| Abstract | A lid or heat spreader is used for packaging microprocessor chips. There are two primary functions for the lid: dissipate heat efficiently from the microprocessor and provide physical protection to the fragile silicon die. To achieve these two functions, lid material, thermal interface material, lid adhesive and assembly process are key areas of development. Lid adhesive has a critical role in ensuring the whole microprocessor package meets thermal and thermo-mechanical reliability requirements for the microprocessor. Lid adhesive has to provide a good and consistent bonding strength to secure the lid to the organic substrate under various application conditions. At the same time, it also needs to absorb the stresses in the microprocessor package due to thermal mismatch of various materials: silicon, underfill, organic substrate, and lid. Another less known function of lid and adhesive is package warpage reduction. This paper discusses a low-stress lid adhesive material development that features a wide material processing window and fast-cure capability for assembly throughput improvement. |

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.
