Abstract
A printhead is formed from a plurality of ink ejectors mounted on an inner surface of a rigid substrate while protruding through holes provided in the substrate. Electrical contact is provided on a surface of the ink ejectors common with the ink ejecting nozzles thereby avoiding vias to another surface. The rigid substrate provides a conducting layer on its inner surface such that the ink ejectors may be connected thereto with solder reflow techniques.
