Abstract

In a method of dry process fluxing at least one surface of a metallic article, the surface to be fluxed is treated with a plasma at atmospheric pressure of a gaseous mixture comprising hydrogen and optionally at least one inert gas. The invention also concerns an apparatus, particularly for practicing the process, as well as a process for soldering or plating.
