Abstract
(EN)
An ink jet printhead has a body of PZT (13') bonded to a base plate (13''). Channels cut in the PZT form ink chambers which are actuated by applying voltages to electrodes on surfaces of the chambers. The base plate also carries IC's which contain the drive circuitry for actuating the ink chambers. To ensure reliable electrical interconnection between the chamber electrodes and the IC's, the electrodes (190', 190'') and conducting tracks (192', 192'') on the base plate are formed in a single step by depositing a conductive layer over both the PZT body and the base plate. The necessary pattern of electrodes and tracks can be achieved by masking or by selective material of conductive material.

L'invention porte sur une tête d'imprimante à jet d'encre comprenant un corps en titanate zirconate de plomb (PZT) (13') fixé à un socle (13). Des canaux découpés dans le PZT forment des compartiments à encre qu'on actionne en appliquant des tensions sur des électrodes placées sur des surfaces desdits compartiments. Le socle porte également des circuits intégrés (CI) comprenant les circuits de commande servant à actionner les compartiments à encre. Pour assurer une interconnexion électrique fiable entre les électrodes des compartiments (190', 190'') et les CI, les électrodes et des tracés métalliques (192', 192'') disposés sur le socle sont formés en une seule passe par dépôt d'une couche conductrice à la fois sur le corps de PZT et sur le socle. Le motif nécessaire des électrodes et des tracés métalliques peut être réalisé par masquage ou par sélection d'un matériau conducteur.
