Printed Circuit Board Assembly Services California

PCB assembly cost is based on the board design, quantity, component count and availability, assembly technologies, testing needs, and whether PCB fabrication and box build are included. Cir-Q-Tek provides quotes rather than a fixed price list. To prepare a PCBA quote, provide a Gerber package or ODB file and a bill of materials (BOM). This allows the team to evaluate sourcing, manufacturing, and assembly requirements accurately.

California electronics companies can work with Cir-Q-Tek for turnkey PCB assembly support. Cir-Q-Tek serves domestic customers throughout the United States through its U.S. operations and coordinated overseas manufacturing resources in Shenzhen. The company supports PCB manufacturing, component procurement, SMT and through-hole assembly, inspection, testing, box builds, and packaging for prototype and production programs across multiple industries.

Turnkey PCB assembly combines the major steps needed to deliver a completed electronic assembly through one source. Cir-Q-Tek’s offering includes PCB manufacturing, electronic component purchasing, SMT chip processing, through-hole assembly, testing, complete box build assembly, and packaging. Consolidating these activities can reduce handoffs between suppliers and give your team a more coordinated path from design files to finished product.

Yes. Cir-Q-Tek supports small prototype orders as well as production quantities, helping teams validate designs before scaling manufacturing. The company’s PCB capabilities include quick-turn prototypes, while its PCBA service is configured for sample and small-batch production alongside larger requirements. Sharing complete Gerber or ODB files and a BOM early helps align sourcing, assembly, and delivery planning with your program.

Cir-Q-Tek’s SMT equipment supports fine-pitch and miniature electronic components, including 01005 packages, QFN, CSP, and BGA components with spacing down to 0.2 mm. Each SMT line includes automated optical inspection and X-ray equipment for inline inspection. These capabilities are valuable when assemblies require dense layouts, hidden solder joints, or a controlled inspection approach for complex component placements.

Yes. Cir-Q-Tek includes testing within its full PCBA service suite and uses inline automated optical inspection and X-ray equipment on each SMT line. AOI helps inspect visible assembly features, while X-ray inspection is useful for evaluating solder connections that cannot be visually assessed, such as those beneath BGA packages. Testing requirements should be defined during quoting so the assembly plan reflects your product needs.

Cir-Q-Tek’s procurement team can source obsolete or hard-to-get parts and equivalents for assembly applications. Component sourcing is evaluated as part of the BOM review, so accurate manufacturer part numbers, approved alternates, and quantity requirements are important. Early review can identify availability concerns before production and help the team consider sourcing options that align with the assembly and delivery plan.

Cir-Q-Tek’s manufacturing capabilities are supported by ISO 9001:2015 quality management certification, ISO 13485 for medical device manufacturing, and IATF 16949 for automotive manufacturing requirements. The company also holds UL and cUL approvals and ISO 14001 certification. These credentials support customers whose products require documented quality systems and manufacturing processes suited to regulated or performance-critical applications.
