摘要： A method for assembling a printhead such as an ink jet printhead can include the use of an ultrasonic bonding process to bond two or more printhead layers together. In an embodiment, an ultrasonic frequency is directed to an interface between a first layer and a second layer to generate heat at the interface. In an embodiment, the heat melts at least one of the first layer and the second layer, and the layers are cooled to cure the melted layer. In another embodiment, the heat generated using the ultrasonic frequency cures an adhesive layer between the first layer and the second layer. The ultrasonic lamination process described can result in a fluid-tight seal which requires less processing time and materials over an adhesive-based process.

摘要： A method for assembling a printhead such as an ink jet printhead can include the use of a laser to bond two or more printhead layers together. In an embodiment, a laser beam is directed through a transparent layer to an energy-absorbing layer, where the energy-absorbing layer is melted such that after removal of the laser beam the melted layer solidifies to adhere the energy-absorbing layer to the transparent layer. In another embodiment, heating the energy-absorbing layer melts the transparent layer to adhere the energy-absorbing layer to the transparent layer after removal of the laser beam. The laser transmission lamination process described can result in a fluid-tight seal which requires less processing time and materials over an adhesive-based process.

摘要： A print head including a jet stack can be formed using semiconductor device manufacturing techniques. A blanket metal layer, a blanket piezoelectric element layer, and a blanket conductive layer can be formed over a semiconductor substrate such as a semiconductor wafer or wafer section. The piezoelectric element layer and the blanket conductive layer can be patterned to provide a plurality of transducer piezoelectric elements and top electrodes respectively, while the metal layer forms a bottom electrode for the plurality of transducers. Subsequently, the semiconductor substrate can be patterned to form a body plate for the print head jet stack. Forming a print head jet stack using semiconductor device manufacturing techniques can provide a high resolution device with small feature sizes.

摘要： A method for forming an ink jet print head can include attaching a plurality of piezoelectric elements to a diaphragm, dispensing an interstitial layer over the diaphragm, and forming a plurality of patterned conductive traces on the interstitial layer to physically and electrically contact the plurality of piezoelectric elements. The plurality of patterned traces can be formed using, for example, photolithography, a lift-off process, laser ablation, etc. Electrical communication between the plurality of patterned conductive traces and the plurality of piezoelectric elements can be established through surface contact between the two structures, without the requirement of a separate conductor.

摘要： A method for forming an ink jet print head can include attaching a plurality of piezoelectric elements to a diaphragm of a jet stack subassembly, electrically attaching a flex circuit to the plurality of piezoelectric elements, then dispensing an dielectric underfill between the flex circuit and the jet stack subassembly. The use of an underfill after attachment of the flex circuit eliminates the need for the patterned removal of an interstitial material from the tops of the piezoelectric elements, and removes the requirement for a patterned standoff layer. In an embodiment, electrical contact between the flex circuit and the piezoelectric elements is established through physical contact between bump electrodes of the flex circuit and the piezoelectric elements, without the use of a separate conductor, thereby eliminating the possibility of electrical shorts caused by misapplication of a conductor.

摘要： A method and structure for forming an ink jet print head having a dielectric interstitial layer. A flexible top plate attached to a press can be used to apply pressure to an uncured dielectric interstitial layer. The uncured dielectric interstitial layer is cured while contacting the uncured dielectric interstitial layer with the flexible top plate and applying pressure using the press. Using a flexible top plate rather than a rigid top plate has been found to form a cured interstitial layer over an array of piezoelectric elements which has a more uniform or planar upper surface. An interstitial layer so formed can result in decreased processing time, reduced problems with ink communication in the ink jet print head during use, and decreased manufacturing costs.

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.
