<p>A vessel contains a volume of solder (14) and a volume of electronic liquid (16) floats on the solder. A heater (18) heats the electronic liquid to generate a zone (20) of saturated vapor and to transfer heat to the solder across the interface therebetween. Hot saturated vapor is drawn downwardly through a manifold (48, 52) in the solder to heat the solder. Molten solder is applied to work product which is conveyed through the saturated vapor zone.</p> |
