A STUDY OF FACTORS AFFECTING ON SHEAR STRENGTH BETWEEN STAINLESS STEEL AND LEAD-FREE SOLDER

Abstract

This research aims to determine the parameters of appropriate process on soldering between AISI 304 stainless steel and Sn-0.3Ag-0.7Cu lead-free solder. The parameters determined in this study were lap joint, base metal surface and the space of each work piece whereas the responses were shear resistance of joint. In this study, Taguchi method was used as experimental design technique for selecting optimized soldering parameters. The findings reveal that soldering parameters influencing the shear resistance. Moreover, the optimal soldering parameters were determined from the clearance of lap joint 10 mm, base metal surface was 600 grids, and the clearance was 0.3 mm. In addition, the result of prediction reveals that the value of maximum shear resistance was 107.89 N/mm2. Finally, this study had also been verified that the result of prediction error was less than 3.50 %.
