In the electronics manufacturing industry, turnkey PCB assembly is gaining traction for its convenience and efficiency. However, despite its rising popularity among startups and large OEMs alike, many misconceptions still surround this service. In this article, we at GreensTone break down the top 5 myths about turnkey PCB assembly—and set the record straight.
Whether you’re producing EV chargers, smart meters, or medical monitoring systems, knowing the facts could save you time, money, and a lot of headaches.
The Reality:
Many assume that because turnkey services offer an all-in-one solution—including sourcing, assembly, and testing—they must be more expensive than traditional or consigned models. In reality, the opposite is often true.
Turnkey providers like GreensTone leverage bulk purchasing power, long-term supplier relationships, and automated processes to reduce costs. Moreover, with fewer suppliers to manage and reduced lead times, overall project costs can decrease significantly.
Cost Comparison Table:
| Item | Consigned Assembly | Turnkey Assembly |
|---|---|---|
| Component Sourcing | Client responsibility | Handled by provider |
| Lead Time | Longer (multiple sources) | Shorter (one-stop) |
| Logistics Cost | Higher | Lower |
| BOM Management | Manual | Centralized |
| Total Project Cost | Variable | More predictable |
The Reality:
This myth arises from the assumption that in a turnkey model, the manufacturer chooses cheaper or lower-quality components without client input. In truth, reputable providers like GreensTone work closely with clients during the BOM (Bill of Materials) approval process.
At GreensTone, we:
Offer component sourcing based on customer preferences.
Support RoHS, UL, and other certification requirements.
Always seek approval for alternative parts if any substitutions are necessary.
You’re not handing over control—you’re streamlining collaboration with expert procurement teams.
The Reality:
While turnkey assembly is perfect for large volume production, it's equally beneficial for small and medium-scale runs—especially for startups, R&D teams, and custom product developers.
Turnkey assembly simplifies the journey from prototype to production, helping smaller companies avoid the pitfalls of fragmented sourcing and misaligned schedules. At GreensTone, we offer flexible MOQs and pilot run support tailored to every client’s needs—from 10 boards to 10,000.
Use Cases That Benefit from Turnkey PCB Assembly:
Smart home prototypes like smart plugs or sensors
Medical trial devices
Low-volume industrial tools
Pilot batches for traffic control or automotive modules
The Reality:
On the contrary, turnkey PCB assembly often accelerates your project timeline. Since all aspects—from component procurement to testing—are handled under one roof, there’s no need to coordinate multiple vendors or shipping routes.
GreensTone’s in-house SMT/THM assembly lines are designed for speed and accuracy. With our integrated testing and molding services, many customers in the medical, security, and renewable energy sectors experience faster time-to-market and improved reliability.
The Reality:
Some engineers worry that “standardized” turnkey services will limit their product customization. But the best turnkey providers are also the most flexible.
At GreensTone, we offer:
Custom PCB stack-up
Tailored firmware loading and functional testing
Enclosure molding and final assembly services
Special handling for Bluetooth, RF, and GSM modules
In fact, our turnkey model enhances customization, because we control every stage of the process—ensuring consistency and compliance with your specs.
At GreensTone, we’ve helped hundreds of companies—from consumer electronics brands to industrial and medical manufacturers—bring their PCBs to life through full-service turnkey assembly. We stand out by offering in-house SMT and through-hole assembly, certified component procurement compliant with RoHS, UL, and IPC standards, and comprehensive testing options including AOI, X-ray, and functional tests. Additionally, we provide mold and enclosure services for final product assembly, and have extensive experience handling communication modules, power systems, security locks, automotive controls, and more.
