pool of hot oil having a specific gravity lower than the solder floats in a depression in the surface of the solder adjacent to the standing wave. A printed circuit board whose surface is to be soldered is passed through the crest of the molten solder standing wave and then while the solder adhering to the component leads and conductor is still molten, into contact with the pool of hot oil.
