| Abstract | Trend towards ultra-miniaturization of packages and systems has necessitated the use of high I/O interposers or packages made of either silicon or glass [1]. However, both of these materials have low coefficient of thermal expansion (CTE) compared to organic boards, thereby raising interconnection reliability concerns when assembled directly on the organic system boards. This paper presents an approach to address these reliability problems by using novel build-up dielectrics with low Young's Modulus to reduce the strains induced in the solder ball interconnections to the board. This proposed approach is compatible with surface mount technology and also helps the handling and metallization of thin silicon/glass substrates. Finite element method has been used to analyze the effectiveness of the compliant dielectrics, laminated onto silicon or glass substrates. Parametric study has been performed to analyze the influence of material properties and geometry parameters on the reliability of the SMT interconnections. |

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.
