Choosing the Best Turnkey PCB Assembly Factory for your PCB Project

When startups or small businesses encounter difficulties with PCB manufacturing, such as managing a large inventory or a group of experts who will create PCB components, the Turnkey PCB electronics assembly solution offers a reliable and affordable way to create and test printed circuit boards. This denotes the centralization of the entire PCB assembly project workflow.

Due to the high rewards that turnkey PCB assembly service can ensure. Additionally, it will help your business navigate the challenging process of establishing an entire assembly plant. Because of this, this guide will address all of your inquiries regarding turnkey PCB assembly service.

What Does Turnkey PCB Assembly Mean?

The most creative small businesses and startups frequently discover that, when it comes to assembling those printed circuit boards (PCBs), they encounter some difficulties, such as the requirement to maintain a sizable inventory and have an in-house team to create it.

With the shortest lead times possible, turnkey PCB assembly factory is an electronic assembly solution company that provides effective and economical ways to build and test circuit boards for new products. In this manual, we’ll explain what turnkey PCB assembly solutions are and what advantages they offer.

Any good or service that is delivered to the customer prepared for use is referred to as a “turnkey” project. Turnkey assembly is a PCB assembly service where your supplier manages every aspect of the PCB project on your behalf. The supplier buys the PCB’s parts and pieces and assembles it.

Typically, turnkey PCB assembly factories use robust machinery and cloud-based software to assemble circuit boards more quickly and in larger quantities than small and medium businesses can handle on their own.

There are two types of turnkey PCB assembly: partial and full. Consignment manufacturing is a type of service known as partial turnkey, where only a portion of the assembly process is outsourced. The technology developer is still in charge of a portion of the supply chain in a partial turnkey project. This could imply participation in purchasing or assembly.

Your assembly provider will handle every aspect of assembling your circuit boards in full turnkey PCB assembly. They find the components and design the circuit layout.

Stages of a Turnkey PCB Solution

A turnkey PCB assembly requires the following steps to be finished:

Manufacturing of PCBs

The PCB contractor will receive the customer’s PCB Gerber Format at this point. If you don’t have a PCB format, you can still communicate your needs to your service provider using diagrams. The PCB turnkey provider will then produce your own Gerber Format after that.

Trying to find components

All of the components listed on your Bill of Materials will now be purchased by the turnkey PCB service provider (BOM). These include passive, active, as well as custom components.

In order to save time, the process of finding components is taking place concurrently with the turnkey production process. The manufacturer also promises to use tried-and-true components in your printed circuit board project.

Board Assembly

The manufacturer mounts each component on the PCB once the PCB and parts are finished. Surface Mount Technology (SMT) or Through-Hole Technology (THT) are the two options available to the manufacturer. Include the following tools, including a reflow oven and a 3D AOI, in the assembly project.

The manufacturer also makes use of RoHS-certified solder paste, which guarantees a high-quality PCB assembly procedure. Functional testing will be done after assembly is complete to ensure that the PCBs are of high quality.

PCB Testing

Final assembly services are also provided by turnkey PCB assembly companies; all you need to supply is the product packaging and the blueprints. The PCB turnkey supplier will create the product casings, put the pieces together, print the product codes, and then package the finished goods. A manual, inner and outer covers, and the finished assembly will all be included in the packaging, which will adhere to RoHS certification standards.

What Turnkey Assembly Offers

Turnkey PCB assembly’s most obvious advantage is that it spares businesses from having to divert their attention from crucial activities like ongoing innovation in order to spend time working out the assembly details.

There is no need to spend time and effort locating the best component prices, going through a difficult procurement process, and then needing an internal team to expertly assemble them. The following are the main advantages of turnkey assembly:

Cost cutting

You save so much money whenever you use a turnkey contract because it doesn’t cost extra to deliver freight to an assembly workshop. Additionally, turnkey companies enjoy favorable working relationships with component manufacturers and frequently negotiate lower part prices than small and medium-sized companies.

Issue Recognition

A significant benefit of turnkey PCB assembly factory is their ability to identify potential problems before the circuit boards are incorporated into any products, which can save both time and money.

You give the assembler a netlist file as part of the procedure. Before starting assembly, the assembler will make sure that the specifications match the application and find any potential errors. You have the chance to fix the design if any mistakes are discovered, saving yourself from having to produce thousands of circuit boards that aren’t appropriate.

Integrated Management

Dealing with numerous vendors can be time-consuming and stressful, especially for small businesses with scarce human resources. Due to the fact that turnkey manufacturing solutions manage multiple channels of communication, there is a significantly lower chance of a misunderstanding occurring. These potential misunderstandings could occur between you and a vendor or even between vendors, which could cause your timeline to get off track.

Considerations to Make When Selecting a Turnkey PCB Assembly Facility


The first thing you look for when buying anything is quality problems, not to mention things like turnkey PCB assembly. Quality concerns are always taken into account by Turnkey PCB. Every turnkey PCB assembly facility aspires to use printed circuit boards of the highest caliber in its products. High-quality circuit boards will typically have exact tolerances. These tolerances cover the dimensions of all drill holes and vias as well as the thickness, width, and spacing of the copper traces.


All facets of turnkey assembly will be managed by a full turnkey PCB assembly factory. This covers turnkey pcb manufacturing and the purchase of parts and components.

Some professional issues are too complex for all factories to handle. For instance, there will be traces and gap restrictions as the composite board’s layer count rises. Many turnkey pcb assembly plants are unable to resolve this kind of issue. You should also be aware of the types of soldering technology, the dimensions of the circuit boards and the components, and other process capabilities offered by your turnkey assembly manufacturer.

Reaction time

If your business is developing, time is of the utmost importance to you. To achieve the desired design quality, you might need to design and test the prototype more than once. Due to its impact on your final product and your ability to meet delivery deadlines, a quick turnaround time is absolutely essential.


Cost is undoubtedly a significant consideration when selecting a turnkey PCB assembly factory. You must pick a turnkey PCB assembly factory that offers a fair price while also offering quality value for money if you wish to ensure your products can make enough money.


Your turnkey supplier will probably give you a single point of contact through which all transactions will be made, giving you peace of mind and lessening the management burden associated with turnkey PCB assembly.
