Near-eutectic, high Ag SAC305 solder is the accepted choice for most electronic assembly applications, but some concerns have been raised over the performance of SAC305 in harsh thermal cycling environments, particularly if vibration and shock loading are involved. Additionally, there are problems associated with the high temperature processing required for SAC305, and the cost of high Ag alloys is an issue in some market segments. These recent observations and findings indicate that high Ag alloys are not an optimum or even acceptable solution for other applications. Further, it appears unlikely that a single-alloy solution may not exist across all electronic applications. These sessions share recent process and reliability work done on alloys being considered as alternatives to high Ag SAC305.

Wearables Technology - The Next Manufacturing WaveMurad Kurwa, Flex
A new wave of wearables brings with it plenty of manufacturing and process development concerns. Kurwa will discuss substrate advances like stretchable conductive fabrics, interconnects, new sensor technology including printed sensors (ECG) and OLED, assembly concerns for flexible conductive adhesive and nano-sintering, and encapsulation techniques such as low pressure molding and water proof coating. New equipment like R2R printing and assembly, fabric laser cutting, and ultrasonic welding on fabric will be discussed. The presentation will also address how reliability testing has adapted with flexibility testing, washability, salt spray, and sweat testing.

Extreme Environment Electronics - Where We've Been, Where We Are Going and What Could Be NextJim Springer, John Deere Electronic Solutions
To feed the world population in 2050 it is estimated the current agricultural production must double. Technology is critical to increasing agricultural equipment's utilization and output leading to more efficient farming methods and improved yields. The quality and reliability of electronics used for precision guidance, sensing, controlling engines and other key technologies is essential to optimizing equipment performance. Improving reliability in electronics used in farming is challenging, both in electronic design and manufacturing as well as material selection. This has become more apparent following the global transition of electronic manufacturing from the conventional leaded component technology to lead-free technology. Jim will provide a genesis and the evolution of electronics designed for use in harsh physical and electrical environments, particularly those used in farming and automotive industries. Examples of ruggedization protocols will be discussed.

Electronics Ruggedization Through CoatingChair: Chair: Iulia Muntele, Ph.D., Sanmina Corporation
Co-Chair: Pradeep Lall, Ph.D., Auburn University
Tuesday, September 29 | 11:00am - 12:30pm
Whether it is protection from hostile environments (temperature and/or pressure extreme values, humidity, corrosive atmosphere, UV light, shock and/or vibration), or to aid in the electrical design parameters of a PCBA, conformal coating has been the method of choice for designers. Despite a wide range of coating materials availability, ongoing research efforts continue to close gaps and expand the quest for lighter, easier application and reworkable materials. Both consumer and high-reliability electronics benefit from the results of these research efforts. This session’s presentations bring forth the data acquired in recent investigations of epoxy, silicone, parylene, fluoropolymer coatings, and highlight their applicability in harsh environments with hard to control temperature and moisture levels.

Co-Chair: Matt Kelly, P.Eng., MBA, IBM Corporation
Thursday, October 1 | 8:30am — 10:00am
Consortia activities continue to fill the gaps in Pb-free technology and, in particular, long term reliability. This session begins with the results of a study to examine the effects of surface finishes on the reliability of Pb-free interconnections used with wafer-level, chip-scale packages (WLCSPs). The second presentation investigates the role of conformal coatings on the survivability of quad flat pack, no lead (QFN) packages when the latter are targeted for harsh environments applications. The session is rounded out with an analysis of new Pb-free die attach materials and their performance in thermo-mechanical conditions.
