    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: Embodiments herein comprise a compact dust abatement apparatus that includes at least one manifold shaped to fit next to a belt or drum of a printing engine, at least one blower/fan positioned within the manifold, and at least one air duct connected to the manifold. The manifold has a vacuum opening adjacent the belt or drum and an exit opening where the air duct connects to the manifold. The blower is positioned inside the manifold, between the vacuum opening and the exit opening, such that the blower draws air and particles from the vacuum opening toward the exit opening. Thus, the blower creates a vacuum at the vacuum opening. The air duct directs air and particles from the manifold to a location away from the sensitive components. The inclusion of the blower inside the vacuum manifold provides for compactness without sacrificing performance.

    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: An apparatus is used with an ink jet print head in an ink jet printer. The apparatus includes a print head protector that surrounds a print head. A substantially continuous slot is provided along a perimeter of the bracket and a filter is located in the substantially continuous slot. An inlet in fluid communication with the substantially continuous slot enables a positive pressure air supply to be coupled to the inlet. The air entering the inlet flows through the filter in the slot and the filtered air flows outwardly away from the print head.
