Abstract

L'invention concerne un appareil de transfert de composant électronique et une unité de conditionnement en bande alvéolée empêchant facilement et de manière plus fiable qu'un composant électronique soit conditionné de manière incorrecte lors de son conditionnement dans une bande alvéolée. L'appareil de transfert de composant électronique et l'unité de conditionnement en bande alvéolée détectent la position d'une alvéole de la bande alvéolée destinée à loger le composant électronique et, en fonction des résultats de la détection, un décalage positionnel de l'alvéole est détecté. Un moyen de déplacement permet de déplacer la bande alvéolée, celle-ci étant déplacée dans le sens de la largeur et dans le sens de la longueur de façon à corriger le décalage positionnel ainsi détecté.
