Abstract(in English) | This paper describes a reflow soldering process not requiring the use of flux.Initially,we developed a process in which an argon- atom sputter-etching techniques employed to clean the surface,and reoxidation is prevented by carrying out aligning,mounting,and reflowing in an inert gas in a vacuum chamber.Then,for purposes of simplification,we developed a more convenient process in which, following the surface cleaning,the aligning and mounting are done in an atomosphere of ordinary air.This causes the reoxidation on surfaces activated by sputter-etching to be approximately the same both in a vacuum and in an air at room temperature.The thin oxide film is easy to break by volume expansion when it is melted.This allows that solder can wet.The basic characteristics and self- alignmentability were examined. |
