Popis: The development and deployment of very fast signaling technologies for communication across the backplane has introduced the need for a multidisciplinary design approach where the performance of the silicon to silicon communication channel is addressed from a variety of different perspectives. SerDes technology, connectors, vias, via stubs, and board materials are among the elements that need to be considered and modeled to reach-the desired trade off with respect to performance, cost and quality. In this study, component and system level electrical performance with back-drilled (or Counter Bored) Plated Through Holes is investigated, with simulation and testing examples. The methodology that is presented leverages multidisciplinary aspects of design and puts quality as a key ingredient of the development process. The results of this work and the associated methodology have been successfully shared across Business Units and Technology Groups.
