Abstract
L'invention concerne un procédé et un appareil de soudage par laser. Des dispositifs optiques focalisent simultanément des faisceaux laser cohérents sur des soudures aux extrémités opposées d'un composant L'énergie ainsi produite fait refondre la soudure, et les deux soudures sont formées simultanément au refroidissement. L'invention s'applique notamment au soudage des condensateurs plats sur des plaques de circuits imprimés.
