Abstract

La présente invention concerne un dispositif de montage de composants servant : à effectuer une opération d'alimentation pas à pas, dans laquelle une bande d'alimentation en composants (24) est alimentée à un pas prescrit après l'autre tandis qu'un film de recouvrement (30) est décollé de la surface supérieure de la bande d'alimentation en composants à l'aide d'un dispositif d'alimentation en bandes (23), et à chaque réalisation de l'opération d'alimentation pas à pas ; à aspirer, à l'aide d'une buse d'aspiration (27), un composant (26) situé dans un évidement de logement de composant (29) qui s'est arrêté en une position d'aspiration de composant prescrite ; et à monter le composant (26) sur un substrat de circuit (12), le composant situé dans l'évidement de logement de composant qui est arrivé au niveau de la position d'aspiration de composant suite à l'alimentation pas à pas étant imagé une pluralité de fois par en haut par un appareil de prise de vues (34), la pluralité d'images obtenues par l'imagerie effectuée une pluralité de fois étant traitées, la position du composant dans l'évidement de logement de composant étant identifiée en ce qui concerne chacune des images et une détermination de stabilité d'arrêt de composant étant réalisée de manière à déterminer, en fonction des résultats de traitement de la pluralité d'images, l'état de stabilité du composant dans l'évidement de logement de composant immédiatement après la réalisation de l'alimentation pas à pas.
