| Abstract | The interfacial adhesion between two packaging materials is important to package reliability performance. This paper compares the interfacial characterization technique of hot and standard die shear tests versus the double cantilever beam (DCB) method. The study involved the interfacial adhesion of die attach material to the soldermask, the core surface of an organic substrate, and the silicon die surface. Both room temperature and heated shear tests showed a cohesive failure mode and thus presented difficulties in quantifying the interface adhesion between materials interfaces. The DCB tests resulted in a reproducible adhesive failure under mode 1 condition for the tested interfaces. The computed energy release rate $G_{c}$ quantified the adhesion between the different interfaces. The package reliability of the different interfaces was assessed in FBGA packages with their failure modes correlated to the adhesion strength and failure modes of the DCB test. The DCB test is recommended as a material selection tool, to be used in conjunction with shear tests for materials or surface selection. |

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.
