Sierra Circuits, Inc.

Sierra Circuits is an ISO 9001:2008, ISO 13485:2003 and MilSpec MIL-P-55110 certified, Silicon Valley-based, high-technology Printed Circuit Boards manufacturer and Assembler. We specialize in quick turn PCBs and medium production. Unlike some PCB companies that are simply brokers/middlemen, we are the actual manufacturer and assembler of our PCBs. By owning our manufacturing and Assembly facilities, we control every aspect of the production schedule and quality. And this is why we can provide our customers unprecedented quality, reliability and a single point of support.

We continuously update our capabilities and equipment, like sophisticated direct imaging machines, enabling us to do reliable and repeatable 4 / 4 with an aspect ratio of 10. We make up to 22 layers on a .185-inch thick board. Our high technology boards have features like Blind/buried vias, filled vias (hole in pads), controlled impedance, high aspect ratios and micro-BGAs. We regularly make specialty products like Lead-free boards, Burn-in Boards, Polyimide multi-layers, Thermount multi-layers, Metal Core PCBs, carbon paste, and boards with blind/buried vias, filled vias and micro vias. Our latest offerings include Microelectronics PCBs, down to 1 mil trace & space.
