Abstract :
Nanopowders of Sn-3.0Ag-0.5Cu (wt.%) alloy, which has the promising potential applications in microelectronics packaging as the lead free solder, were prepared under the protection of three various coolants. The oxidation of the nanopowders was measured by X-ray diffraction (XRD) and other relative methods to compare the protection of the nanopowders during their preparation. Moreover, the scanning electron microscope (SEM) was employed to measure the morphology and size of these nanopowders. It was observed that the Sn-based nanopowders were almost spherical in shape. In addition, the results showed that nearly the total powders are smaller than 100 nm.
