ABSTRACT:
An integrated orifice array plate and a charge plate are fabricated for a continuous ink jet print head by producing an orifice plate and a charge plate, and by bonding the two together. The orifice plate is produced by providing an electrically non-conductive orifice plate substrate, forming a recessed-surface trench of predetermined depth into one of two opposed sides of the orifice plate substrate, and forming an array of orifices through the orifice plate substrate from the recessed surface of the trench to the other of the two opposed sides wherein the orifices are spaced apart by a predetermined distance. The charge plate is produced by providing an electrically non-conductive orifice plate substrate of predetermined thickness, and forming a plurality of charging leads on one of two opposed sides of the orifice plate substrate. The charge leads are spaced apart by said predetermined distance.
