Optimization of solderability of copper sheet with Sn-Ag-Cu alloy by variations of atmospheric microwave plasma jet (AMPJ) parameters
Abstract
This study used response surface methodology (RSM) to optimize solderability property of copper by variations of atmospheric microwave plasma jet (AMPJ) parameters. Tensile force of adhesion, the main indicator of solderability property, was maximized while minimizing the microwave power, air/Ar flow rate ratio and treatment time. The generated model indicates significant effect (p<0.05) of microwave power, air/Ar flow rate ratio and treatment time to the tensile force. The optimum AMJP parameters of 300 W microwave power, 0.17 air/Ar flow rate ratio and 20.14 seconds treatment time generated a 3.4% error of the predicted tensile force of adhesion compared to the experimental value.
