Patent

CA 2393058

A method of manufacturing a printhead assembly (10) includes selecting a micromolding sub-assembly (24), the sub-assembly (24) comprising a printhead chip (18), a flexible printed circuit board (PCB, 54) and a micromolding (26). The micro-molding sub-assembly (24) is attached to a cover molding (28) to form a print module (12). An ink reservoir sub-assembly (16) is formed and a plurality of the printhead modules (12) are attached to the ink reservoir sub-assembly (16) in end-to-end relationship. Ink is charged into the reservoir sub-assembly (16) and the completed assembly is tested.

L'invention concerne un procédé de fabrication d'un ensemble (10) tête d'impression consistant à sélectionner un sous-ensemble (24) de micromoulage, ledit sous-ensemble (24) comprenant une puce (18) de tête d'impression, une carte imprimée souple (54) et un micromoulage (26). Le sous-ensemble (24) de micromoulage est ensuite fixé à un moulage (28) de recouvrement de manière à former un module (12) d'impression. Ledit procédé consiste, en outre, à former un sous-ensemble (16) réservoir d'encre et à fixer une pluralité de modules (12) tête d'impression au sous-ensemble (16) réservoir d'encre selon un assemblage bout à bout. Enfin, on remplit le sous-ensemble (16) réservoir d'encre et l'on procède au test de l'ensemble complet.
