When procurement and assembly are split across separate companies, the assembler receives components it did not ｓｅｌｅｃｔ, inspect, or store. If a part is counterfeit, mislabeled, or stored outside recommended humidity ranges, the problem only surfaces after reflow — by which point rework is expensive and schedules have slipped. Integrating sourcing and assembly within one manufacturer closes that gap.
Farway Electronic, an EMS provider based in LongGang, Shenzhen, operates its own component procurement, incoming quality inspection, and controlled warehousing alongside two SMT production lines. Rather than acting as a passive assembler, the company reviews each customer BOM for sourcing risk, works with authorised brand agents and distributors, and manages materials through an ERP-tracked, first-in-first-out warehouse with anti-static storage and controlled temperature and humidity. This electronic component management system ensures that only verified, correctly stored parts reach the pick-and-place machines.
Key Insight
Counterfeit and grey-market components are a persistent problem in electronics supply chains. When the same manufacturer that sources the parts also assembles and tests the board, traceability is maintained end-to-end, and accountability for quality cannot be shifted between vendors.
A capable SMT line is more than a pick-and-place machine. Farway's SMT production lines are built around Yamaha medium- and high-speed placement machines paired with Jintuo ten-zone reflow ovens, supported by SPI solder-paste inspection, AOI optical inspection, and FAI first-article inspection. This equipment chain catches defects at the point where they are cheapest to fix — before a board moves downstream to coating, testing, or final assembly.
For teams that need a turnkey smt pcb assembly service, this means one contract, one quality standard, and one engineering contact from BOM review through assembled board delivery.
Soldering a board correctly is only half the job. Protecting it and verifying its function are what determine whether the product survives in the field. Farway extends its manufacturing chain with two services that many standalone SMT houses do not offer in-house.
After assembly, boards destined for automotive, industrial, or outdoor applications need protection against moisture, dust, corrosion, and thermal cycling. Farway operates an automated conformal coating line that supports boards up to 550 mm × 470 mm, with selective masking, double-sided spraying, and integrated baking. The line handles dense, high-pin-count assemblies without leaving unprotected areas that would fail in harsh environments.
A robust pcba testing process is what separates a board that powers on from one that performs correctly under real conditions. Farway's testing capabilities span the full inspection spectrum:
| Inspection Stage | Method | What It Catches |
|---|---|---|
| Solder paste | SPI | Insufficient or excessive paste deposition |
| Post-placement | AOI | Misaligned, missing, or tombstoned components |
| Hidden solder joints | X-ray | BGA voids, shorts, and cold joints under packages |
| Circuit integrity | ICT | Opens, shorts, and incorrect component values |
| Functional performance | FCT | Board-level function failures under operating conditions |
| Environmental reliability | High/low-temperature testing | Thermal-stress failures before field deployment |
Farway also backs its testing with a one-year free-repair commitment for eligible non-external defects arising during standard customer use — a level of post-delivery accountability that standalone assemblers rarely match.
Electronics destined for automotive, medical, or safety-critical applications cannot be manufactured on uncertified lines. Farway holds four management-system certifications that map directly to the industries it serves:
The company also works to IPC-A-600H for PCB acceptance and IPC-A-610 for PCBA assembly standards. For hardware teams in regulated markets, these certifications mean that manufacturing documentation, process controls, and traceability systems already exist — reducing the supplier-qualification burden.
An assembled and tested PCBA is not a finished product. Enclosures, wiring harnesses, human-machine interfaces, connectors, and packaging all need to come together — and if these steps are outsourced to yet another vendor, the integration risk returns. Farway's finished-product assembly line integrates tested PCBA boards with mechanical and electrical modules into packaged, barcoded, traceable products under SOP-based production with QC full inspection and QA/OBA sampling.
For new products, the company also offers NPI (New Product Introduction) and DFX (Design for Excellence) support, helping engineering teams identify manufacturability issues before tooling commitments are made. This front-end involvement, combined with prototype-to-volume SMT capability, means a product can move from first prototype through mass production without changing manufacturing partners.
When evaluating an EMS partner for SMT assembly with integrated component sourcing, the following questions help separate capable manufacturers from those that simply broker assembly:
Farway Electronic answers yes to each of these questions. Established in 2018 and operating a 2,000-square-metre production facility in Shenzhen, the company has served more than 100 industry customers across more than 20 countries and regions, with application experience spanning transportation, new energy, security, medical, communication, and consumer electronics.
If your team is managing multiple vendors for component sourcing, SMT assembly, coating, and testing, consolidating under a single accountable partner can reduce lead times, improve quality consistency, and simplify traceability. Farway Electronic provides integrated PCB manufacturing, component management, SMT assembly, conformal coating, PCBA testing, and finished-product assembly from one Shenzhen facility — certified to ISO 9001, ISO 13485, IATF 16949, and ISO 14001 standards.
