An Interactive Layout System for Analog Printed Wiring Boards

Apart from the layout of digital printed wiring boards (PWB´s), no specific development has yet been reported on the layout of analog PWB´s, which requires not only placement and routing but also artwork to generate a variety of geometric wire patterns and assembly drawings. An interactive artwork system for analog PWB´s is described, which consists mainly of two programs; one for generating wire patterns and the other for generating assembly drawings. This system is in production use and has greatly reduced the time and cost incurred in laying out wire patterns on analog PWB´s.
