| Abstract: | A new Sn-3.0 Ag-0.5Cu based Pb-free solders containing rare Ce,Er,Y and Sc earth elements are studied in this paper and the physical properties,wetting properties and mechanical properties of these alloys are measured,at the same time,the effect of rare earth on the microstructure is also investigated.It is found that rare earth elements would play a different role in the properties of the SnAgCu solder.The solder with the addition of trace rare earth Ce can refine the microstructure and further promote the... |
