Indium Corporation Research Chemist, Mary Ma, and Area Technical Manager for Eastern China, Wisdom Qu, will present their papers at the 2018 SMTA China South Technology Conference on Aug. 28 in Shenzhen, China. Their papers were voted by their peers as two of the top five "Best Papers" presented in recent years at SMTA South China and SMTA East China, earning them the opportunity to present them again at this year's show.
Ma's paper, Sn3.2Ag0.7Cu5.5Sb Solder Alloy with High Reliability Performance up to 175°C, reviewed the testing results of her efforts to achieve high-reliability under a wide range of high-temperatures using the lead-free solder alloy also known as Indalloy®276. Her paper found that in order to achieve this, it is essential to balance a solder alloy's ability to handle tensile stress versus its rigidity.
Qu's paper, Epoxy Flux – A Low-Cost, High-Reliability Approach to PoP Assembly, describes how epoxy fluxes combine soldering and reinforcement into one single process for increased mechanical, thermal, and electrical reliability with reduced assembly costs.
Ma joined Indium Corporation in 2010 and is based in Suzhou, China. She is responsible for developing halogen-free, lead-free, and no-clean flux chemistries with low-voiding. Ma earned her bachelor's degree in Chemistry from Qufu Normal University and her master's degree in Physical Chemistry from Nanjing University.
Qu is a Senior Technical Support Engineer in eastern China. She provides technical support for Indium Corporation's electronics assembly materials, semiconductor and advanced assembly materials, and epoxy flux products. She is based in Suzhou, PRC. Qu has extensive experience in surface-mount technology and has been with Indium Corporation since 2005. She earned a degree in mathematics from Hubei Radio and Television University in China, and is an SMTA Certified Process Engineer.
