Indium Corporation experts will present technical findings at IPC Midwest Conference & Exhibition, September 21-22, 2011, in Schaumburg, Illinois.

Indium Corporation's Vice President of Technology, Dr. Ning-Cheng Lee, will present Thermal Pad Design at QFN Assembly for Voiding Control, which analyzes and presents the effects of variables on voiding.

Indium Corporation's Senior Technologist, Dr. Ronald C. Lasky, Ph.D., will be presenting Low Silver Solder Alloys with Good Drop Shock and Thermal Cycle Reliability. Low silver lead-free alloys have been shown to have superior drop shock performance, but people have questioned whether or not their thermal cycle performance is adequate. This paper will discuss these issues.

Dr. Lasky will also be presenting the tutorial Lead-Free Assembly for High Yields and Reliability, which will provide a framework for discussion of quality, manufacturability and reliability, and for examination of material properties and design parameters. It will also explore options for increasing the reliability of electronics assemblies.

In addition, Dr. Lasky will moderate Minimizing Defects in Assembly Processing.

Dr. Lee is a world-renown soldering expert and an SMTA Member of Distinction. He has extensive experience in the development of high-temperature polymers, encapsulants for microelectronics, underfills, and adhesives. His current research interests cover advanced materials for interconnects and packaging for electronics and optoelectronics applications, with emphasis on both high performance and low cost of ownership.

Dr. Lasky has more than 30 years experience in electronic and optoelectronic packaging and assembly, including work at IBM, Universal Instruments and Cookson Electronics. He has authored or edited five books on science, electronics, and optoelectronics, as well as several technical papers and articles for Scientific American. Dr. Lasky holds numerous patent disclosures and is the developer of several new concepts in SMT processing software relating to cost estimating, line balancing and process optimization. He is the co-creator of engineering certification exams in electronics assembly and is the director of Dartmouth's Six Sigma Program. Dr. Lasky was awarded the SMTA Founder's Award in 2003. He also authors a technology blog which can be found at
