Computer-aided process preparation for printed wiring boards
Abstract
A pilot computer project using CAD-CAM software, and a graphics terminal which intergrates design, process preparation, and manufactures printed wiring boards through automation is described. A CAD-CAM data base was used to compare critical design features to statistical process models to predict yield before production begins. The onscreen display of digital design definitions is shown to contribute to greater, more predictable and reliable yields for complex multilayer and double sided designs. It is indicated that use of computer graphics and CAD-CAM software to fabricate printed wiring boards increases accuracy of yield and reduces engineering time required for manual procedures.
