Abstract

Procédé permettant de souder des composants électroniques sur des panneaux de circuits imprimés. Les éléments à souder 23 sont placés dans une enceinte 11 comportant un liquide 13 qui est amené à ébullition pour fournir une vapeur saturée 27. Le liquide 13 est constitué par environ 95 % d'un solvant tel que l'octanol-1 ou l'éther monoéthyl glycol diéthylène, et par environ 5 % d'acide gras, tel que l'acide acétique ou l'acide héxanoïque. Les éléments 23 sont laissés pendant environ 1 minute dans l'atmosphère 27 afin d'effectuer l'opération de soudure proprement dite puis sont retirés de l'enceinte 11. Ce procédé est appliqué dans la technologie de fabrication de dispositifs semi-conducteurs.
