Turnkey PCB assembly refers to a type of electronic assembly service. It provides a cost-effective and efficient means of developing and testing electronic circuit boards for fresh products. Turnkey PCB assembly also has the shortest possible lead times.  The term “Turnkey” denotes a service or product that is ready for deployment by the buyer.

In PCB assembly terms, however, turnkey assembly implies a service that sees the supplier handling everything related to the project on behalf of the consumer. It includes the procurement of components and parts besides assembling the printed circuit board. The process typically utilizes cloud-based software besides powerful machinery to assemble the circuit boards. It accomplishes this efficiently and at higher volumes compared to medium and small businesses.

Benefits Accruing from Turnkey Assembly

An obvious advantage of turnkey printed circuit board assembly entails businesses taking their focus off PCB assembly. Such focus instead gets redirected to other critical processes such as constant innovation. You do not need to spend energy and time finding ideal component costs or going through the frustrating procurement process.  However, the most noteworthy benefits include the following.

Issue Identification

One major cost-saving and time benefit of a turnkey printed circuit board is the capability of spotting potential issues before the board gets deployed for application. A necessary aspect of the procedure entails submitting a netlist to the assembly company. It is upon the assembler to check and ensure the specs match the intended application before assembly. Additionally, they have to spot any present errors. Such errors need to get corrected upon identification, especially on the printed circuit board design. If an error does not get corrected, it can cumulate and ensure you end up with thousands of inapt circuit boards.

Cost Reduction

Most turnkey contracts have no additional costs when it comes to delivering the consignment to the assembly company. Additionally, most assembly partners have established and decent working relationships with most component manufacturers. It helps drive down the cost of sourcing for these electronic parts compared to medium and small businesses.

Streamlined Management

It is always a stressful process when dealing with numerous vendors, especially for small businesses. You spend a lot of time, and you also have to use a limited human resource pool. Therefore, a turnkey PCB assembly solution reduces the possibility of experiencing miscommunication between you and the vendor. It also reduces miscommunications between vendors to avoid derailing your timeline or waste any money.

Most turnkey suppliers will possibly give you one contact point to conduct all business aspects. It helps in keeping you calm (mind-wise) besides lightening the management burden of the PCB assembly.

Instant Quotes

Plenty of the traditional manufacturing approaches are insensitive to time. As a result, designers have to wait for extended weeks to get cost estimates on their PCB assembly orders. But the onset of turnkey assembly services has proved a game-changer. Customers can now know their assembly order costs immediately after uploading their bill of materials (BOM) files on RayMing PCB and Assembly portal or any other turnkey PCB company of their choice.


Any PCB designer will tell you of the expensive and typically slow process of developing the first PCB prototype. Critical factors like PCB components or parts and materials getting out-of-stock can become problematic in hampering your PCB project’s lead times. It also gets complicated further by trying to manage numerous suppliers simultaneously. But turnkey printed circuit board assembly solutions change the game. It allows you to access prototype services at low-cost prices and rapidly from different turnkey prototype PCB companies.

Full Turnkey vs. Partial Turnkey

Turnkey printed circuit board assembly is of two types: full turnkey and partial turnkey services. Full turnkey encompasses the assembly provider carrying out all the work of assembling the printed circuit boards. It involves sourcing the components and developing the PCB order. As an electronics consumer, all you need to do entails providing a BOM (bill of materials), product dimensions, Gerber files, and shipping and packaging information. A full turnkey PCB assembly service represents something akin to investment compared to a partial turnkey service. It also dramatically enhances your PCB acquiring experience, especially when you are still a novice at dealing with electronic circuit boards.

Partial turnkey PCB services, on the other hand, is a consignment manufacturing form that features only a part of the PCB assembly process getting outsourced. For instance, partial turnkey PCB projects feature the tech developer retaining the responsibility for a supply chain segment. It can imply involvement in buying or assembly. In most instances, it features the consignment model having the technology developer taking charge of obtaining, packaging, and sorting materials for eventual delivery to the assembly company.

For those businesses with a bulk of the essential components or parts on hand, it (turnkey services) has the potential of expediting the production process besides saving you money. But in the absence of components or parts and inability to determine with certainty where to source for the right components, full turnkey services might prove more beneficial.

Full Turnkey PCB Assembly

The idea of obtaining a full turnkey service can prove appealing, especially as a small business. In this case, it may often prove that your needs can get better served by box build assembly. Box build assembly refers to a service specializing in performing other essential assembly processes than the PCB assembly itself. It is sometimes referred to as system integration and completes the remaining steps between the printed circuit board assembly and the delivery of the ultimate electronic product.

For instance, the steps covered in the box build assembly can infer a simple placement of the assembled electronic circuit in its enclosure. However, it can also encompass complex processes like connecting the printed circuit board assembly to a user interface. Some of the other significant box build assembly work include aspects like:

  • Design and installation of sub-assembly components
  • Sourcing for and the installation of wiring and cable harnesses
  • Loading the applicable software
  • Packaging all the assembled components or parts in their corresponding custom enclosures
  • Packaging PCBAs and labeling them
  • Configuring systems

Such electromechanical assembly processes need dedicated and experienced staff, sufficient production space, and specialized equipment. Only a few small-scale companies or businesses have that kind of resources available to them. Additionally, a critical service that box build assembly comes with encompasses testing and inspection of market-ready boards. Testing is a component of the QMS (quality management system) registered as ISO 9001. It ensures that the testing process proves as rigorous and recent as possible. Consequently, you should not worry much about potential and expensive electronic product failures besides the consequences of the extension to your timeline (project-wise).
