| Abstract | In this study, adopting a dynamic mechanical analyzer (DMA Q800, TA-Instruments), the mechanical properties and fracture behaviors of “copper wire/Sn-3.0Ag-0.5Cu solder/copper wire” sandwich structured microscale solder joints with a constant diameter of 400 μm and a height of 125-325 μm were investigated under two different quasi-static loading modes (i.e., tensile loading and shear loading) at 100 °C. The experimental results show that the tensile and shear strength of all microscale Sn-3.0Ag-0.5Cu solder joints decreased with the increasing of joint height. Under same loading rate of 1N/min at 100°C, the shear strength and shear fracture strain of Sn-3.0Ag-0.5Cu solder joints are much lower than tensile strength and tensile fracture strain, this means the shear stress is more severe for solder joint interconnections in electronic packaging. In addition, the fracture position and fracture mechanism of microscale Sn-3.0Ag-0.5Cu solder joints are significantly different under different loading modes. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
