Abstract

PROCEDE DE POSITIONNEMENT ET D'INSPECTION OPTIQUE D'UN OBJET La présente description concerne un procédé d'inspection optique d'un circuit électronique (12) comprenant au moins un profilomètre (24) comprenant un projecteur (P) projetant sur le circuit électronique un faisceau lumineux dont l'épaisseur est inférieure à 200 µm et au moins un capteur d'images (C) pour l’acquisition d'images du circuit électronique. Le procédé comprend le transport du circuit électronique par un convoyeur (14) selon une direction de convoyage (X), la commande de l'arrêt du convoyeur après que le circuit électronique est détecté par le profilomètre à une première position et l'utilisation du profilomètre pour la détermination d'une image tridimensionnelle du circuit électronique.
