Partial Consignment Assembly: In this type of consignment assembly, the customer provides some of the required components, such as the PCB or the electronic components, while the assembly company provides the remaining components and the assembly labor and equipment.

Kitted Assembly: In kitted assembly, the customer provides all the required components, but in a kit form. The assembly company provides the labor and equipment required to assemble the board.

Each type of consignment PCB assembly has its own advantages and disadvantages, depending on the customer’s requirements and preferences. It is important to choose the right type of consignment assembly to ensure the best quality, efficiency, and cost-effectiveness.

Difference Between Turnkey PCB Assembly and Consigned PCB Assembly

Once you have completed the design phase of your electronics product, the next step is to create a functioning prototype and bring it to market through volume production. To achieve this, you will need to engage the services of a professional who can handle the printed circuit board (PCB) fabrication and assembly. There are two primary approaches available to you at this stage of the project, each with its own cost/benefit and risk/reward considerations.

You can opt to have your electronic manufacturing completed by either a turnkey provider or a consignment provider. It is essential to carefully evaluate each option to ensure that you select the one that best aligns with your needs and business strategy.

Turnkey Assembly

PCB Turnkey Assembly


The process of manufacturing a printed circuit board (PCB) involves several intricate steps, including circuit board printing and storage, component ordering and warehousing, assembly, and thorough testing to ensure that the final product meets the desired specifications. Transforming a PCB into a successful product requires the installation and shipping of the final product, which can be quite a daunting task.

By leveraging the services of a full turnkey PCB assembly provider, you can outsource all of these complex steps and free up your time to focus on designing innovative products and managing your business operations. This approach allows manufacturing professionals to handle all the aspects outside your area of expertise. With a turnkey manufacturer, you can rely on a single point of contact for any issues or changes that need to be addressed, without the hassle of communicating with multiple vendors to resolve problems.

In addition to simplifying communication, using a turnkey manufacturer can also reduce lead times by eliminating the need for you to procure parts from various suppliers. By sourcing and assembling all necessary components in-house, a turnkey manufacturer can streamline the entire process, resulting in faster production times and a more efficient supply chain.


Collaborating with a turnkey manufacturer involves entrusting them with the responsibility of managing the entire production process of your product. Some enterprises may exhibit apprehension towards relinquishing control over their manufacturing operations to an external party. However, selecting a trustworthy manufacturer guarantees that your product will be handled with utmost professionalism. It is essential to thoroughly evaluate various service providers and be self-assured in opting for a turnkey solution.

Consignment Assembly Services

In consignment assembly, the onus is on you to procure and warehouse all the necessary components for your PCB boards. It is imperative to maintain meticulous inventory records to ensure the smooth assembly of your product. Following this, you must pack and dispatch the components to the assembly company. While this approach provides a certain degree of control, it also places a significant burden on your staff to ensure seamless manufacturing operations. It is crucial to evaluate the impact of this approach on the overall manufacture of your product.


The extent of control that a company seeks to exert over the manufacturing process after the design phase varies depending on their perspective. Nonetheless, if a reputable turnkey provider with a proven track record of delivering quality work is engaged, it is reasonable to trust that they will ensure that the components meet or exceed the specified requirements and tolerances. However, introducing a third-party manufacturer implies relinquishing control over the entire process. For those who prefer to exercise meticulous control over every aspect of the manufacturing process and have the necessary resources to manage the consignment approach, it is a viable option.


Opting for consignment assembly entails assuming a considerable amount of supplementary responsibilities. These include allocating adequate storage space for components, supervising inventory management and procurement of each part, managing multiple supply chains, and sorting, packing, and dispatching the components to the assembly company. This necessitates additional staffing, financial resources, and expertise, which may not be feasible for every business to undertake. Furthermore, any disruption in the supply chain or operational mishaps could potentially arise, necessitating the need for troubleshooting. This means that the consignment approach involves handling several diverse aspects of the process, which requires conscientious problem-solving skills.

How Consignment PCB Assembly Works ?

Consignment PCB assembly is a process where a customer provides all the necessary components and materials to an assembly house, who then assemble and test the printed circuit board (PCB) according to the customer’s specifications. Here are the steps involved in a typical consignment PCB assembly process:
