Five of Indium Corporation's technology experts will present their technical findings at APEX in Las Vegas, Nevada, April 6-9, 2010.

  • Ning-Cheng Lee, Ph.D, Vice President of Technology
  • Ronald C. Lasky, Ph.D. PE, Senior Technologist
  • Mario Scalzo, Senior Technical Support Engineer
  • Eric Bastow, Senior Technical Support Engineer
  • Chris Anglin, Applications Development Engineer

Dr. Lee is presenting three papers; Lead-Free Flux Technology and Influence on Cleaning. Lead-free, cost pressures, and the never-ending question of "how clean is clean?" present assembly operations with constant challenges. This paper addresses those challenges.

Tuesday, April 6 – 1:30 - 3:00pm

Selection of Dip Transfer Fluxes and Solder Pastes for PoP Assembly. This paper discusses the market outlook, assembly process methodologies and key infrastructure elements that have evolved to enable integrating the new generations of high-performance discreet logic and memory die elements within a single package outline.

Wednesday, April 7 – 10:15 – 11:45am

Achieving High Reliability Low-Cost Lead-Free SAC Solder Joints Via Mn or Ce Doping. In this study, low Ag SAC alloys doped with Mn or Ce were evaluated against eutectic SnPb, SAC105, and SAC305 for JEDEC drop, dynamic bending test, temperature cycling, and cyclic bending tests.

Wednesday, April 7 – 1:30 – 3:30pm
