SMT PCBA Assembly Solutions by SFX PCB

SMT (Surface Mount Technology) PCBA assembly involves placing and soldering electronic components directly onto the surface of a printed circuit board using automated pick-and-place machines and reflow ovens. Through-hole (THT) assembly inserts component leads through drilled holes and solders them on the underside. SMT enables smaller, denser boards, while THT offers stronger mechanical bonds. SFX PCB handles both technologies independently or combined in mixed assemblies.

SFX PCB adheres to IPC-A-610 Class 2 and Class 3 workmanship standards—the globally recognized benchmark for PCB assembly quality. All assemblies also undergo 100% AOI (Automated Optical Inspection), X-ray inspection for BGA and hidden solder joints, and functional testing (FCT). Our facilities are ISO 9001 and ISO 13485 certified, and all products are RoHS and REACH compliant for global market access.

Prototype PCB assembly orders can receive a quote within one business day of submitting Gerber files and BOM. Once all components are available, boards can be assembled in as little as 24 hours. Standard delivery for most prototype and quick-turn orders is 1–2 weeks. Expedited options are available for urgent requirements, though additional charges may apply for rush shipping beyond standard lead times.

SFX PCB offers full component sourcing and procurement as part of its turnkey service. Our experienced sourcing team has access to over 600,000 items in local stock, helping minimize lead times and reduce costs through bulk buying power. When components are unavailable or costly, we suggest approved alternative parts—always with your sign-off before substitution—to keep your project on time and within budget.

A Design for Manufacturability (DFM) review is a free engineering analysis of your Gerber files and BOM before production begins. Our engineers identify potential issues such as footprint mismatches, insufficient trace widths, stack-up errors, and pad-to-pad spacing violations. Catching these problems before fabrication saves you from expensive respins and delays. SFX PCB provides this analysis at no charge with every order as standard practice.

Yes. SFX PCB is ISO 13485 certified for medical device manufacturing quality management. We assemble PCBs meeting biocompatibility requirements and stringent regulatory standards required for medical applications. Our Parylene nano-vacuum coating technology is also biocompatible and suitable for medical-grade waterproofing. We serve clients across medical equipment manufacturing, health monitoring, telemedicine, and medical robotics with full compliance documentation support.

SFX PCB accommodates flexible order quantities—from small prototype batches of a single board or just a few units all the way up to high-volume mass production. Our Low Volume PCB Assembly service is specifically designed for startups, SMEs, and specialized applications needing 10 to a few hundred boards. There is no requirement to commit to large minimum orders, making us ideal for innovation-driven teams at any production stage.
