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.
Claims10
A print head comprising:
- a die member supporting at least one bond pad and at least one transducer;
- a truncated nozzle plate spaced from the die member, the nozzle plate positioned over the at least one transducer;
- a print head substrate supporting the die member, the print head substrate having an aperture formed therein;
- a sacrificial material positioned over the aperture of the print head substrate and abutting a terminal end of the nozzle plate and an edge of the die member;
- an encapsulant formed between the print head substrate and terminal end of the nozzle plate to seal the sacrificial material therein;
- and
- an enclosed fluid path defined by removal of the sacrificial material from the print head.
