Gerber File Option Added to Sunstone's PCB123 Order Process Sunstone Circuits, printed circuit board (PCB) solutions provider for prototypes, medium volume and production quantities, has launched a better way to get free Gerber files when placing a PCB order through the PCB123 free CAD tool. As always, PCB123 users can easily design and order prototypes and production through Sunstone's full manufacturing service line by clicking on the "ORDER" button inside PCB123 to send the design straight to Sunstone’s OneQuote form to allow the user to make all of the PCB choices they need for their design. In addition to all the normal PCB parameters users also have a choice of engineering level and can either build for Prototype (Limited Review) or jump over to Sunstone's PCBpro service for complex services or full-blown production.
