Transient dynamic loads in addition to prolonged periods of high temperature exposure are a part of number of high profile applications with high reliability needs. Examples include - electronics in automotive applications may be mounted under the hood or in the trunk of the car resulting in prolonged periods of high temperature exposure followed by operation under vibration while at environmental...
The effect of aging on mechanical properties of SAC 305 at low strain rate has been investigated. For high strain rate constitutive mechanical behavior, a number of researchers relied on Split Hopkinson Pressure bar and the strain rate range is from 500/s to 3000/s. However, for typical drop and shock, the strain rate range is from 1/s to 100/s. There is a general scarcity of data for solder materials...
Industry migration to leadfree solders has resulted in a proliferation of a wide variety of solder alloy compositions. The most popular amongst these are the Sn–Ag–Cu family of alloys like SAC105 and SAC305. Electronics subjected to shock and vibration may experience strain rates of 1–100/s. Electronic product may often be exposed to high temperature during storage, operation and handling in addition...
Electronics in downhole drilling, automotive and aerospace applications is expected to sustain prolonged periods of operation at high temperature while being subjected to shock and vibration. High temperature shock and vibration loads may be generally in the strain rate range of 1-100 per sec. Material data on properties at elevated temperatures and high strain rates is scarce. There is lack of material...

Leadfree solders have been used as interconnects in electronic packaging, due to its environmental friendly chemical property. However, those materials may experience high strain rates when subjected to shock and vibration. Consequently, failure will occur to electronics in those situations. Therefore, knowing the material properties of lead-free solders are extremely important, but research on mechanical...
