Publication number: 20220260623Abstract: A system for contactless testing of radio frequency apertures is provided. The system comprises a fixture having a fixture mount operable to be received in a fixture receiver of a robotic system, and a vector network analyzer (“VNA”) supported by the fixture. A radiating antenna is supported by the fixture, and is operable to be connected to the VNA via a cable. Upon movement of the fixture via the robotic system, the VNA, the radiating antenna, and the cable maintain a static positional relationship relative to one another.Type: ApplicationFiled: February 12, 2021Publication date: August 18, 2022Inventors: Christopher J. Fisher, Amanda Couch, John Sherrill, Justin Kasemodel, Justin Stroup, Allen Kelly

Publication number: 20210076505Abstract: An apparatus and method for soldering an electrical component to a circuit board includes a stage positioning the circuit board and electrical component in alignment with a solder tip along an axis. A first spring-loaded compression mechanism maintains contact between the circuit board and the electrical component, and a second spring-loaded compression mechanism brings the soldering tip into thermal contact with the circuit board and the electrical component such that solder disposed adjacent to the circuit board and the electrical component melts. When the second spring-loaded compression mechanism removes its applied force such that the soldering tip comes out of contact with the circuit board, the first spring-loaded compression mechanism maintains the contact between the circuit board and the electrical component while the solder cools and solidifies.Type: ApplicationFiled: September 3, 2020Publication date: March 11, 2021Applicant: Raytheon CompanyInventors: Justin A. Kasemodel, Justin E. Stroup, Allen L. Kelly, Amanda M. Couch, Randy L. Smith

Patent number: 10887978Abstract: Heat transfer devices and systems for thermally coupling electrical components to a heatsink can comprise one or more all-metal heat transfer device(s) thermally coupling at least one electrical component to a heatsink. A heat transfer device can comprise a metal cup attached to a metal heatsink, and a metal piston and a compliant device disposed in the cup. The piston is forcible to a secured first position, upon reflowing solder, while compressing the compliant device. Upon reflowing solder again, the compliant device causes the piston to bias and attach to the electrical component to provide an all-metal thermal path and absorb assembly tolerances to avoid using thermal gap fillers. A method is provided for thermally coupling a heatsink to a plurality of electrical components via a plurality of all-metal, expandable heat transfer devices.Type: GrantFiled: April 30, 2019Date of Patent: January 5, 2021Assignee: Raytheon CompanyInventors: Brian W. Johansen, Justin Kasemodel, James M. Elliott
