Abstract:
1. 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.
