The Printed Circuit Board (PCB) Layout --- A Tutorial
This project demonstrates how we produce an electronic project using one particular PCB CAD package. Our business is about producing finished custom electronics, and the PCB design process is an important part of that. This page might be of interest to new designers wanting to learn principles, or to potential clients wanting to understand our processes more thoroughly.
The project we have chosen as our example is an RS232 to RS485 converter. This is a often needed device which can demonstrate a lot of principles of circuit design, and hopefully the finished project will be useful to some people, just as it stands. If you just need the RS485 converter without the tutorial, click here.
We start with a specification - to do things "by the book" - we should define our goals and set limits.
