| Abstract | Quadrate Flat Package (QFP) is chosen as package mode of chip for typical Hall-effect current sensors. In this paper, taking the deformation behavior of QFD structure under the temperature loading into consideration, according to related physics laws such as Fourier heat transfer law, Stephen-Boltzmann law and Newton's law of cooling, the thermal simulation of packaging for current sensor is implemented by the finite element method (FEM). The specific implementation method is as follow: taking three power devices (one op-amp, two power tube) as the main research objects in the circuit of the current sensor. In a given model of the thermal boundary conditions (such as power consumption and heat flux), chip structure parameters and material properties, the temperature distribution and deformation of each element are simulated and their influence on the current sensor accuracy are analyzed. |

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.
