About Us
Innovation is the true spirit of Sierra Circuits.
And the ever-changing demands of the PCB industry continue to fuel this spirit today.
Back in the mid 1980’s, while other manufacturers were simply fabricating circuit boards, Sierra Circuits was constantly reinventing itself while pushing the envelope to help revolutionize the PCB industry. As a family-run business, the idea of establishing quicker cycle times was born out of the existing industry inefficiencies.
Specializing in quick turn PCBs and medium production runs, Sierra’s primary focus is delivering the highest quality product in the shortest amount of time. What makes this possible is that Sierra is the actual manufacturer and assembler of PCBs. By owning our manufacturing and assembly facilities, we control every aspect of the production schedule.
Above all, Sierra Circuits’ creed is to provide customers with resources, knowledge and the highest quality circuit boards the industry has to offer.
