Abstract

La présente invention se rapporte à un appareil permettant de monter un élément électronique, l'appareil pouvant supprimer les dégâts causés à l'élément électronique, la diffusion de la brasure et les dégâts causés à un substrat et permet le soudage de l'élément électronique à une carte de circuit imprimé en un temps plus court que par le passé. Cet appareil (100) destiné à monter un composant électronique (112) monte un élément électronique (108) sur une carte de circuit imprimé (122) qui comporte un substrat flexible (122A) et un schéma de câblage (122B) agencé sur le substrat, l'appareil destiné à monter un composant électronique comprenant : un dispositif d'alimentation (102) destiné à fournir la brasure (104) sur le schéma de câblage (122B) de la carte de circuit imprimé (122) ; un dispositif de placement (106) destiné à placer l'élément électronique (108) sur la brasure (104) ; et un laser (110) destiné à diriger de la lumière qui présente une longueur d'onde centrale d'émission de lumière dans une plage comprise entre 700 et 1100 nm depuis le côté surface arrière (124) de la carte de circuit imprimé vers la brasure (104) sur laquelle est placé l'élément électronique (108), la lumière passant à travers le substrat (122A) et atteignant le schéma de câblage (122B), chauffant le schéma de câblage (122B) et provoquant la fusion de la brasure (104) et soudant l'élément électronique (108) à la carte de circuit imprimé (122).
