Reliable Printed Circuit Board Assembly Manufacturer

South Bay Circuits provides surface-mount technology (SMT), through-hole, mixed-technology, fine-pitch, and BGA assembly. Additional capabilities include hand soldering for specialty components, RoHS-compliant processing, conformal coating, potting, and water-soluble flux options. These capabilities support prototype, new-product-introduction, and production requirements for industrial, medical, automotive, aerospace, defense, and military electronics programs.

Yes. SBC supports same-day and three-day-turn prototype builds as well as standard production runs and high-volume programs. Its Chandler assembly operation provides domestic process control for responsive builds, while strategic offshore production partnerships expand capacity for lower-cost, higher-volume requirements. This approach helps customers move from prototype validation to scaled manufacturing without changing manufacturing partners.

SBC integrates Automated Optical Inspection (AOI), X-ray inspection, In-Circuit Testing (ICT), and functional testing into its PCB assembly support. The appropriate methods depend on component density, hidden solder joints, test-point access, and end-product requirements. Assembly records are maintained through the SBC ERP system, giving customers traceability across the manufacturing process and helping identify issues before finished boards move forward.

Turn time depends on board complexity, component availability, quantity, testing requirements, and any specialty processes. SBC offers same-day, three-day-turn, and standard-production options for PCB assembly. To establish a realistic schedule, the team reviews Gerber and assembly files, bill of materials, approved alternates, component lead times, and the required inspection or test plan before production is scheduled.

SBC is ISO 9001:2015 certified and builds assemblies using IPC-A-610 acceptability criteria. The company also supports IPC-6012 Class III military PCB standards and is ITAR registered, with CMMC Level 1 compliance stated for its defense manufacturing operations. Its quality framework is designed to promote controlled processes, inspection discipline, documented traceability, and continual improvement across complex electronic manufacturing programs.

Yes. SBC supports BGA, fine-pitch, and high-density assembly requirements. These package types demand disciplined component placement, solder-profile control, and inspection because solder connections may be small or concealed beneath components. SBC’s assembly capabilities include X-ray inspection, which is particularly useful for evaluating hidden solder joints in BGA packages and other dense electronic assemblies.

Yes. SBC offers PCB design services that include schematic capture, circuit-board design engineering, layout-ready packages, Design for Manufacturability (DFM), and Design for Testability (DFT) evaluations. Early collaboration can identify component sourcing concerns, manufacturability risks, and cost-reduction opportunities. Aligning design decisions with downstream fabrication and assembly helps reduce New Product Introduction cycle time and avoid preventable production changes.

A useful PCB assembly quote package typically includes Gerber or fabrication files, assembly drawings, a bill of materials, component specifications, quantities, required delivery date, and testing or inspection requirements. Note any special needs such as conformal coating, potting, RoHS processing, ITAR handling, or box-build work. Complete documentation enables SBC to review manufacturability, sourcing, labor, testing, and schedule requirements accurately.
