Grain features of SnAgCu solder and their effect on mechanical behaviour of micro-joints [PDF]
, 2006 SnAgCu alloy, which promises compatible properties with Sn-Pb solder, has been identified as one of the most potential Lead-free solders for electronic interconnections. However, due to the miniaturization of solder joints, a micro-joint of this material

Electrohydraulic Folding Ring Actuators for Radially Contracting Applications
Advanced Science, EarlyView.This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...

Cross-interaction of interfacial reactions in Ni (Au/Ni/Cu)-SnAg-Cu solder joints during reflow soldering and thermal aging [PDF]
, 2007 The coupling effect of interfacial reactions between two pads in Ni-SnAg-Cu and Au/Ni/Cu-SnAg-Cu solder joints was investigated in this paper. After reflow soldering, a large amount of Cu can diffuse across the solder joint to the opposite pad to form ...
