Enhancing PCB Reliability: Voiding Reduction Design with a Mixed-Alloy Solder, presented by Technical Support Engineer Thuy Nguyen, and co-authored by Dr. Hongwen Zhang, Dr. Ronald C. Lasky, and Adam Murling.
- This presentation explores the development of novel mixed-alloy solder paste Durafuse® HR, which reduces voiding while maintaining high-reliability thermal cycling performance, offering improved solutions for automotive, high-performance computing, and 5G communication applications.

Novel Supercooled Solder Materials for Lower-Than-Liquidus Reflow presented by R&D Manager Dr. Ian Tevis, co-authored by Dr. Yifan Wu and Radhika Jadhav.
- This presentation showcases the development of supercooled solder pastes using core-shell bismuth-tin (BiSn) particles, enabling reliable solder interconnects at temperatures 40°C lower than conventional reflow profiles, making them ideal for future electronics manufacturing and temperature-sensitive applications.

Liquid Metal Paste High-Speed Dispensing for High-Volume Manufacturing – Part II, co-presented by Senior Product Specialist Miloš Lazić and Sunny Agarwal, ITW EAE. Co-authored by Dr. Ricky McDonough.
- This presentation examines the advancements in liquid metal paste (LMP) technology, showcasing its enhanced thermal conductivity and adaptability for high-performance computing applications, while addressing challenges associated with traditional liquid metal thermal interface materials (TIMs).

Phase-Change Metal (PCM) TIMs for Enhanced Thermal Management – Part II, presented by Miloš Lazić, co-authored by Dr. Ricky McDonough and Bob Jarrett.
- This presentation introduces newly developed gallium-based and gallium-free phase-change metal (PCM) TIMs, designed to remain in a liquid state at operating temperature, delivering exceptionally low thermal resistance. Power cycling and HAST data highlight their robust performance and underscore the necessity of containment strategies, while gallium-free solutions enable compatibility with aluminum heat-sinks.
