Abstract
A printhead has an aperture plate on a front side of the printhead, a diaphragm plate on a back side of the printhead, a body intermediate the aperture plate and the diaphragm plate, a chamber disposed within the body, a port boundary defining a port area, the port boundary disposed on the diaphragm plate and adjacent the chamber, a peripheral partially-etched region coinciding with a first portion of the port boundary, and a peripheral non-etched region coinciding with a second portion of the port boundary, wherein the port boundary is fractured at the partially etched peripheral portion and bent at the non-etched peripheral portion, the non-etched peripheral portion structured to prevent separation of the diaphragm plate and a leaflet defined by the partial-etched portion.
