Dynamic properties of solders and solder joints

Journal de Physique IV (Proceedings), 2003
The high strain rate mechanical properties have been measured for three types of solder: 63% Sn 37%Pb, 96.5Sn 3.5 Ag and 95.5Sn 3.8Ag 0.7Cu. Bulk properties were measured using a split Hopkinson pressure bar (SHPB) at strain rates from 500 to 3000 s -1 . A novel method has been designed and used to measure the shear strength of solder joints at low and

Influence of Humidity on Voids Formation Inside the Solder Joint

, 2013
Void is defined such as blow hole in the solder joint. Voids may degrade the mechanical and conductive properties of the solder joint and thus decrease the reliability. Article deals with influence of humidity on voids formation inside the solder joint

Temporal Interference Stimulation Enhances Neural Regeneration

Advanced Science, EarlyView.
Temporal interference (TI) stimulation is proposed as a non‐invasive approach to enhance neural regeneration in the deep brain. Theta‐band TI modulation selectively promotes neural progenitor cell differentiation in vitro and augments hippocampal neurogenesis in amouse model of Alzheimer's disease‐like amyloidosis.

Temperature‐Resilient Reconfigurable Physical Unclonable Function Driven by Pulse Modulation Using CMOS‐Integrated Spintronic Chips

Advanced Science, EarlyView.
A reconfigurable physical unclonable function is developed using CMOS‐integrated SOT‐MRAM chips, leveraging a dual‐pulse strategy and offering enhanced environmental robustness. A temperature‐compensation effect arising from the CMOS transistor and SOT‐MTJ is revealed and established as a key prerequisite for thermal resilience.
