Title
(EN) METHOD OF PRINTING AND PRINTING MACHINE
(FR) PROCEDE D'IMPRESSION ET MACHINE A IMPRIMER
Abstract
(EN)
Screen printing apparatus including two cameras for effecting alignment of a stencil with a PCB or circuit board (20). The circuit board (20) is mounted on a table (12) movable relative to a stencil (26) fixed in position on the apparatus. The table is able to move in a first direction between a circuit board loading position and a print position. A first camera (11) for viewing the circuit board (20) is mounted on the apparatus for movement in a direction transverse to the first direction. A second camera (13) for viewing the stencil (26) is mounted on the table (12) and is mounted for movement in a direction perpendicular to the first direction. Thus each camera (11,13) is effectively able to move in X any Y axes relative to the object (20,26) it views. By means of viewing fiducial marks on the circuit board (20) and the stencil (26) with the cameras as the table (12) moves from the load position to the print position, a control unit of the apparatus ascertains the relative positions of the circuit board (20) and the stencil (26), aligns the stencil and circuit board and then prints solder paste onto the circuit board (20) in a pattern determined by the stencil (26).

La présente invention concerne un appareil de sérigraphie comprenant deux caméras qui permettent d'aligner un pochoir par rapport à une carte à circuit imprimé (20). La carte à circuit imprimé (20) est montée sur une table (12) pouvant être déplacée par rapport à un pochoir (26) fixé en position sur l'appareil. La table est capable de se déplacer dans une première direction, entre une position de chargement de carte à circuit imprimé et une position d'impression. Une première caméra (11) permettant de visualiser la carte à circuit imprimé (20) est montée sur l'appareil de façon qu'elle se déplace dans une direction transversale par rapport à la première direction. Une deuxième caméra (13) permettant de visualiser le pochoir (26) est montée sur la table (12) de façon qu'elle se déplace dans une direction perpendiculaire à la première direction. De la sorte, chaque caméra (11,13) est effectivement capable de se déplacer dans les axes X et Y par rapport à l'objet (20,26) qu'elle permet de visualiser. En visualisant le pochoir (26) et des repères d'alignement sur la carte à circuit imprimé (20) à l'aide des caméras au fur et à mesure que la table (12) se déplace de la position de chargement vers la position d'impression, une unité de commande de l'appareil vérifie les positions relatives de la carte à circuit imprimé (20) et du pochoir (26), aligne le pochoir et la carte à circuit imprimé et imprime ensuite de la soudure en pâte sur la carte à circuit imprimé (20) selon un motif déterminé par le pochoir (26).
