Chapter 4
PCB Design / CAD

This chapter describes how to use the Layout Editor, the Autorouter, the CAM Processor and CAM View for creating layout library symbols and designing PCB layouts and for generating and processing CAM output and manufacturing data for the PCB production. The examples presented in this chapter introduce the concepts and advanced features of the BAE PCB design system in a logical sequence and will take the user from the creation of layout library symbols and the design and modification of a PCB layout through to the generation of manufacturing data for the PCB production. The PCB design example is based on the circuit drawing and net list data prepared in the preceding chapters and will be subject to further processing in the following chapter. The reader should work through this chapter without missing any sections to gain full understanding of the BAE PCB design system. Once a command has been used and/or explained, the operator is assumed to have understood its function and be able to perform it again. Subsequent instructions containing this command will be less verbose for easier reading and more speedy learning.
