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
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

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.
