Printed Circuit Board Assembly and Fabrication Services

South Bay Circuits provides PCB assembly for SMT, through-hole, mixed-technology, fine-pitch, and BGA circuit boards. Capabilities also include RoHS-compliant processing, conformal coating, potting, water-soluble flux, and specialty hand soldering. Programs can range from same-day or three-day prototype builds to production runs, with AOI, X-ray, in-circuit, and functional testing available to support quality verification.

Yes. SBC offers a coordinated path from PCB design and layout support through fabrication, assembly, testing, and box-build services. Keeping these activities under a single source of accountability reduces process handoffs, shipping delays, and communication gaps. The team also performs DFM and DFT evaluations to help designs move more smoothly from engineering documentation into prototype and production manufacturing.

SBC offers same-day, three-day-turn, and standard production options for PCB assembly, depending on design complexity, materials, component availability, testing needs, and production volume. For fabrication, 24-hour options are available for qualifying requirements. Providing complete manufacturing files, an accurate bill of materials, and component sourcing requirements early helps the team evaluate the fastest practical path for your build.

Testing and inspection options include Automated Optical Inspection (AOI), X-ray inspection, In-Circuit Testing (ICT), and functional testing. These methods help identify placement, solder-joint, hidden BGA, electrical, and performance issues at appropriate stages of the build. SBC also provides ERP-based traceability to support controlled production records and more confident quality review for demanding electronic assemblies.

South Bay Circuits is ISO 9001:2015 certified under Certificate #10000903 QM15, valid through August 29, 2027. Its assembly work is supported by IPC-A-610 acceptability standards, and PCB requirements can include IPC-6012 Class III military standards. SBC also maintains ISO 13485 compliance for medical device products, ISO TS 16949 automotive compliance, and AS 9100 aerospace compliance.

Yes. SBC supports electronics programs for aerospace and defense, military, medical, automotive, industrial, and instrumentation markets. The company is ITAR registered and CMMC Level 1 compliant, with quality and process capabilities suited to controlled, complex, and reliability-focused applications. Requirements should be reviewed during quoting so documentation, traceability, testing, and applicable standards can be aligned to the program.

Yes. SBC’s PCB design services include schematic capture, circuit-board design engineering, layout-ready packages, and concurrent engineering support. DFM and DFT evaluations identify manufacturing and test considerations before release, while component sourcing consultation addresses availability and counterfeit-parts avoidance. This early review can reduce NPI cycle time, prevent avoidable revisions, and improve the transition from design into fabrication and assembly.

For an accurate quote, provide Gerber or native design files, fabrication drawings, a bill of materials, assembly drawings, quantities, target delivery date, and any testing or compliance requirements. Include notes on supplied versus sourced components, revision control, and special processes such as coating or potting. SBC can then review manufacturability, material needs, turnaround options, and the appropriate production path.
