Abstract
A single side interconnectable ink jet printhead. In one embodiment thereof, the ink jet printhead includes a lower body portion having a plurality of conductive sections mounted to a top side of the lower body portion and a corresponding plurality of conductive pins projecting from a bottom side of the lower body portion. Each of the conductive sections is electrically connected to the corresponding one of the conductive pins. 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 to 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 c…
