| Abstract | As the mobile products have been developed, lots of devices of various functions should be packaged into the limited space. Therefore, as many as possible packaging multi-dies are needed in a small package. Compared with discrete packages, System in Package (SIP) can provide better solutions for power saving, EMI reduction, max frequency upgrade in spite of its higher cost, low test yield, poor quality assurance, and more complicated manufacturing process. But, having many chips in one package has raised concerns related to heat dissipation, which has become one of the most serious problems in the design of SIP. Accordingly, a method to obtain T/sub j/ for each chip from the power inputs is needed. This is quite significant at the SIP promotion and design stage, though the temperature value would be changed by system environment. In this paper, a new approach to determine the junction temperatures of the SIP is proposed. The average temperature of the chips was calculated by RSM, and the temperature difference from the average temperature was calculated by linear superposition. The "hot spot factor", which can reflects the effect of chip size and hot spot on the chip was newly proposed. Using this approach, one can calculate device junction temperatures simply and accurately. |

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.
