PCB Assembly Services — Surface Mount & Through-Hole

A PCB assembly is a printed circuit board that has been populated with electronic components and prepared for use in a device or system. Assembly can include surface mount technology, through-hole components, mixed technology, BGAs, conformal coating, potting, cleaning, inspection, and testing. SBC supports both prototype and production PCB assembly with single-source control from design through loaded board manufacturing.

PCB cost is driven by board complexity, layer count, size, component availability, assembly type, quantity, testing requirements, and turnaround time. A simple prototype typically costs less than a dense mixed-technology build with BGAs, coatings, or specialized compliance requirements. SBC helps reduce total cycle time and cost by coordinating design, fabrication, assembly, and production support under one source.

PCB assembly usually begins with design and manufacturability review, followed by material sourcing and board fabrication. SMT components are placed and reflow soldered, through-hole parts are inserted and soldered, then the assembly is inspected, cleaned, coated or potted if required, and tested. SBC supports these steps with quick-turn capability and controlled in-house processes.

SMT assembly places compact components directly onto the board surface, making it ideal for high-density electronics and automated production. Through-hole assembly inserts component leads through drilled holes, often used for connectors, power components, and parts needing stronger mechanical attachment. Many modern products use mixed technology, combining both methods on the same PCB assembly.

SBC offers 3-Day Turn or Less PCB assembly for time-critical projects when design files, materials, component availability, and production requirements align. The company’s single-source model helps reduce queue time between design, fabrication, and assembly. For more complex builds involving BGAs, coatings, potting, or special testing, timelines are confirmed after reviewing the complete project package.

Yes. SBC supports prototype builds, new product introduction, and production assembly, allowing customers to move from early validation to larger production without switching suppliers. This continuity helps reduce NPI and NPD time, limits handoff errors, improves accountability, and supports a smoother transition from engineering builds to repeatable manufacturing.

SBC supports quality requirements for industrial, medical, instrumentation, aerospace and defense, automotive, and military applications. Credentials include ISO 9001:2015 certification, ISO 13485 compliance for medical device products, ISO TS 16949 automotive compliance, AS 9100 aerospace compliance, ITAR registration, and CMMC Level 1 compliance, depending on the project requirements.

A strong PCB assembly quote package typically includes Gerber files, fabrication drawings, assembly drawings, bill of materials, pick-and-place data, testing requirements, quantities, target delivery date, and any coating, potting, cleaning, or packaging instructions. Providing complete documentation helps SBC review manufacturability, confirm component sourcing, identify risks early, and recommend cost or cycle-time improvements.
