Abstract
A tunnel enclosure has a fluid barrier curtain at an entry and an exit and provides an apparatus for soldering an element. The fluid barrier curtains permit an additive, such as a soldering aid or the like to be included with the fluid at the curtain. More than one zone permits different temperatures or gas atmospheres and elements are passed from zone to zone with fluid barrier curtains between. A process for soldering comprises conveying an element into an enclosed zone through an entry containing at least one fluid barrier curtain, with an additive added to fluid in the curtain, heating and soldering the element in the zone, and conveying the element from the enclosed zone through an exit containing at least one fluid barrier curtain.
