| Abstract | In addressing emerging high speed interface such as USB 2.0, IEEE1394, LVDS and DVI in electronic devices, discrete solution of using choke and ESD diodes is a common practice in the PCB assembly in eliminating the common mode noise and providing ESD protection to the electronice device [1]. However, this brings up the cost and cycle time as PCB manufacturers have to purchase several components and mount them separately on the PCB. Consequently, a larger PCB footprint is required. In this paper, we introduced the first-to-market integrated common mode filter with ESD protection using package-in-package technology in DFN platform. This is an integrated solution that offers cost savings and space reduction in responds to the needs of portable digital devices which are increasingly smaller and thinner. The attachment of passive component in a DFN package adds complexity to the existing assembly process. The use of lead free solder paste and its selection were discussed in this paper. Solder printing on lead frame was employed for the component placement due to its high process throughput compared to the conventional dispensing method. This paper also elaborated on the stencil design and solder printing characterization. It included the modification in lead frame design to enhance the product quality. The effect of solder reflow was also addressed in the paper. The final product was assembled with the newly established process flow and passed MSL 1 @ 260°C reliability test. The integrated package passed the reliablity stress tests and validated the concept of package-in-package in DFN platform. |

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.
