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.

We want to be the fastest quick turn prototype electronics manufacturing company, servicing customers who are time and technology focused. We are at $100 million in revenue and are ready to grow even more. We work with tier 1 aerospace and defense companies, all the big brands in tech, and many other innovative companies that are changing the world.

Sierra Circuits has had a presence in Bangalore and Goa since the 90s. Our India operations have been and continue to be critical to the success of Sierra Circuits and our customers. In a quick cycle time environment, our India operations have proven to be a strong differentiator and asset. The Bangalore office strength is around 100 and the Goa office strength has the capacity of 200+ associates. We have created a brand new manufacturing facility set to grow with India’s push into electronics manufacturing. Our culture, as a family-owned business, is to service our customers and our employees with the utmost professionalism. Our Indian offices are not covered by our AS 9100 certification.

We want to do good for the world, through philanthropic work. This work would be funded by the company’s growth. Areas we are currently working on include educating the youth in India, and helping refugees from different parts of the world to America. Together, we can make the world a better place.
