In this investigation, Scanning Electron Microscopy (SEM) and Scanning Probe Microscopy (SPM) have been utilized to examine aging induced microstructural changes occurring …
Reliable lead free solders are needed for products exposed to extreme environments such as those used in the automotive, avionics, and oil-exploration industries, as well as in …
One of the most common method of failure in electronic packaging is the fatigue failure of solder joints. The constituent materials forming the electronic assembly have different …
In this investigation, the effects of isothermal mechanical cycling on damage accumulation in lead free SAC305 and SAC_Q (SAC+ Bi) solder joints have been explored. In particular, we …
Lead free solder materials are susceptible to significant creep deformations in harsh high temperature environments including automotive, avionics, military, and oil exploration …
In this work, we have examined the ability of microalloy additions (dopants) to reduce aging effects in solder joints by nanoindentation testing of several sets of doped/non-doped alloys …
