Lead Free Nanosoldering
Dr. Zhiyong Gu and Dr. Sammy Shina and their chemical engineering research assistant and doctoral candidate, Fan Gao, fabricated tin-based nanowires and analyzed the impact these wires have on performance as an alternative to traditional lead-based soldering techniques currently used in the manufacture of electronics. Their research, entitled "Reflow and Wetting Property of Lead-Free Nanosolders on Reactive Substrates and Printed Circuit Boards", was conducted in collaboration with industry partners, including EMC of Hopkinton, MA, and Benchmark Electronics of Hudson, NH. The goal is to develop innovative manufacturing techniques that do not use lead, minimize product energy consumption, and create a competitive advantage for Massachusetts electronics companies.
