The goal of reducing size, weight, and power (SWaP) necessitates designs that increase functionality while, at the same time, further miniaturization. Embedded technology allows the designer to meet these objectives but, it is not without its challenges. This session examines advancements being made in the use of embedded components. The presentations will begin with an analysis of embedded passive devices that have had their use envelope extended to high frequency applications. Follow-on papers consider embedded active devices that include SiC and GaN for high-power assemblies. Device construction, circuit board materials, and interconnection technologies are all critical to the successful execution of embedded technologies in these more demanding applications.

Even with the significant progress made to date, there are still several key areas of R&D and knowledge sharing that remain as portions of the industry continue their transition to lead-free solder assembly. Several market segments continue to learn more about reliability implications and risk mitigation options for tin whiskers, temperature sensitive components, and assembly chemistry electro-migration. This session brings together these topics in three publications from the IPC PERM (Pb-free Electronics Risk Mitigation) Council, HDPug (High Density Packaging User Group), and leading research from an industry materials and solder manufacturer. Together, they encompass today's on-going lead-free R&D and knowledge sharing priorities.

As Pb-free soldering makes further inroads into the high-reliability electronics community, solder joint reliability modeling is taking on many new and exciting pathways. The papers in this session include a re-examination the Norris-Landzberg model that had its beginnings in some of the earliest efforts to predict Sn-Pb fatigue. The second presentation describes the ability to adapt the constitutive model to the microstructural evolution of the solder as a means to improve the fidelity of the predictions. The last two papers summarize an important iNEMI test program that investigated, specifically, the effect of silver (Ag) content on the thermal mechanical fatigue and drop shock resistance of Sn-Ag-Cu solders.
