Abstract
A method of forming an enclosed fluid path in a print head includes providing a die member and a truncated nozzle plate spaced from the upper surface of the die member. The die and nozzle plate are formed on a print head substrate having an aperture formed therein. A sacrificial material is seated over the aperture of the print head substrate and joins a terminal end of the truncated nozzle plate. The sacrificial material is encapsulated from the terminal end of the nozzle plate to a surface of the print head substrate. Removal of the sacrificial material defines the fluid path from the aperture of the print head substrate to the nozzle plate.

A method of forming an enclosed fluid path in a print head comprising:
- providing a die member;
- forming a truncated nozzle plate spaced from an upper surface of the die member;
- providing a print head substrate and an aperture formed in the print head substrate;
- positioning the die member on a surface of the print head substrate with an edge of the die member and a terminal end of the truncated nozzle plate being adjacent to the aperture of the print head substrate;
- placing a sacrificial material over the aperture of the print head substrate and joining the terminal end of the truncated nozzle plate;
- encapsulating the sacrificial material from the terminal end of the nozzle plate to the surface of the print head substrate;
- and
- removing the sacrificial material to define the fluid path from the aperture of the print head substrate to the nozzle plate.
