Technology Developments to Increase Reliability of Pb-Free Solders
Tim Jensen, Product Manager, PCB Assembly Materials, Indium Corporation
Since 2006 when Pb was restricted in most electronics, there have been many major efforts to ensure reliable Pb-Free solder joints. The technology of electronics devices has also advanced in many ways that further impact reliability. In this presentation, we will cover many of the trends that have the potential to impact solder joint reliability as well as several material and process advancements that have been developed to improve mechanical and thermal reliability of the solder joints.

Minimizing Voiding In SMT Assembly of BTCs
Ron Lasky, Ph.D., Instructional Professor at Dartmouth College and a Senior Technologist at Indium Corporation
Bottom terminated components (BTCs) are one of the most important components in electronics today. Their combination of small size, excellent electrical performance, and ability to transfer heat away from the integrated circuit (IC) has resulted in BTCs becoming one of the most common packages with the highest growth rate. Prismark estimates that in 2016 the most common BTC, the quad-flat pack no-leads (QFN), will comprise 16% of all IC packages at 44 billion with the highest compound annual growth rate of 17%.
Since one of the main strengths of QFNs is dissipating heat, any voiding of the solder connecting the thermal pad on the QFN to that of the printed wiring board (PWB) will degrade the intended performance of the QFN. This degraded thermal performance may result in reliability and operational issues.
As a result of the voiding concern, we and our colleagues have performed a thorough analysis and experimental plan to minimize voiding in QFN assembly. Our experimental plan covers many process and materials parameters. We were successful in reducing voiding to less than 10% in most instances. This presentation will discuss this work.
