An Integrated Design Environment For Printed Wiring Boards

M. Rosman and M. Osterman


AlliedSignal has implemented an integrated design environment for design, analysis, prediction, and optimization of printed wiring boards.  The goal is to make reliability and maintainability an integral, real-time, and upfront part of the design process, such that the need to resubmit designs will be eliminated.  The integrated design environment uses a powerful, modular, and integrated set of user-friendly tolls for the design and analysis of Printed Wiring Board Assemblies (PWAs).  The software provides databases of materials and components.  Modeling tools include a board definition tool and a component selection and placement tool.  Analysis tools include thermal vibration and shock, solder joint fatigue, Plated Through Hole (PTH) fatigue, and component derating.
