Abstract | The requirement for low cost, small size and high density for high-speed system drives the design of packages to smaller package size. ULTRA CSP is an advanced technology to meet the above targets. ULTRA CSP is a wafer level package developed by FCT. Under high frequency operation, the parasitics associated with the package will significantly degrade the package performance. An unsuitable package may cause resonance, coupling, impedance mismatch and frequency dependent loss. So, providing accurate package parasitics is critical to the success of the system design. In this paper, the electrical model of ULTRA CSP has been established based on the S-parameter simulation. When compared with the TSOP package, ULTRA-CSP shows smaller parasitics in the equivalent model. This paper also compares the performance of the ULTRA-CSP and Standard TSOP from the view point of propagation delay, crosstalk noise, insertion loss, return loss and maximum allowable working frequency. Based on the analysis result, is provided the package layout guideline for designer reference. |

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.
