Abstract | Summary form only given, as follows. Many new types of ball grid array packages have been introduced or proposed in the last year as alternatives to PQFPs and PGAs. These include single and multilayer configurations for both plastic and metal BGAs based on a variety of material and process technologies. A commonly claimed advantage of all these BGAs is improved electrical performance. With continued increases in clock speed and reductions in noise margins due to voltage scaling, electrical performance will become a driving force for introduction of BGAs in many products. A detailed study of the electrical performance of a selected set of single and multilayer BGA packages was completed. The different package models were generated using a field solver and analyzed for their signal integrity characteristics using SPICE. This includes an analysis of how closely the output signals and the input signals match under varying load conditions. The design and performance of the selected BGA packages were then assessed based on initial simulation results, and a set of design guidelines to optimize electrical performance were developed. These design guidelines can then be applied based on product needs. This paper will address the electrical performance and relative complexity and cost factors facing the engineer and suggest optimal choices for the varying load conditions and chip types. |

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.
