Patent number: 8857021Abstract: An ink jet print head can be formed using a laser to melt a plating layer interposed between a piezoelectric actuator and a circuit layer bump. The plating layer can be formed on the circuit layer bump, the piezoelectric actuator, or both, and a laser beam output by the laser is used to melt the plating layer to provide a laser weld. In another embodiment, the circuit layer bump or the trace itself functions as the plating layer, which is melted using a laser to provide the laser weld.Type: GrantFiled: June 15, 2012Date of Patent: October 14, 2014Assignee: Xerox CorporationInventors: Bradley James Gerner, Peter J. Nystrom, Bryan R. Dolan

Patent number: 8814326Abstract: An actuator assembly including a flexible printed circuit and a method for making such an actuator assembly are provided. The flexible printed circuit includes a body having a top side and a bottom side, with the body defining a plurality of bumps extending from the bottom side. A first bump of the plurality of bumps is disposed adjacent to a second bump of the plurality of bumps, and the body further defines at least one relief configured to reduce movement of the second bump caused by movement of the first bump. The flexible printed circuit also includes a plurality of contact pads disposed on the bottom side of the body at least partially at the plurality of bumps, with the plurality of contacts pads being configured to be electrically coupled to a power source and to a piezoelectric transducer.Type: GrantFiled: October 3, 2012Date of Patent: August 26, 2014Assignee: Xerox CorporationInventors: Peter J. Nystrom, Bryan R. Dolan, Bradley James Gerner

Patent number: 8746850Abstract: A printhead for an ink jet printer can be formed as a plurality of substructures which are connected subsequent to inspection and/or testing. A substructure can include a semiconductor substrate such as a silicon substrate having a plurality of heater traces which are used to maintain a temperature of melted solid ink within a tolerance of a desired temperature. The traces can be accurately formed using semiconductor processing techniques. Testing and/or inspecting the substructures prior to assembly can reduce rework and scrap, and can allow the formation of printhead structures from a wide variety of materials.Type: GrantFiled: April 10, 2012Date of Patent: June 10, 2014Assignee: Xerox CorporationInventors: Bradley James Gerner, Peter J. Nystrom

Patent number: 8696091Abstract: Apparatus and methods for heating a printer jet stack. The apparatus includes a first layer and a second layer disposed generally parallel to the first layer. The apparatus also includes a heating layer including a thermal epoxy configured to generate heat when an electrical current is applied thereto. The heating layer is disposed between and bonds together the first layer and the second layer.Type: GrantFiled: May 29, 2012Date of Patent: April 15, 2014Assignee: Xerox CorporationInventors: Bradley James Gerner, Peter J. Nystrom, Andrew W. Hays
