Three Indium Corporation experts will share their industry knowledge and expertise during four presentations at the 55th International Symposium on Microelectronics (IMAPS) from Oct. 3-6 in Boston, Mass., U.S.

The following technical presentations will be featured:

• A Lead-Free Lower-Temperature Solder Paste for Wafer-Level Package Application by Dr. HongWen Zhang, R&D manager, alloy group

• A Drop-in High-Temperature Lead-Free Solder Paste that Outperforms High-Pb Pastes in Power Discrete Applications by Zhang

• Investigating Optimal Process Parameters for Ultra-Fine Solder Paste Printing in SiP Assembly by Evan Griffith, product specialist

Indium Corporation’s Guangyu Fan, thermal interface materials (TIMs) R&D leader, will present Thermal Performance of Liquid Metal Paste Containing Low Content of Metal Particles for Thermal Interface Materials during a poster session.

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.

Griffith is a product specialist for SEMI/SAAM fluxes and SiPaste® materials. He is responsible for researching and analyzing customer and market data and facilitating current and prospective customers’ needs. Additionally, he supports customers’ enquiries, internal product trainings, and works closely with Indium Corporation’s R&D team on new applications. Griffith earned his Bachelor of Engineering in Materials Science, graduating
