Abstract

Described is a piezoelectric drive element assembly for use in ink jet printer devices. The assembly comprises a piezoelectric drive element, which is characterized by a pair of electrodes spaced apart and thereby electrically isolated from one another on an external lateral face of the drive element. The assembly further includes a printed circuit board having holes through which the drive element is fitted, with the electrodes of the drive element being soldered to opposite sides of the printed circuit board.
