Computer-aided process preparation for printed wiring boards
A pilot computer project using CAD-CAM software, and a graphics terminal is integrating design, process preparation, and increasingly, the manufacture of printed wiring boards through automation. A CAD-CAM data base has been used to compare critical design features to statistical process models to predict yield before production begins. The on-screen display of digital design definitions has been shown to contribute to greater, more predictable and reliable yields for complex multilayer and double-sided designs. Engineers are able to identify and correct manufacturing problem areas and predict risk before production. This project indicated that use of computer graphics and CAD-CAM software to fabricate printed wiring boards not only increases accuracy of yield but also reduces engineering time required for manual procedures.
