| Abstract | Lead-free solders were prepared by adding small amount of Bi element into the near eutectic Sn-Ag-Cu alloy solder. Melting point tests were carried out by DTA (Differential Thermal Analysis). Wettability tests were conducted on a wetting balance instrument. Test results of the experimental solders were compared with that of Sn-3.5Ag-0.5Cu to explore the effects of the addition of Bi on the microstructure, melting point, conductivity and wettability of the lead-free solders. It shows that Bi addition has positive effects on depressing the melting temperature but broadening the melting range. And with proper addition, Bi has a slight positive effect on wettability and conductivity. With the proper addition of Bi, grain refining effect can be achieved for the eutectic phases and thus it may improve the microstructure stability of the solders. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
