Turnkey assembly refers to a comprehensive approach to manufacturing and assembly, where a single service provider takes responsibility for the entire project from start to finish. The provider manages the entire process, from design and engineering to procurement, assembly, testing, and delivery of the final product.

Turnkey assembly providers specialize in handling complex manufacturing projects, where the products require specialized knowledge, equipment, and processes. They have the expertise and resources to manage the entire project, which can help businesses streamline their operations and reduce costs.

The term “turnkey” refers to a project or product that is ready for immediate use or occupancy upon delivery. In turnkey assembly, the provider delivers a fully assembled and tested product that is ready for use by the customer. The provider takes care of all the details, from sourcing the raw materials to managing the supply chain and ensuring quality control.

Turnkey assembly can be used in a variety of industries, including aerospace, automotive, electronics, and medical devices. It can help businesses reduce their time-to-market, improve product quality, and reduce costs by eliminating the need for multiple vendors and streamlining the manufacturing process.


  1. Turnkey PCB assembly comes in two varieties: partial and full. Partial turnkey services means that customers can provide us with some components, then we make assembly. in which only part of the assembly process is outsourced. For Turnkey assembly services, we can source all components for customers to save them time and energy. All you have to do is provide: A bill of materials/Gerber Files/Product dimensions/Packaging and shipping information and so on.
  2. For those companies who have already got a majority of the necessary parts on hand, partial turnkey services can expedite the manufacturing process and save money. However, if you don’t have parts, and are not sure where to order the right ones or don’t know which components are right for your circuit board design, full turnkey service is the more appropriate option.


Turnkey assembly can provide several benefits to businesses and manufacturers. Here are some of the common benefits of turnkey assembly:

  • Time-saving: Turnkey assembly can save time as it involves a single provider handling the entire project, from design to production, assembly, and testing. This eliminates the need for multiple vendors, reducing the time required to coordinate with several suppliers.
  • Cost-effective: Turnkey assembly can be more cost-effective as it minimizes the need for multiple vendors and reduces the overall project management costs. It can also help in reducing the inventory costs and lead times, which can have a positive impact on the bottom line.
  • Expertise: Turnkey assembly providers have expertise in handling a wide range of projects and can provide solutions that are tailored to specific needs. They have the necessary equipment, processes, and experience to handle complex projects, which can improve the quality of the final product.
  • Quality control: Turnkey assembly providers have strict quality control measures in place to ensure that the final product meets the required standards. This can help in reducing the chances of defects and errors, which can lead to costly reworks and delays.
  • Single point of contact: Turnkey assembly providers act as a single point of contact, making it easier for businesses to manage their projects. This can help in reducing the communication overhead and ensuring that the project is completed on time and within budget.


Turnkey assembly involves several components or stages that are managed by the service provider. Here are the common components of turnkey assembly:

Design and Engineering:

Turnkey assembly providers have a team of designers and engineers who work closely with the client to develop the product design. They use computer-aided design (CAD) software to create 3D models of the product and ensure that it meets the client’s requirements.


Once the design is finalized, the turnkey assembly provider procures the necessary raw materials and components required for the project. They have established relationships with suppliers and manufacturers, which enables them to source high-quality materials at competitive prices.


The turnkey assembly provider manages the manufacturing process, which includes fabrication, machining, and assembly of the product. They use specialized equipment and processes to manufacture the product efficiently and ensure that it meets the required quality standards.


Turnkey assembly providers conduct rigorous testing of the product to ensure that it meets the required specifications and quality standards. They use various testing methods and equipment to verify the product’s functionality, performance, and durability.

Shipping and Delivery:

Once the product is manufactured and tested, the turnkey assembly provider manages the shipping and delivery of the product to the client’s location. They ensure that the product is packed securely and delivered on time.

Installation and Commissioning: 

Depending on the product, the turnkey assembly provider may also provide installation and commissioning services. This involves installing the product at the client’s location and ensuring that it is functioning correctly.

Quality control in turnkey assembly

Quality control is a critical aspect of turnkey assembly to ensure that the final product meets the required standards and specifications. Here are some common quality control measures that are used in turnkey assembly:

  • Inspection of Incoming Materials: The quality control process begins with the inspection of all incoming materials to ensure that they meet the required specifications. Any non-conforming materials are rejected and returned to the supplier.
  • Testing of Components: During the assembly process, each component is tested to ensure that it meets the required standards. This includes electrical and mechanical testing, as well as functional testing to ensure that the component works as intended.
  • In-process Inspection: In-process inspection is carried out at various stages of the assembly process to ensure that the product is being assembled correctly. This includes checking the assembly for proper alignment, fit, and finish.
  • Final Inspection: Once the product is fully assembled, a final inspection is carried out to ensure that it meets the required standards. This includes functional testing, as well as visual inspection for any defects or cosmetic issues.
  • Documentation and Traceability: All quality control procedures and test results are documented to ensure traceability and accountability. This includes recording the results of incoming material inspections, component testing, in-process inspections, and final inspections.

Overall, quality control in turnkey assembly is essential to ensure that the final product meets the required standards and specifications, and that it functions as intended.


  • Cost Reduction

With a turnkey contract, there is no extra cost to deliver freight to an assembly workshop. That means it will help you save a lot of cost. Fastlink Electronics also have good working relationships with component manufacturers and can almost always get a better price for parts than small or medium businesses.

  • Quality guaranteed

The advantage of China turnkey PCB assembly is that we have the ability to spot potential issues before production.  Before assembly begins, Fastlink will check to be sure specifications match the application and make sure there are no any errors that may be present. Should any errors be found, you have the opportunity to correct the design and avoid being saddled with thousands of unsuitable circuit boards.

  • Streamlined Management

Dealing with multiple vendors can be stressful and a time drain, especially on small businesses with fewer human resources to go around. With Fastlink Electronics turnkey manufacturing solutions, you stand a far less chance of experiencing a miscommunication because you’re managing multiple channels of interaction. These potential miscommunications can happen between you and suppliers, and it will waste your time and money.
