Abstract

Les composants de microcircuit comprennent un corps et une électrode dont les surfaces respectives sont faites de matériaux différents et présentent des caractéristiques superficielles différentes. C'est pourquoi l'algorithme de vision de la surface doit être différent en fonction de la surface considérée. Par suite de ces différences superficielles et de critères d'inspection distincts, il faudrait utiliser deux machines d'inspection différentes, ce qui est potentiellement coûteux. Avec ce nouveau système d'éclairage, il est possible d'inspecter deux surfaces différentes ou plus avec un seul et même système.
