Title: SINGLE SIDE DRIVE SYSTEM INTERCONNECTABLE INK JET PRINTHEAD AND METHOD OF MANUFACTURING THE SAME
Abstract:
A single side interconnectable ink jet printhead and an associated method for manufacturing the same. The ink jet printhead includes a lower body portion (14) having a plurality of conductive sections (16) mounted to a top side (14a) of the lower body portion (14) and a corresponding plurality of conductive pins (20) projecting from a bottom side (14b) of the lower body portion (14). Each of the conductive sections (16) is electrically connected to the corresponding one of the conductive pins (10). A bottom side surface of each one of a plurality of generally parallel, longitudinally extending first intermediate body portions each formed of an active piezoelectric material poled in a first direction parallel to the top side surface of the lower body portion is conductively mounted to a portion of the top side surface of the lower body portion. A bottom side surface of each one of a plurality of generally parallel, longitudinally extending second intermediate body portions, each formed of an active piezoelectric material poled in a second direction opposite the first direction is conductively mounted to a top side surface of a corresponding one of the first intermediate body portions and a bottom side surface of an insulative upper body portion is conductively mounted to a top side surface of each of the plurality of second intermediate body portions.
