ABSTRACT:
A new thermal ink jet print head designed to have a page wide length. A channel plate is made on a single piece of desired length, preferably the width of the paper being printed, by molding any material that can be molded. Subsequently, the channel plate is hardened to form a rigid structure. Due to the limitations of the silicon chip lengths, as a result of process yield, the heaters are made in plurality of chips and then the heater chips are precisely diced and bonded to the channel plate.
