摘要： A method and structure for an ink jet print head which includes the use of two or more flexible circuits and a piezoelectric element array. A first pad array is included on a first flex circuit to power a first portion of the piezoelectric element array of the print head, and a second pad array is included on a second flex circuit to power a second portion of the piezoelectric element array of the print head. Using two flex circuits requires only half as many traces to be formed on each flex circuit, which can relax spacing requirements and design tolerances.

摘要： Disclosed is a process for preparing an ink jet printhead which comprises: (a) providing a diaphragm plate having a plurality of piezoelectric transducers bonded thereto; (b) aligning an electrical circuit board having a fill joint with the piezoelectric transducers and temporarily attaching the electrical circuit board to the piezoelectric transducers, thereby creating a layered structure having interstitial spaces between the diaphragm plate, the piezoelectric transducers, and the electrical circuit board; (c) applying a thermoset polymer through the fill joint and allowing it to fill the interstitial spaces via capillary action; and (d) curing the thermoset polymer to form an interstitial polymer layer.

摘要： 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.

摘要： A method of forming a structure such as a print head or a printer including the print head having a flex circuit with a plurality of deformed (i.e., contoured, shaped, or embossed) conductive flexible printed circuit (flex circuit) pads. A plurality of flex circuit pads can be aligned with a plurality of piezoelectric elements of an ink jet print head. Within a press such as a stack press, pressure can be applied to deform the plurality of flex circuit pads and to establish electrical contact between the plurality of flex circuit pads and the plurality of piezoelectric elements. Deforming the plurality of flex circuit pads in situ during the press operation can reduce costs by eliminating a separate embossing stage performed during the manufacture or formation of the flex circuit.
摘要翻译：一种形成诸如打印头或打印机的结构的方法，其包括具有多个变形（即成型，成形或压花）导电柔性印刷电路（柔性电路）焊盘）的柔性电路的打印头。多个柔性电路板可以与喷墨打印头的多个压电元件对准。在诸如叠层压机的压机中，可以施加压力以使多个柔性电路板变形，并且在多个柔性电路板和多个压电元件之间建立电接触。在压制操作过程中原位地形成多个柔性电路板可以通过消除在制造或形成柔性电路期间执行的单独的压花阶段来降低成本。
