Indium Corporation Expert to Present During iNEMI Technical Session


Reading time ( words)

Indium Corporation’s Dr. HongWen Zhang, R&D Manager, Alloy Group, will share his industry expertise during the International Electronics Manufacturing Initiative (iNEMI) Packaging Technology Integration Group (TIG) digital meeting on Wednesday, May 27 at 22:00 p.m. JST.

The practice of soldering has been around for thousands of years, but recent advances in soldering materials provide industrial users with more options than ever: low-temperature, middle-temperature, high-reliability solder for automotive applications, and Pb-free high-temperature solder. In Challenges in Solder Materials, Dr. Zhang will discuss why a customer might choose a specific solder product, what potential processing defects exist, and anticipated drop shock performance, reliability, and challenges.

The meeting is open to iNEMI Packaging TIG members. If you wish to participate, please contact iNEMI directly. Dr. Zhang's focus is on the development of lead-free solder materials and the associated technologies for high-temperature and high-reliability applications. He and Dr. Ning-Cheng Lee invented the mixed powder solder technique to combine the merits of constituents to improve wetting, reduce processing temperatures, modify the bonding interface, and control the joint’s morphology, thus improving the reliability. On the basis of this technique, the BiAgX solder system was invented as an alternative high-temperature lead-free solder.

Dr. Zhang has a bachelor’s degree in metallurgical physical chemistry from Central South University of China, a master’s degree in materials science and engineering from the Institute of Metal Research, Chinese Academy of Science, a master’s degree in mechanical engineering, and a Ph.D. in materials science and engineering from Michigan Technological University. 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. Dr. Zhang co-authored two book chapters on high-temperature lead-free bonding materials. He and his colleagues have had seven patents granted globally and have filed numerous other patents. He has published approximately 20 journal publications in the field of metallurgy, materials science and engineering, physics, electronics materials, and mechanics. He has also been invited as a peer reviewer for numerous journals. Dr. Zhang has a Six Sigma Green Belt from the Thayer School of Engineering at Dartmouth College. He is also a certified IPC Specialist for IPC-A-600 and IPC-A-610D.

June Issue of SMT007: A Snapshot of a Resilient Industry

06/30/2020 | Tamara Jovanovic, Happiest Baby
Tamara Jovanovic, an electrical engineer at Happiest Baby in Los Angeles, never imagined that I would have to take half of my lab equipment home to be able to continue doing her job. As she says in her review of the June issue of SMT007 Magazine, the entire industry is adapting to the "new normal," and ready for whatever the future brings.

IPC’s Shawn Dubravac: COVID-19 Outbreak Accelerates Industry Shifts Already Under Way

05/21/2020 | Barry Matties, I-Connect007
On May 19, Barry Matties spoke with Shawn Dubravac, chief economist for IPC. While discussing other topics, Matties asked for Dubravac’s perspective on shifts in the market, who observed that the recessionary trend might be behind us; the markets are already showing recovery. Still, it could take a year or so to fully recover.

Happy’s Smart Factory Protocol Primer

04/29/2020 | Happy Holden, I-Connect007
The smart factory concept is built upon data interchange as the foundation. There has been much development in the area of industrial and manufacturing data protocols over the years, stretching back into the 1960s. This article by Happy Holden surveys what are considered the most common protocols in use in the electronics manufacturing industry today, including IPC-CFX/ Hermes, OML, SECS/GEM, and MAPS.
