PCB Assembly Services in California

South Bay Circuits provides surface-mount technology (SMT), through-hole, mixed-technology, fine-pitch, and BGA assembly. The company also supports RoHS-compliant builds, conformal coating, potting, water-soluble flux processes, and hand-soldering for specialty components. These capabilities allow a single production partner to support straightforward circuit cards as well as dense, complex assemblies for industrial, medical, automotive, aerospace, and defense applications.

SBC offers same-day, three-day-turn, and standard production options, depending on the build requirements, material readiness, testing needs, and production volume. Same-day capability is especially useful for urgent prototype and development programs. Before scheduling a build, the team reviews documentation, component availability, board requirements, and inspection needs so the requested turnaround is achievable and clearly defined.

Yes. South Bay Circuits supports quick-turn prototype assemblies through high-volume production runs. This continuity helps teams transition from an initial build to repeatable manufacturing without changing assembly partners or recreating process knowledge. SBC can also coordinate related design, fabrication, testing, and box-build services, helping maintain control as a product moves through NPI and into ongoing production.

Available testing and inspection services include automated optical inspection (AOI), X-ray inspection, in-circuit testing (ICT), and functional testing. The right combination depends on package types, board density, product risk, and verification requirements. BGA and other hidden solder joints can benefit from X-ray inspection, while functional testing verifies how the completed assembly performs in its intended operating condition.

SBC’s assembly work is supported by ISO 9001:2015 certification and IPC-A-610 acceptability standards. The company also lists IPC-6012 Class III military PCB standards, ITAR registration, and CMMC Level 1 compliance for relevant controlled programs. In addition, SBC identifies compliance capabilities for ISO 13485 medical device products, ISO TS 16949 automotive requirements, and AS 9100 aerospace requirements.

Yes. South Bay Circuits supports customers across California through remote design collaboration and managed manufacturing coordination from its Chandler, Arizona facility. Teams can provide design files, bills of materials, assembly documentation, and test requirements for review. This approach gives California organizations access to a centralized PCB fabrication and assembly resource without needing to manage separate vendors for each stage.

A useful assembly quote typically starts with Gerber or ODB++ data, a bill of materials, pick-and-place data where applicable, assembly drawings, quantities, target turnaround, and testing requirements. Details such as component sourcing preferences, special processes, conformal coating, and traceability expectations should also be included. Complete documentation helps identify manufacturability issues early and supports more accurate scheduling and pricing.

Yes. South Bay Circuits offers PCB design services, including schematic capture, layout support, design-for-manufacturability (DFM), design-for-testability (DFT), and component sourcing consultation. Reviewing these factors before fabrication and assembly can reduce avoidable revisions, improve production readiness, and shorten the time between a design release and a completed, tested circuit-card assembly.
