Investigation of Microstructural Evolution in SAC Solders

Abstract:The microstructure and mechanical properties of Sn-Ag-Cu (SAC) solder joints in electronic assemblies are constantly evolving when exposed to isothermal aging. In particular, both the stress-strain behavior and creep behavior of SAC solders degrade significantly with aging exposures. These changes in solder mechanical behavior are a result of the evolution of the solder Irradiation Creep - an overview ScienceDirect TopicsIrradiation creep and void swelling are interrelated processes. Thus, irradiation creep can be categorized into four stages:the transient regime, the creep regime in the absence of swelling, swelling-enhanced creep, and creep disappearance [173].The irradiation creep transient is mainly involved with the transient evolution of the dislocation density to achieve quasiequilibrium and is
