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 Circuits’ primary focus is delivering the highest quality product in the shortest amount of time. What makes this possible is that we are 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.

True quality comes by default from an elegant, well-designed process.
We’re proud to boast that a Sierra Circuits PCB is on display at the National Air and Space Museum in Washington D.C.

Engineered for strength, one of our cubesat boards not only survived a catastrophic explosion onboard a client name redacted rocket, but was the only thing that was left undamaged after everything came crashing back to earth.
It’s worth noting that our cubesat board was not the cause of the explosion.

Sierra Circuits builds exceptional PCBs for a truly global market.
