Indium Corporation's Dr. Ning-Cheng Lee, vice president of technology, and Sehar Samiappan, area technical manager for North Malaysia, the Philippines, and Vietnam, will present at the 35th International Electronics Manufacturing Technology Conference November 6–8 at the Kinta River Front Hotel, Ipoh, Perak, Malaysia.

Sehar's paper, The High-Melting, Lead-Free, Mixed BiAgX Solder Paste System, explains the research involved in identifying lead-free alternatives for high-melting, high lead-containing solder alloys. The presentation also discusses a novel high-melting, lead-free, BiAgX® mixed solder paste system, and compares its performance to several representative high lead-containing solder alloys. Sehar will present on November 8. The paper is available for download from Indium Corporation's technical library located at

In addition, Dr. Lee, a world-renown expert in soldering technology, will be teaching a professional development course on Achieving High Reliability Lead-Free Solder Joints on November 6.
