Article Synopsis
  • Researchers studied a solder alloy (Sn99Ag0.3Cu0.7) reinforced with different sizes of ZnO nanoparticles to understand how they affect the alloy's properties.
  • They found that adding ZnO reduced the wettability, which led to more voids in the solder, but the mechanical strength and thermoelectric performance remained similar to the standard alloy.
  • Improved wettability could be achieved with more active fluxes, suggesting that these ZnO composite solders might be beneficial for high-power applications.
