In this paper, four kinds of solder-SAC305, SAC0307, SAC0307-0.07La and SAC0307-0.07La-0.05Ce were prepared by experiment. The BGA solder joints (whose diameter is 900µm) of board-level structure was obtained by twice reflow soldering. We analyzed the shear strength, the fracture mode, and the fracture mechanism by applying shear load. At the same time, the effect of the thickness and morphology of...
The reliability of SAC lead-free solder joints are believed to be greatly influenced by the interfacial intermetallic compounds (IMCs) between solders and substrates. Our previous works investigated the effects of minimal rare earth (RE) elements addition on the interfacial IMCs under different aging time. Experimental results showed that the appropriate RE content is 0.07wt% La in Sn-0.3Ag-0.7Cu...
It is gradually recognized that Sn-Ag-Cu is better alloy system for application prospect in the lead-free solders. In order to cut down the cost and improve properties, researchers have always been searching for proper compositions and adding elements to improve properties actively. This paper has investigated the effect of Ni addition on Sn-0.3Ag-0.7Cu (SAC0307) low-Ag solder joint. The results of...
