Indium Corporation technology experts will share their technical expertise at the IPC APEX Expo February 19-21 in San Diego, California.

Ning-Cheng Lee, PhD, Vice President of Technology

  • Voiding Mechanism and Control in Mixed Solder Alloy System: Dr. Lee will present data collected while observing the voiding behavior of mixed solder alloy systems under a variety of conditions.
  • QFN Voiding Control via Solder Mask Patterning on Thermal Pad: Dr. Lee will present novel approaches to establishing channels of communications within electronics assemblies.

Ronald Lasky, PhD, PE, Senior Technologist

  • Material and Process Optimization for Head-in-Pillow Minimization: Dr. Lasky will discuss materials- and process-related issues surrounding head-in-pillow defects and make recommendations on how to eliminate the defect.
  • Dr. Lasky will also present posters on Material and Process Optimization for Head-in-Pillow Minimization, Applications of Solder Preforms to Improve Reliability, and A Focus on Productivity: Several Case Studies.
  • Additionally, Dr. Lasky will teach two professional development courses: An Introduction of DOE, SPC, and Weibull Analysis, and Manufacturing for High Yields in Assembly.

Eric Bastow, Senior Technical Support Engineer

  • The Effects of Human-Induced Contamination on PCB Assembly Electrical Reliability: Bastow will discuss how everyday contaminants, such as oil, grease, and hand creams, create reliability issues in small components.
  • Printing I: Bastow will serve as the session chair.
