Claims19
An orifice plate comprising:
- a central area having an orifice;
- and
- an edge area surrounding the central area and proximate to edges of the orifice plate, the edge area having an aperture therein.
A fluid ejection device comprising:
- a substrate;
- and
- an orifice plate having opposing corner areas with an aperture therein, wherein the orifice plate adheres to the substrate.
A fluid ejection device comprising:
- an active layer formed over a substrate, wherein the active layer has a heating element;
- a barrier layer formed over the active layer, wherein the barrier layer has a chamber associated with the heating element;
- an orifice plate formed over the barrier layer, the orifice plate having a central area with an orifice, and an edge area surrounding the central area and proximate to edges of the orifice plate, the edge area having an aperture, wherein the orifice is positioned over the chamber and heating element;
- and
- glue adhering the orifice plate and the barrier layer,
- wherein the glue is exposed in the aperture of the orifice plate.
3 more elements
A method of manufacturing an orifice plate, comprising the steps of:
- forming an orifice in a central area of the orifice plate;
- and
- forming an aperture in an edge area surrounding the central area and proximate to edges of the orifice plate.
A method of adhering an orifice plate of a fluid ejection device to a barrier layer of the fluid ejection device, the method comprising:
- applying glue to the barrier layer;
