Patent number: 8703543Abstract: A method to vertically bond a chip to a substrate is provided. The method includes forming a metal bar having a linear aspect on the substrate, forming a solder paste layer over the metal bar to form a solder bar, forming a plurality of metal pads on the substrate, and forming a solder paste layer over the plurality of metal pads to form a plurality of solder pads on the substrate. Each of the plurality of solder pads is offset from a long edge the solder bar by an offset-spacing. The chip to be vertically bonded to the substrate has a vertical-chip thickness fractionally less than the offset-spacing. The chip to be vertically bonded fits between the plurality of solder pads and the solder bar. The solder bar enables alignment of the chip to be vertically bonded.Type: GrantFiled: July 14, 2009Date of Patent: April 22, 2014Assignee: Honeywell International Inc.Inventors: Hong Wan, Ryan W. Rieger, Michael J. Bohlinger

Patent number: 7671478Abstract: A system and method for packaging a magnetic sensor is described. A sensor die is constructed such that connection pads are situated on two opposing sides of the die in two vertical arrays. Bonding wires connect the connection pads on the sensor die to wire bond pads on a substrate. Alternatively, the connection pads are connected to solderable chip pads on the substrate using flip chip bonding. Traces and vias are used to connect the wire bond pads or the solderable chip pads to sensor package pads. The sensor package pads are located on a single side of a sensor package for mounting on a next assembly. The next assembly has a land pattern that includes at least one leveling pad for positioning the sensor die perpendicular to the next assembly while being mounted and a single row of pads for making connections to the sensor package.Type: GrantFiled: September 2, 2005Date of Patent: March 2, 2010Assignee: Honeywell International Inc.Inventors: Lakshman S. Wathanawasam, Michael J. Bohlinger, Tamara K. Bratland, Hong Wan

Publication number: 20090072823Abstract: A 3-axis sensor package with on-board sensor support chip on a single chip. In one aspect of the invention, a sensor package includes an X-axis sensor circuit component, a Y-axis sensor circuit component, or alternatively a combined X/Y-axis sensor circuit component, and a Z-axis sensor circuit component, each mounted to a top surface of a rigid substrate, or alternatively to a printed circuit board (PCB). The pads may be arranged in variety of designs, including a leadless chip carrier (LCC) design and a ball grid array (BGA) design. An application-specific integrated circuit (ASIC), or sensor support chip, is additionally mounted to the top surface of the rigid substrate. The sensor components and ASIC may be ball bonded or wire bonded to the substrate.Type: ApplicationFiled: September 17, 2007Publication date: March 19, 2009Applicant: Honeywell International Inc.Inventors: Hong Wan, Ryan W. Rieger, Michael J. Bohlinger

Patent number: 7271586Abstract: A sensor package comprising an X-axis sensor circuit component, a Y-axis sensor circuit component, and a Z-axis sensor circuit component, each mounted to a top surface of a rigid substrate. To minimize the height of the package, a channel is cut out of the top surface of the substrate in order to accommodate the Z-axis sensor component. On the Z-axis sensor component, input/output (I/O) pads are all arranged in an array along one edge of the sensor to conductively cooperate with I/O pads, or solder-filled vias, on the substrate located at a top edge of the channel. Once the sensors have all been mounted to the substrate, the package is encapsulated, and the overall height is less than 1.2 mm.Type: GrantFiled: December 22, 2004Date of Patent: September 18, 2007Assignee: Honeywell International Inc.Inventors: Michael J.

Patent number: 7202771Abstract: Two sensor units are formed from magnetoresistive material. Elements of the first sensor unit have a total anisotropy field in a first direction. Elements of the second sensor unit have a total anisotropy field in a second direction. An integral coil sets a direction of magnetization in the elements of the first and second sensor units. An output of the first sensor unit is representative of magnetic field components perpendicular to the first direction and an output of the second sensor is representative of magnetic field components perpendicular to the second direction.Type: GrantFiled: March 8, 2006Date of Patent: April 10, 2007Assignee: Honeywell International, Inc.Inventor: Michael J.
