A Novel Non-Contact Soldering Iron/Heat Gun for Electronics Fabrication

While contact-based soldering irons have been sufficient for the Navy’s needs for a number of years, the need to support new lead-free and older leaded solders is impossible with the current soldering irons without the risk of cross-contamination. In addition, the combination of the soldering iron and heat gun into one device would reduce costs and operational constraints. Creare’s innovation is a novel Non-Contact Soldering Iron (NCSI) that can solder electrical connections and also function as a heat gun. The total weight of our battery-powered NCSI is approximately 2.5 lb and is similar to that of a common household flashlight. We have used low cost components such that the final cost of our NCSI will be approximately $95. Thus, our solution is flexible, lightweight, affordable, and portable. Our NCSI combines the benefits of non-contact, radiation-based soldering with the convenience of a hand-held, battery-powered device. In Phase I, we will establish the foundation for further development and technology transfer at the completion of Phase II. Creare will work closely with the U.S. Navy and the program offices during Phases I and II to ensure that we are responsive to the needs of DoD maintenance and flight-line efforts.
