Abstract
A method and structure for an ink jet printhead, and a printer including the ink jet printhead. The printhead can include a polymer as a film spacer which separates an electrical interconnect such as a printed circuit board or a flexible circuit from a printhead diaphragm, such that the film spacer is interposed between the electrical interconnect and the diaphragm. In an embodiment, a piezoelectric actuator is free from contact with the film spacer. Embodiments of a process for forming the printhead may have reduced processing stages requiring fewer manufacturing tools than some other processes. Embodiments of the resulting printhead and printer may have fewer structural components than some other printheads and printers.
