| Abstract | Wafer level package for optical image sensor devices are known to be processed by re-routing of the bond pads to the back side of the chip, through (T) contacts located at the die edges. Bond pad back via contact wafer level packaging technology has been developed by Schott Electronic Packaging GmbH, Germany, which is proven to be with a number of advantages over the mechanically processed (T) contact wafer level packages. Direct contact of the bond pads from the back side of the chip offers much shorter transmission paths to the board assemblies, thus allowing faster signal speed, efficient thermal conduction and many added advantages. Also, the new technology offers area contacts with in the seal ring/isolation boundary of the device, there-by providing much higher performance for the packaged devices. The reliability of this new WLP technology has been demonstrated by testing the same for various reliability test conditions as per JEDEC/JIS standards. This paper discusses the process technology and reliability tests/results carried out on a consumer application chip, namely image sensor device |

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.
