Introduction
Managing PCB production through multiple vendors often results in delays, miscommunication, and quality issues—especially under tight deadlines. For engineers, startups, and OEMs, a single-source solution can simplify the process and accelerate delivery.
That's where turnkey PCB assembly offers real value. In this article, we'll explore how it works, its key advantages, and when it’s the smartest choice for your project
What is Turnkey PCB Assembly?
Turnkey PCB assembly refers to a full-service electronics manufacturing process in which a single provider handles all stages of printed circuit board production—from sourcing components and fabricating the PCB to assembling, inspecting, and delivering the final product.
There are typically three types of turnkey services:
- Full Turnkey: The supplier manages everything—including procurement of all components and materials.
- Partial Turnkey: The customer provides some parts or PCBs, while the supplier handles the rest.
- Kitted or Consigned: The customer supplies all materials, and the supplier focuses only on assembly.
| Feature | Turnkey | Partial Turnkey |
|---|---|---|
| PCB Fabrication | Provided by supplier | Provided by supplier |
| Component Sourcing | Fully handled by supplier | Partially customer-supplied |
| Assembly Services | Full assembly included | Full assembly included |
| Testing & QC | Included (AOI, X-ray, FCT, etc.) | Optional, depends on arrangement |
| Client Involvement | Minimal (hands-off) | Higher (coordinate parts delivery) |
| Ideal For | Startups, fast prototyping, low ops | Clients with stock/components in hand |
| Lead Time | Faster overall | Slightly delayed (waiting for parts) |
At Fast Turn PCBs, the turnkey process is engineering-driven, with DFM checks, component sourcing from authorized distributors, and assembly of complex boards—including 01005, BGA, and QFN. In-house SMT, through-hole, and mixed-tech capabilities ensure fast, consistent delivery from prototype to production.
Key Benefits of Turnkey Services
1. Faster Time-to-Market
At Fast Turn PCBs, prototype assembly can be completed in as little as 3–7 working days, and in-stock component assemblies can be delivered within 72 hours.
2. Simplified Supply Chain Management
Turnkey services eliminate the need to coordinate among PCB manufacturers, component distributors, and assembly houses. You simply submit your files—such as the Gerber files and bill of materials (BOM)—once.
3. Improved Quality and Consistency
A single provider oversees the entire process, ensuring consistent quality through AOI, X-ray, and functional testing in accordance with IPC Class 2 or 3 standards.
4. Reliable Component Sourcing
Turnkey providers typically source components from authorized distributors, ensuring traceability, authenticity, and compliance with industry standards.
5. Support for Complex and High-Precision Builds
Modern turnkey assembly supports fine-pitch components (e.g., 01005, BGA, QFN, LGA) and various board types, including rigid, flex, and rigid-flex PCBs.
When Should You Choose Turnkey Assembly?
Turnkey PCB Assembly is ideal for projects that require fast turnaround, limited internal resources, or simplified vendor management. It’s beneficial for:
- Prototyping and low-volume production
- Startups and small teams lacking supply chain experience
- Projects with tight deadlines or frequent design changes
However, if you already have trusted suppliers or prefer to manage component sourcing directly, a partial turnkey or consigned model may be more suitable.
How the Turnkey Process Works
- Submit Design Files
Provide Gerber files and a bill of materials (BOM).
- Engineering Review
The manufacturer checks your design for manufacturability (DFM) and confirms BOM availability.
- PCB Fabrication & Component Sourcing
PCBs are produced, and components are sourced from authorized suppliers to ensure quality and traceability.
- Assembly & Inspection
Surface-mount and through-hole components are assembled using automated lines. Quality is verified through AOI, X-ray, ICT, and FCT.
- Packaging & Delivery
Completed boards are packed and shipped. Fast Turn offers delivery in as little as 3–7 days for prototypes.
Conclusion
Turnkey PCB assembly consolidates fabrication, sourcing, and assembly into a single service—reducing lead times, improving quality, and minimizing coordination efforts. Whether you require full or partial turnkey support, this approach offers the flexibility and efficiency needed for rapid prototyping and small- to mid-scale production.
