Abstract Scope |
Ag–10 wt% Sn alloy powders for die attachment of high-temperature power devices packaging are prepared by high energy ball milling of high-purity Ag and Sn powders in argon atmosphere. Stearic acid was added as process control agent in order to prevent agglomeration of the powders. Planetary ball-mill was performed in different speed for 1, 2 and 6 hr to determine the effect of milling speed and time. Characterization of the powders was carried out by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM) to gain insight on the phase transformations and confirm the completion of alloying process. The morphology of the Ag–Sn powders was flake-like, with particle size within the micro size range. |
