| Abstract | The wafer level package (WLP) is a cost-effective solution for electronic package, and it has been increasingly applied during recent years. In this study, a new packaging technology which retains the advantages of WLP, the panel level package (PLP) technology, is proposed to further obtain the capability of signals fan-out for the fine-pitched integrated circuit (IC). In the PLP, the filler material is selected to fill the trench around the chip and provide a smooth surface for the redistribution lines. Therefore, the solder bumps could be located on both the filler and the chip surface, and the pitch of the chip side is fanned-out. In our previous research, it was found that the lifetime of solder joints in PLP can easily pass 3,500 cycles. The outstanding performance is explained by the application of a soft filler and a lamination material. However, it is also learned that the deformation of the lamination material during thermal loading may affect the reliability of the adjacent metal trace. In this study, the material effects of the proposed PLP technology are investigated and discussed through finite element analysis (FEA). A factorial analysis with three levels and three factors (the chip carrier, the lamination, and the filler material) is performed to obtain sensitivity information. Based on the results, the suggested combinations of packaging material in the PLP are provided. The reliability of the metal trace can be effectively improved by means of wisely applying materials in the PLP, and therefore, the PLP technology is expected to have a high potential for various applications in the near future. |

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.
