Indium Corporation Expert to Present on Unique High-Reliability Alloy Technologies at IEMT
September 23, 2022
Indium Corporation will share its industry knowledge and expertise on topics including high-temperature lead-free solder pastes for power discrete applications, and low-temperature solder pastes for wafer-level packaging applications, during two presentations at the International Electronics Manufacturing Technology (IEMT) conference, Oct. 19-21, Putrajaya, Malaysia.
Indium Corporation's Durafuse™ HT, Sn-based high-temperature lead-free (HTLF) solder pastes designed with Durafuse ™ technology and the combined merits of two constituent alloys, have been developed as drop-in solutions to replace the high-Pb solder pastes in power discrete applications. In his presentation, A Drop-in High-Temperature Lead-Free Solder Paste that Outperforms High-Pb Pastes in Power Discrete Applications, Dr. HongWen Zhang, R&D manager, alloy group, will examine the results of a study that compared Durafuse™ HT's performance to high-lead products.
In his presentation on low-temperature solder paste, Novel Lead-Free Lower-Temperature Solder Paste for Wafer-Level Package Application, Zhang examines the results of testing an indium-containing, low-temperature solder paste—Indium Corporation's Durafuse™ LT—for wafer-level package (WLP) applications. During the test, Durafuse™ LT, regardless of reflow profiles, outperformed SAC305.
Dr. Zhang is manager of the alloy group in Indium Corporation's R&D department. His focus is on the development of Pb-free solder materials and the associated technologies for high-temperature and high-reliability applications. He was instrumental in inventing the mixed-alloy solder technique to combine the merits of constituents to improve wetting, reduce processing temperatures, modify the bonding surface, and control the joint's morphology, thus improving reliability. Dr. Zhang has a bachelor's degree in metallurgical physical chemistry from Central South University of China, a master's degree in materials and engineering from the Institute of Metal Research, Chinese Academy of Science, and a master's degree in mechanical engineering and a Ph.D. in material science and engineering from the Michigan Technological University. He has a Six Sigma Green Belt from the Thayer School of Engineering at Dartmouth College, and is a certified IPC Specialist for IPC-A-600 and IPC-A-610 as well as a certified SMT Process Engineer. He has extensive experience in various aluminum (Al) alloys and fiber/particle reinforced Al-based composite materials, and Al-rich and ZrHf-based amorphous alloys. He has co-authored two book chapters on high-temperature lead-free bonding materials, has had a number of patents filed, and has been published in approximately 20 journals in the fields of metallurgy, materials science and engineering, physics, electronics materials, and mechanics.
