Ning-Cheng Lee, Ph.D., Indium.
The conference at IPC Printed Circuits Expo/APEX/Designers Summit, March 30 to April 3 in Las Vegas, covers all aspects of electronics assembly: design, printing, placement, rework, etc. This year, several solder suppliers — including Indium Corporation and Cobar Europe BV — will expound upon a central topic of electronics assembly: solder materials and reflow.
Ning-Cheng Lee, Ph.D., VP of technology, Indium Corporation, will present on high reliability in lead-free solder joints, and the materials considerations that affect soldering. This professional development course is scheduled for March 30. He also will participate in "Future Lead-free Alloys," on April 2, and "A Compliant and Creep-resistant SAC + Al (Ni) Alloy," on April 3.
Indium also is represented by Ronald C. Lasky, Ph.D., senior technologist, and Tim Jensen, solder paste product manager. Lasky will present on rapid RoHS assembly development for large and small PCBs, March 31, and on large PWBs in RoHS 5, 5.5, and 6 environments, April 2. Jensen will speak at the technical conference, covering lead-free reflow coalescence and solder paste transfer efficiency.
Also targeting lead-free assembly, Eli Westerlaken, managing director of Cobar Europe BV, will examine flux performance in his technical paper presentation. "Performing Flux – Technology for Lead-free SN100C Solders," co-authored by Ineke Tiggelen-Aarden, technical director, Cobar Europe BV, is part of the first APEX session on wave soldering, on April 3. The session is moderated by Jasbir Bath, Flextronics International. Westerlaken will speak on the development and implementation of alcohol-based, low-VOC, and VOC-free fluxes for use in lead- and nitrogen-free processing. The paper centers on the SN100C-based wave soldering process.
IPC will host 35 sessions and 100 experts at its technical conference. The presentations were selected for relevancy and impact of the research and findings. Guest speakers will open the technical sessions with an eye on environmental legislation. Huang Jianzhong of the Ministry of Information Industry (MII), China, will address China RoHS, officially titled "Administrative Measure for the Control of Pollution Caused by Electronic Information Products." Patrice Rolett, GM, Avantec, will inform attendees about the EU's Registration, Evaluation, and Authorization of Chemicals (REACH) regulation. For more information, see www.goipcshows.org.
