Patent number: 10887979Abstract: A system for reducing low cycle fatigue of a soldered connection includes a controller and a heating element operatively connected to the controller. The system also includes a printed wire board soldered in connection with an electronic component. The controller is configured to retrieve a signal indicative of a temperature of the electronic component, and compare the temperature to a stored predetermined range of operating temperatures. Responsive to determining that the temperature of the electronic component is less than a lower threshold temperature of the predetermined range of operating temperatures, the controller transmits a signal to the heating element that causes the heating element to heat the electronic component. The controller then saves, to an operatively connected computer readable memory, a magnitude of temperature difference and a number of times that magnitude is reached. The controller uses the stored information to track the life of the electronic component.Type: GrantFiled: January 10, 2018Date of Patent: January 5, 2021Assignee: HAMILTON SUNSTRAND CORPORATIONInventors: Mark Hamilton Severson, Ryan W. Schmid
