Un dispositif de montage de composants est pourvu : d'une buse d'aspiration qui permet de maintenir un composant électronique par aspiration ; d'un dispositif d'imagerie qui permet de capturer une image de la buse d'aspiration depuis le côté de la buse d'aspiration ; d'une unité de détermination de largeur qui permet de mesurer la largeur de la buse d'aspiration dans une direction orthogonale à la direction verticale à partir de l'image capturée de la buse d'aspiration capturée par le dispositif d'imagerie ; d'une unité de détermination d'anomalie qui permet de déterminer une anomalie de la buse d'aspiration à partir de la largeur de la buse d'aspiration mesurée par l'unité de détermination de largeur.
