About

Sooi Jin Lee is a researcher whose work addresses critical challenges in advanced electronics manufacturing, with a particular focus on the reliability and cost-efficiency of lead-free soldering processes. Her key research areas include wave soldering optimization, dross formation reduction, and the mechanical behavior of lead-free alloys. Lee’s most notable contribution is her investigation into the high dross waste generated during lead-free wave soldering—a problem that can waste up to 76% of SAC alloy bar material, making it one of the most costly aspects of modern electronic assembly. Her 2018 paper, "Robotic soldering of lead free alloys," which has garnered 6 citations, explores automated solutions to mitigate these losses and improve process consistency. By addressing the intersection of materials science and manufacturing automation, Lee’s work offers practical insights for reducing industrial waste and lowering production costs. Her research is particularly valuable for engineers and researchers seeking to enhance the sustainability and economic viability of lead-free electronics assembly in an era of increasingly stringent environmental regulations.
