A true turnkey arrangement means the manufacturer takes responsibility for every step from bare board fabrication through final boxed product, not just the surface-mount soldering step. When a single partner handles PCB manufacturing, component sourcing, SMT placement, through-hole welding, conformal coating, testing, and final assembly, communication overhead drops and accountability stays in one place. If a field failure surfaces months later, there is no debate about which supplier caused it.
Farway Electronic, established in 2018 and operating a 2,000-square-metre workshop in LongGang, Shenzhen, structures its business around this full-chain model. The company presents nine core manufacturing services, from PCB board making and component management through SMT, DIP plug-in welding, PCBA OEM, conformal coating, low-pressure injection moulding, PCBA testing, and finished product assembly. This breadth is what allows the company to position itself as your one stop oem odm pcb pcba manufacturer, covering prototype runs from a single piece up to large-volume production.
The bare board is the foundation of every assembled product. Before evaluating assembly services, confirm that the manufacturer can produce boards to your layer count, material type, and dimensional requirements. Farway's published process capability covers rigid, flexible, and rigid-flex constructions from 1 to 32 layers, working with materials including FR-4, CEM-3, Rogers, Teflon, high-Tg, ceramic, halogen-free, and mixed-pressure laminates.
| Capability | Published Value |
|---|---|
| Maximum PCB size | 850 mm x 520 mm |
| Board thickness | 0.2 mm to 8 mm |
| Copper thickness | 1/3 oz to 15 oz |
| Minimum aperture | 0.15 mm |
| Minimum line width / spacing | 0.05 mm / 0.05 mm |
| Impedance-control accuracy | plus or minus 5% |
Surface finish options listed on the site include lead-free HASL, OSP, ENIG, electrical gold, immersion tin, and immersion silver. For teams working with RF or high-frequency designs, the ability to source Rogers and Teflon materials from the same partner that assembles the board eliminates a coordination layer that often introduces delays.
Surface-mount technology is where most assembly defects originate or are prevented. The equipment set and process controls at the SMT stage directly determine yield rates. Farway operates two SMT production lines equipped with Yamaha medium- and high-speed placement machines and Jintuo ten-zone reflow soldering equipment. The placement capability extends down to 01005 components and handles BGA with 0.2 mm pitch, along with QFN, CSP, and other fine-pitch packages.
For buyers evaluating smt contract manufacturing, the critical question is not just what components the line can place but what happens immediately after placement. Farway runs SPI solder-paste inspection and AOI optical inspection on the SMT line, along with FAI first-article inspection, to catch defects before they propagate downstream. This inspection-embedded approach matters far more than headline placement speed when you are scaling from prototype to mass production.
Many products combine surface-mount components with through-hole parts such as connectors, large capacitors, and transformers. A manufacturer that only excels at SMT but treats DIP as an afterthought can create a quality bottleneck at exactly the point where mechanical stress is highest. Farway dedicates two DIP plug-in production lines to through-hole assembly, equipped with Nitto wave-soldering equipment, 24 rear-welding stations, and a board-washing machine.
The published DIP process runs from component forming and insertion through wave soldering, lead cutting, repair welding, board washing, and functional testing. Plug-in AOI and IPQC and QA sampling are built into the flow. For mixed-technology boards, this integrated SMT-plus-DIP capability under one roof prevents the scheduling gaps and shipping damage that occur when boards move between separate facilities.
If your product will face moisture, dust, vibration, or temperature extremes, conformal coating and low-pressure injection moulding are not optional extras but core reliability measures. Farway runs an Anda automated conformal-coating spraying line that supports boards up to 550 mm by 470 mm, with selective masking, double-sided spraying and baking, and both fan and needle spraying modes. Average spraying time runs 0.5 to 3 minutes per board.
Understanding conformal coating and its role in product longevity helps buyers specify the right protection level. The coating guards against moisture ingress, leakage current, mechanical shock, dust, corrosion, and thermal cycling. For more demanding applications, Farway also offers PCBA low-pressure injection moulding, which encapsulates sensitive components such as medical sensors, LED modules, battery packs, connector harnesses, and microswitches in a durable protective shell. Four low-pressure injection moulding machines support this service, covering applications from medical and industrial sensors to automotive electronics.
A factory that assembles boards but does not test them is handing you unverified risk. The testing methodology a partner employs tells you how likely defects are to reach your customers. Farway's inspection and testing program, operating under IPC-oriented controls, includes the following stages:
Beyond these inspection stages, Farway states a one-year free-repair commitment for eligible non-external defects arising during standard customer use. This post-shipment warranty is a concrete signal of manufacturing confidence, not just a marketing phrase.
Generic ISO 9001 certification is a baseline, not a differentiator. What separates a capable EMS partner from a commodity board house is industry-specific certification. Farway holds four management-system certifications that map directly to the industries it serves:
The company also lists UL, RoHS, SGS, and REACH within its product-certification scope and identifies IPC-A-600H as the PCB implementation standard and IPC-A-610 as the PCBA assembly standard. These certifications matter because they require documented, audited processes, not just a one-time product test.
The final step in a turnkey relationship is finished product assembly, where tested PCBA boards are integrated with enclosures, wiring harnesses, human-machine interfaces, connectors, and mechanical modules into a packaged, shippable unit. Farway operates two finished-product assembly lines using SOP-based production, station self-inspection, QC full inspection, and QA and OBA sampling. Barcode traceability links each finished unit back to its board-level test records, and anti-static packaging and product-protection controls are applied before shipping.
Application fields for the finished product assembly service china offering include industrial equipment, energy systems, medical devices, transportation electronics, communications hardware, and home appliances. By keeping box-build in-house, Farway eliminates the handoff risk that occurs when a separate contract assembler receives boards it did not build and must reverse-engineer the test regime.
Farway reports having served more than 100 industry customers across more than 20 countries and regions. The company organizes its service-area catalog around six application domains, each with distinct regulatory and reliability requirements:
This multi-industry exposure means Farway's engineering team has likely encountered design-for-manufacturing challenges similar to yours, whether that involves impedance-controlled RF sections, high-voltage creepage spacing, or thermally demanding power layouts.
Counterfeit and substituted components are among the most common causes of field failure in outsourced electronics. A turnkey partner's component management process is therefore as important as its soldering capability. Farway states that it works with authorised brand agents and distributors, reviews customer BOMs for sourcing risks before ordering, and applies incoming quality inspection before parts enter the warehouse.
Controlled warehousing practices include ERP-tracked inventory, first-in-first-out rotation, anti-static storage, vacuum packaging for moisture-sensitive devices, and monitored temperature and humidity. These measures prevent the silent degradation that occurs when components sit in uncontrolled conditions between receipt and placement.
When you narrow your list of candidates, request the following before placing a production order:
A manufacturer that provides all six without hesitation has the documentation infrastructure to support a long-term partnership. Farway's structure, combining engineering, BOM, structural, procurement, maintenance, and testing teams under one roof, is designed to answer these questions efficiently.
Whether you are preparing a prototype for design validation or scaling to volume production, working with a manufacturer that controls the full chain from PCB fabrication through finished product assembly reduces coordination overhead and accelerates your path to market. Farway Electronic offers rapid quotation, experienced engineering support, and standardized production backed by ISO 9001, IATF 16949, ISO 13485, and ISO 14001 certifications.
