【Abstract】 27 prescriptions of experimental solders are fixed through quadratic regressive orthogonal design.Their liquid phase line temperature and wettability are measured separately.Choosing the experimental data of liquid phase line temperature and wettability as parameters,the quadratic regression equations on five alloying elements(Bi,Sb,Ag,Cu,Re) and performance are determined through computer-aided design.According to optimization theory and through establishing mathematics model and utilizing computer program,the optimum solder composed of Sn-Bi-Sb-Ag-Cu-Re is attained.The experimental results show that melting temperature and wettability of the optimum solder are better.更多还原
