PCB is an interactive printed circuit board editor for the X11 window system. PCB includes a rats nest feature, design rule checking, and can provide industry standard RS-274-X (Gerber), NC drill, and centroid data (X-Y data) output for use in the board fabrication and assembly process. PCB offers high end features such as an autorouter and trace optimizer which can tremendously reduce layout time.

Printed Circuit Board Considerations - Basics of PCB Transmission Lines is a TechXclusive by Peter Alfke, Director of Applications Engineering, focusing on PCB design considerations.

It's Not Your Father's PCB Anymore... is a TechXclusive by Austin Lesea, Principal Engineer, explaining the necessity of signal integrity analysis. It would be nice if SI engineering was not necessary, but unfortunately, it is needed now more than ever if you need to save time and money, and you need to get things to work reliably -- and not just for FPGAs.

Printed Circuit Board Modeling Issues is a TechXclusive by Austin Lesea, Principal Engineer, stating that FPGAs do not really represent a major change in the way printed circuit boards are designed, but at the speeds FPGAs can now operate, printed circuit board design becomes a major part of a successful product. It explains how to account for PCB properties when evaluating your system's performance.

PCB - Copper Printed Circuit Boards
Solderless breadboards are the fastest and most flexible way to design and experiment. When the circuit is ready for more permanent use, there are several methods of connecting components together that are appropriate for one-time designs in robots. Point-to-point soldering can result in a rat's nest problem. Homemade printed circuit boards are a good solution.

I purchased and read the wonderful book Making Printed Circuit Boards. The book covers much more than is described on this page. I highly recommend you read the book before attempting to make your own circuit boards.

Choosing a Sample Circuit

Although I eventually want to use surface-mounted components and double-sided circuit boards, I decided to eliminate additional new variables for my first attempt. I limited the first project to through-hole components (such as standard DIPs) on a single-sided circuit board.

I'm experienced with through-hole components and I've soldered 0.1-inch point-to-point perf boards. I saved myself a lot of trouble and frustration in learning a new technology by building on top of what I already know well.

The chosen circuit isn't important, although it should be fairly simple for your first attempt. I decided to create a daughterboard that contains complete circuits for a voltage regulator and two DC motor drivers (H-bridge motor driver) for Sweet, a line-following robot. This board includes resistors, small DIP sockets, capacitors, a switch, an LED, Molex connectors, diodes, a jumper, and a few crossover wires. An excellent variety of common components with which to experiment!

Free CAD Software

Before writing this web page, I'd never used a PCB CAD layout program before. I don't own any PCB CAD software and I didn't want to pay hundreds of dollars to buy a package. One popular freeware choice is CadSoft Eagle.

ExpressPCB also has free Windows OS software that is quite good and easy to get started with. The advantage to using their software and mini-board size is that, if desired, you can order professionally made boards, 3 for $59 (the price has varied slightly over the years). This is a nice deal for robot hobbyists that don't need production quantity runs. Their boards are of higher quality (greater accuracy, plated through holes, and tin coating) than is usually possible to make at home. Over the years, I've ordered over a thousand boards from ExpressPCB and have been very pleased with their on-time service, reasonable prices, and excellent product. (No, I don't get any special deals or discounts.)

The ExpressPCB online help is written with beginners in mind, the internet ordering option is convenient, the software has never crashed on me, and they update the software regularly with new features.

The disadvantage to using their software is that its breadth of capabilities and components library are somewhat limited, although you can create custom components. Also, you're stuck with their file format, which is a problem if you want to order production boards from someone else.

For all the positive reasons, I chose to use the free ExpressPCB software, and I happily continue to do so to this day.

Avoiding False Starts

When trying to design a circuit, I got overwhelmed on the first couple of attempts. I discarded several windows and files. I was trying to make too large of a leap by designing with surface-mounted components, two-sided boards, components on both sides, and very thin traces.

To get beyond this mental obstacle, I designed the circuit by physically laying out components on an ordinary perf board with pre-drilled holes every tenth of an inch. Then I copied the patterns into the ExpressPCB software and switched back-and-forth as the circuits progressed. On the screen I could see efficient changes, which I then tried on the physical layout. Sometimes I would notice a problem on the physical layout that I needed to correct on the screen.

I worked on a single functional unit at a time (like the voltage regulator) and only proceeded after I had perfected that section. This allowed me to experiment, apply, and learn layout skills without having to go back and throw out a lot of prior work.Design and Fabricate Custom Printed Circuit Boards - PCB ' s - Online at Pad2Pad!
