Abstract

Recently, sintering joint using Ag-nanohas been attracting attention as a new joint method to replace the solder. However, the joint layer would contain a lot of voids after sintering processes. Since the voids affect mechanical property, the proper sintering conditions have to be selected in order to reduce these voids. In this research, the authors focus on the effect of pressure conditions at sintering process. Then, by creating FEM models including voids from cross section image of the joint layer and carrying out tensile analysis, the mechanical property of the joint layer has been acquired. Using this approach, the influence of pressure conditions on the mechanical properties is revealed.
