Substrate & PCB Design

Miniaturization of components and increasing of signal speeds on all kinds of circuits has been governed as much by the ability of reliable printed circuit board (PCB) fabrication and manufacturing technology as it has been by the ability to produce the small components. Accuracy of layer registration, controlling substrate layer thicknesses for impedance, constructing dependable buried vias, and generating solder masks that guarantee components will self-align without allowing solder bridging or component tombstoning have all been significant challenges.

Simple circuits can still be handled with decades old layout and construction techniques, but if you are beyond that level, then some serious learning needs to be done for adopting best practices that will help assure first-pass success. These resources will help you get there with a minimum of pain. In many cases, PCB companies can turn your schematics into a finished PCB, and often can carry it into production. Please consider RF Cafe advertisers first when investigating services.

PCB Design
pcbdesign.org
The Internet's ultimate resource offer a PCB design guide to help you get started today with your first printed circuit board design. PCB Design can be frustrating, time consuming, and very difficult to figure out where to start. We've broken PCB design into 3 sections: schematic capture, PCB footprints, and PCB-layout. Our PCB design guide will also help you figure out which is the best PCB design software to use, whether your project is a hobby or a commercial product. If you've run out of time and looking for a PCB design service we can also help you navigate that process.
