| Abstract | Harris Corporation has undertaken a multi-chip module (MCM) project that will develop a four-channel digital RF receiver for use in very dense, lightweight systems. This MCM is designated the Digital Drop Receiver (DDR). Each channel is comprised of three chips: two digital decimating filters, and a numerically controlled oscillator/modulator. The ICs are interconnected to the MCM substrate by both TAB (tape automated bonding) and gold wire bonding. TAB assembly is used for the VLSI chips in order to be able to pretest these circuits at their maximum operating speed (up to 33 MHz) prior to assembly, substantially reducing die rework. Hypothetical yield models were developed comparing wirebonded, untested die, and TAB'ed, pretested die. The results of these models indicated that a wirebond version could require numerous rework iterations to produce a functional module and be well beyond current MIL STD H-38534 and 1772 rework allowances, not to mention the rework survivability of the MCM substrate. The TAB'ed, pretested model predicted 100% functional modules in two rework cycles.< |

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.
