Patent number: 9707758Abstract: A micro-fluid ejection head has an ejection chip to expel fluid. It connects to a laminate construct. The construct has vertically configured wiring layers interspersed with non-conductive layers, such as carbon fiber layers. An upper of the wiring layers electrically connects to the ejection chip. The upper layer may also support a planar undersurface of the chip directly on a surface or in a recessed pocket. The two can connect with a die bond, such as one having silica or boron nitride. Fluid connections exist between ink feed slots of the chip and the laminate construct. A silicon tile or other material may also fluidly interconnect with the two. A plastic manifold optionally supports the laminate construct and may fluidly connect to it. The wiring layers of the laminate contemplate ground, power, and various bond pads. Other construct layers contemplate prepreg or core FR4 layers.Type: GrantFiled: September 29, 2015Date of Patent: July 18, 2017Assignee: Funai Electric Co., Ltd.Inventors: Frank Edward Anderson, Richard Earl Corley, Michael John Dixon, Jiandong Fang, Jeanne Marie Saldanha Singh
