Printed Circuit Board Prototype Solutions

While hobbyists can etch simple PCBs at home, professional prototypes require precision fabrication equipment, controlled processes, and quality testing that most individuals and companies don't have in-house. South Bay Circuits provides full design, layout, fabrication, and assembly services, ensuring your prototype meets IPC standards and is ready for reliable testing and scale-up.

South Bay Circuits, headquartered in a 60,000+ sq ft facility in Chandler, Arizona, offers domestic PCB prototype design, fabrication, and assembly with same-day and 24-hour turnaround options. As an ISO 9001:2015-certified, ITAR-registered manufacturer, SBC serves customers across the U.S., including Texas, Florida, California, and New York.

SBC offers some of the fastest turnaround times in the industry, including same-day PCB assembly, 24-hour fabrication, and immediate-response design services. Standard and quick-turn options are available depending on design complexity, layer count, and volume, letting you move from concept to tested prototype in hours or days rather than weeks.

South Bay Circuits supports single-sided, double-sided, and multi-layer boards up to 22+ layers, including HDI designs with blind and buried vias, controlled impedance, and fine-pitch BGA assembly. Trace/space capabilities down to .002"/.002" allow for complex, high-density prototype layouts across a wide range of applications.

Yes. SBC provides PCB design engineering, quick-turn layout services with 24-hour turnaround, Design for Manufacturability (DFM) and Design for Testability (DFT) evaluations, and component sourcing consultation. This concurrent engineering support helps optimize your prototype for both performance and a smooth transition to volume production.

Prototypes are built to IPC-A-600 and IPC-A-610 workmanship standards, with military-grade options meeting IPC-6012 Class III. SBC is ISO 9001:2015 certified, ITAR registered, and CMMC Level 1 compliant, with quality assurance including AOI, X-Ray inspection, In-Circuit Testing, and Functional Testing backed by full ERP traceability.
