Whatever kind of circuit board you?re building, PCB123 takes you all the way from designing to ordering. A start-up wizard offers several choices for your board, including number of layers, use of plane layers, and solder mask and silk screen. Next, PCB123 presents a CAD design window, and it?s time to go to town. PCB123 has an extensive library of parts, devices, and layouts, and can import net lists from CAD vendors. We found the component search efficient and easy, and editing component properties took only a few clicks. New libraries can be downloaded from the developer?s site. There?s even a 3D display. Pricing is constantly updated based on the current design, and you can order boards from PCB123.
