| Abstract: | The text analyzes the reason why it is hard for normal cyclone-separator to classify Sn-Pb alloy solder powder and presents the methods of improvement. Furthermore, a new cyclone-separator was prepared to classify Sn-Pb alloy solder powder. Then, the diameter of classification was 15um and oxidation rate were decreased 30 ppm . The products classified by the new equipment are much better in quality. In addition, the cost of the equipment can be decreased much and the benefits of society and economy are obvious compared to the turbine superfinec lassifier. |
