Abstract

Bec à souder produisant une onde de soudure régulière sans turbulence. Le bec fournit au moins un jet d'air servant à éliminer les rubans et les ponts de soudure se formant sous les plaques de circuits imprimés et d'autres éléments. Les plaques sont déplacées vers le haut dans le sens de la propagation, et après qu'elles ont été exposées à l'onde de soudure, une lame d'air projette un gaz non oxydant avec suffisamment de force pour éliminer le métal excédentaire. Le soudage peut être effectué dans un milieu contenant un gaz non oxydant, par exemple un gaz rare ou un gaz réducteur, et l'utilisation d'ondes d'une fréquence inférieure à la fréquence ultrasonore peut faciliter le soudage.
