Fabrication of an inkjet printhead mounting substrate

摘要

A method of fabricating a mounting substrate forming an ink inlet in a first layer of a first dielectric; forming contact pads on a second layer of a second dielectric; forming a slot through the second layer; forming a window through a third layer of a third dielectric; aligning and laminating the second layer to the first layer such that the ink inlet is aligned with the slot; and aligning and laminating the third layer to the second layer so the contact pads and the slot are exposed through the window; providing a printhead die having: a drop mechanism for ejecting drops; a chamber to contain ink; and adhesively bonding the printhead die to the second layer so that the printhead die is disposed within the window and an inlet feed opening of the printhead die is aligned with the slot through the second layer.

1. A method of assembling an inkjet printhead, the method comprising:
forming an ink inlet hole in a first layer made of a first dielectric material; forming a plurality of electrical contact pads on a second layer of a second dielectric material; forming a slot through the second layer; forming a window through a third layer made of a third dielectric material; aligning and laminating the second layer to the first layer such that the ink inlet hole is aligned with the slot; aligning and laminating the third layer to the second layer such that the contact pads and the slot are exposed through the window. providing a printhead die having:
a nozzle array;a drop forming mechanism for ejecting a drop through a nozzle in the nozzle array;a chamber to contain ink near the drop forming mechanism; andan ink feed opening; and adhesively bonding the printhead die to the second layer, such that the printhead die is disposed within the window and the inlet feed opening of the printhead die is aligned with the slot through the second layer.
