Abstract

Cette invention concerne une technologie avec laquelle des items d'inspection et des normes d'inspection dans des inspections de substrat et analogues peuvent être optimisés pour chaque pièce, ce qui permet de gérer la qualité d'items d'inspection et/ou de normes d'inspection pour chaque pièce. Ce procédé d'inspection implique l'utilisation d'un programme d'inspection pour effectuer l'inspection d'articles sur lesquels des pièces ont été Installées, et comprend : une étape de réglage (S101) à laquelle des informations d'inspection comprenant des items d'inspection et/ou des normes d'inspection pour des pièces dans des inspections sont définis pour chaque pièce; et une étape d'évaluation (S106) à laquelle la qualité des articles est évaluée à l'aide du programme d'inspection. Les informations d'inspection comprennent en outre des informations de niveau de qualité d'inspection qui sont un indicateur de la fiabilité desdites informations d'inspection. À l'étape de réglage, les informations d'inspection sont réglées sur la base d'un groupe de données de numéro de pièce qui est fourni pour chaque numéro de pièce des pièces et est mis à jour avec chaque changement d'informations d'inspection. À l'étape d'évaluation, la qualité de chaque pièce est évaluée sur la base d'informations d'inspection acquises en référence au groupe de données de numéro de pièce.
