| Abstract | Embedding of semiconductor chips into organic substrates allows a very high degree of miniaturization by stacking multiple layers of embedded components, superior electrical performance by short and geometrically well controlled interconnects as well as a homogeneous mechanical environment of the chips, resulting in good reliability. At PCB manufacturing level, 50 mum thin chips have been embedded with pitches up to 200 mum in up to 18ldquotimes24rdquo panels. Embedding of chips at 100 mum pitch has been achieved at prototype level. Further developments of chip embedding can extend to even finer pitches without redistribution methods only with concurrent developments in ultra fine line patterning, plating methods and chemistries, assembly machines. New manufacturing processes should combine PCB processing and die assembly in one production line in order to benefit the most from this combination without the difficulties of transport between different manufacturing plants. Furthermore, new testing methodologies will be developed and a new supply chain will be created due to incorporation of embedding technologies to PCB production. This paper discusses in detail the technology and manufacturing challenges arisen from the integration of embedding technologies to PCB manufacturing processes. |

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.
