    摘要: A method of forming an enclosed fluid path in a print head includes providing a die member and a truncated nozzle plate spaced from the upper surface of the die member. The die and nozzle plate are formed on a print head substrate having an aperture formed therein. A sacrificial material is seated over the aperture of the print head substrate and joins a terminal end of the truncated nozzle plate. The sacrificial material is encapsulated from the terminal end of the nozzle plate to a surface of the print head substrate. Removal of the sacrificial material defines the fluid path from the aperture of the print head substrate to the nozzle plate.

    摘要: A heat sink, provides a heat transfer pathway to remove heat from the rear face of a printhead substrate. The heat sink is located between the printhead substrate and the printer carriage. The heat sink may, in one embodiment, be biased to float substantially normal to the rear face of a printhead substrate using a biasing device, such as one or more springs, or a one or more spring clips. The springs, which are compressed, tend to urge the face of the heat sink against the back face of the printhead, forming an interface between the two faces. Additional force can be provided by a carriage arm, as its radius acts as a moment arm to assist in pressing the two faces together. A low thermal heat conductivity contact resistance and an improved thermal resistance to heat dissipation between the printhead substrate and the heat sink are provided by the high pressure interface resulting from the use of the springs and the radius of the carriage arm. An additional layer of heat conductive material can be provided at the interface of the heat sink and the printhead substrate. This can reduce the ability of air pockets to form between the heat sink and the printhead substrate. The additional layer is a fabric or thermal grease material which is effective to fill rough areas of surface on either the printhead substrate or the heat sink contact areas.

    摘要: An integral seal for priming or maintaining the nozzles or orifices of an ink jet printhead in an ink jet printer. The ink jet printhead includes a plurality of ink ejecting orifices arranged on a surface of the printhead and includes a seal integral with the surface which surrounds the ink ejecting orifices. The seal member is located within a recess formed in the surface and has a contacting surface which can be recessed from the ink ejecting orifices so that cleaning operations of the surface which, for instance, use a wiping blade, are not impeded. A capping member on a maintenance station contacts and slightly compresses the seal member to provide an airtight seal during priming/maintenance operations.

    摘要: An ink jet print head including a plurality of standoff layer supports in an interstitial region between adjacent piezoelectric elements, and method of formation. The plurality of standoff layer supports can be formed from the same layer(s) as the piezoelectric elements, or from a dielectric layer such as a polymer. The standoff layer supports increase an area to which a standoff layer can be attached, thereby forming a more secure attachment of a circuit layer such as a flex circuit or a printed circuit board to a jet stack subassembly.

    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 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, electrically coupling a plurality of conductive elements to the plurality of piezoelectric elements, and curing the interstitial layer. A plurality of electrically isolated conductive particles within the interstitial layer electrically couple the plurality of conductive elements to the plurality of piezoelectric elements. The conductive particles can be evenly distributed throughout the totality of the interstitial layer dielectric, or they can be localized over a top surface of each piezoelectric element and interposed between the plurality of piezoelectric elements and the plurality of conductive elements. The conductive elements can be part of a flex circuit or printed circuit board.

    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.
