Expert PCB Fabrication and Assembly Services

Custom PCB cost depends on board complexity, layer count, material selection, dimensions, component availability, assembly technology, testing requirements, and turn time. Quick-turn prototypes usually cost more per unit than standard production because engineering, setup, and expedited labor are compressed. South Bay Circuits provides pricing on request and can quote same-day, 3-day-turn, standard, and volume production options.

A custom PCB is a printed circuit board designed for a specific electronic product, system, or application rather than an off-the-shelf circuit. It can include unique circuitry, board shape, layer stackup, materials, component placement, and performance requirements. SBC supports custom PCB programs from schematic capture and layout through fabrication, assembly, inspection, testing, and production scaling.

PCB fabrication creates the bare printed circuit board, including copper layers, drill holes, plating, solder mask, and surface finish. PCB assembly adds electronic components to that board using SMT, through-hole, mixed-technology, hand soldering, and related processes. South Bay Circuits supports both, helping customers avoid delays and miscommunication between separate vendors.

SBC offers same-day PCB assembly, 3-day-turn prototype builds, and standard production options depending on the project scope, materials, component availability, and test requirements. PCB fabrication can be supported on expedited schedules, including 24-hour board fabrication capabilities. For best results, provide complete design files, BOM, assembly drawings, and special instructions early.

SBC works with industrial, medical, instrumentation, aerospace and defense, automotive, and military customers. The company supports quality-sensitive and regulated applications with ISO 9001:2015 certification, ITAR registration, CMMC Level 1 compliance, and standards-driven assembly practices. Capabilities include prototype development, new product introduction, quick-turn builds, and scalable production programs.

Testing options include Automated Optical Inspection, X-Ray inspection, In-Circuit Testing, and Functional Testing. These services help verify solder quality, component placement, hidden BGA connections, circuit continuity, and product-level performance. SBC also maintains traceability through its ERP system, helping customers document builds and improve quality control across prototype and production runs.

Yes. South Bay Circuits provides turnkey PCB design, layout, fabrication support, assembly, testing, and box build services. Having these functions under one accountable source can reduce queue time, shipping delays, engineering handoff issues, and supplier blame. It also helps teams move faster from new product development to reliable manufacturing.

SBC supports both prototype and production needs. Customers can use quick-turn services for engineering validation, design revisions, and NPI schedules, then transition into higher-volume production through domestic capabilities and offshore volume production partners. This approach helps maintain continuity while balancing speed, cost, quality, and production scalability.
