Abstract

Ce dispositif de gestion de maintenance gère le travail de maintenance effectué sur un élément lié à l'imagerie qui comprend au moins un élément parmi : un motif de référence fourni à un dispositif de montage qui monte un composant sur un substrat ; et une unité d'imagerie qui image le motif de référence. Ce dispositif de gestion de maintenance comprend une unité de détermination qui détermine si un travail de maintenance est nécessaire pour l'élément lié à l'imagerie qui est l'un ou l'autre du motif de référence et de l'unité d'imagerie, sur la base d'une valeur d'évaluation obtenue à partir des résultats d'imagerie à partir de l'imagerie effectuée par l'unité d'imagerie pendant un traitement d'étalonnage qui est effectué périodiquement afin de maintenir la précision de montage du dispositif de montage.
