ABSTRACT:
In a printhead for electrostatic printers, the styli of the printhead are formed on a monolithic substrate, such as a printed circuit board. Each stylus has its own driver circuit incorporated into one or more integrated circuit die which are mounted directly on the monolithic substrate, and electrically connected to traces formed on the printed circuit board. The styli are the ends of the traces as formed on the edge of the substrate. The integrated circuit die are connected to the traces by wire bonding or TAB bonding. The printhead is implemented in monoscan, biscan, triscan, and various other configurations.
