| Abstract | By integrating the MPM (multi package module) and flip chip (FC) technologies together, the MPM-FCBGA package can increase performance and allow miniaturization. This also offers a lower-cost solution for customers who desire SoC (system on-a-chip)-like qualities in their IC packages. However, the more functionality integrated in MPM-FCBGA leads to the extreme increase in package power density, which becomes a main challenge for package designers. A successful MPM-FCBGA development to fulfill customer demands is highly related to a state-of-the-art thermal characteristic analysis. This paper investigates several thermal such like as heat spreader (HS) types, heat spreader materials (copper and aluminum alloy), substrate materials (BT and ceramic) and PCB design with cavity to allow thermal gel filled connecting of the FC and ground plane. All analyses were conducted by numerical analyses utilizing a commercial finite differential analysis (FDA) program, Flotherm. Finally, the advanced PCB design with cavity achieved greatest benefit with 12% reduction in FC junction temperature. |

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.
