Sierra Protoexpress

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. We specialize in quick turn PCBs and medium production. Unlike some PCB companies that are simply brokers/middlemen, we are the actual manufacturer of our PCBs. By owning our manufacturing facilities (in California and Kansas), 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.

Product Name: Burn-in Boards
Product Category: PCB Manufacturing - PCB Design Tools

Burn-In Boards are boards that are used in the process of electrically stressing a device at an elevated temperature, for a sufficient amount of time to cause the failure of marginal devices (Infant Mortality).

Product Name: Lead Free PCBs / ROHS & WEEE Compliant
Product Category: PCB Design and Analysis - PCB Design Tools

The main thrust of the RoHS requirement is that 6 hazardous substances may not exceed strict limits set by these directives. These substances are lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl and polybrominated biphenyl ethers. These substances are limited to 1000 parts per million (0.1%) with the exception of cadmium which is restricted to 100 parts per million (0.01%). For the printed circuit board industry the restrictions on lead and polybrominates (used as flame retardants in plastics, i.e. epoxy resins) are far reaching.

Product Name: Mil-spec PCBs
Product Category: PCB Manufacturing - PCB Design Tools

Sierra Proto Express is qualified by the USA Department of Defense to MIL- PRF-55110F for GF (FR4) and GI (Polyimide) Printed Circuit Boards.

Sierra Proto Express has an extended history of manufacturing High Rel printed circuit boards to MIL-PRF-55110 F. We have in-house capability to provide Group A testing that is required for Mil-Spec PCB boards.

Product Name: PCB Assembly Services
Product Category: PCB Manufacturing - PCB Design Tools

Sierra Circuits, Inc. has been a leading manufacturer of PCBs for over 25 years. We also provide PCB Assembly Services, so our customers can get the one-stop convenience and single point of support for both PCB Manufacturing and Assembly.

Product Name: Web PCBs
Product Category: PCB Design and Analysis - PCB Design Tools

Our new promotion, Web PCBs, is the fastest and most convenient way for you to get PCBs online.
