The standard laminates, silkscreen, and solder resist method generates the best quality board. Precise pick and place which is an automated machine make the component placement. Besides, the fine reflow ovens archive the solder joints on each of the tiny pin parts.

Early Problem Detection

During the initial project development stage, the turnkey assembly includes design reviews, which allow for identifying possible errors and correcting them. Faults at later stages take extra cost and time. 

Quick lead time

Production time decreases significantly in the turnkey assembly since it uses multiple component sources. In this assembly process, time saves as the manufacturer handles the entire process of PCB assembly. 

Diligent Management

Since, in turnkey assembly, the service provider is the only one who checks all the project updates. It takes on the responsibilities like communicating with the vendors, monitoring the testing line, tracking the assembly progress, and all. This helps in avoiding confusion with different vendors, improves the efficiency of the project, and thus saves time.

Cost Efficient

Cost calculation and analysis is the major factor in any startup. Besides, cost estimation for the manufacturer can help them develop a strong strategic plan for product development. The online quote provides all the details of the complete production of PCB manufacturing. Since the service provider handles all the inventory, thus the price gets lower when they order the component in bulk order. Thus, the price for turnkey PCB assembly decreases. 

Customized Services

The turnkey PCB service provider offers customized assembly service along with various other services like debus, test, packing, and deploying to the customers, etc. They provide the complete package based on the customer's requirements. Thus, you can achieve all the ready-to-use products through this turnkey assembly service provider. 

Type of Turnkey PCB Assembly

Box Build Turnkey PCB Assembly

Manufacturers can perform additional services such as box build assembly and mechanical system integration during box build assembly, which is also known as mechanical system integration. Apart from the actual fabrication of PCBs, the process includes all other necessary tasks. Box build distinguishes PCB assembly from the final delivery.

All the inspections and tests leverage results from the box-build PCB assemblies. Designers should make sure that the PCB-making process is fine and is aligning with the desired specifications.

PCB assembly's built-in boxes involve numerous processes, including but not limited to:

• System configuration`
• Design and Installation of sub-assembly of components.
• Software loading
• Labeling of the final product
• Help in installing wires and cable
• Help in the packaging of assembled circuit boards into enclosures

Full Turnkey PCB Assembly

PCBs manufactured by a turnkey supplier include all the electronic components required for the manufacture of the PCBs. A turnkey PCB assembly involves the procurement of all electronic components through the final assembly of the product. The manufacturer does not provide value-added services like the box build but does provide value-added services to customers. Therefore, designers who don't have time to assemble PCBs will benefit from this turnkey solution.

Partial Turnkey PCB Assembly

Partially turnkey PCB assembly involves the designer supplying the components, and board to the PCB manufacturers. It may be transformers, resistors, capacitors, or another type of circuit board component. Designers with a large inventory of electronic parts will benefit from this type. If not, the PCB assembly manufacturer would face delays in sourcing parts.

Advantages of Turnkey PCB Assembly

• Limited production channels

Working with one company relieves your engineer of the burden of managing multiple contracts. Keeping in touch with multiple people and organizations (especially those overseas) can be stressful, but this software eliminates some of the stress. Additionally, it minimizes the likelihood of software and manufacturing equipment incompatibilities.

• Sourcing components is much simpler

For a single designer, the sourcing process is time-consuming. There is a high chance of compatibility issues and errors. In case you order the wrong components or parts, you won't have any idea about the problem until you face it in prototyping. Turnkey PCB manufacturers thus can help with this problem as it has a direct and stable relationship with the manufacturers and all the team guarantees to make a quality product with no errors.

• Less transportation time

Usually, time is required for rearranging and managing the product from one facility to another. Thus, services need to gather for a strong turnaround.

• Cost Savings

Cost saving is one of the major advantages of turnkey PCB assembly. The assemblies provide various ways of reducing the cost of manufacturing. It doesn't take the extra cost of delivering the components to the assembly house. They have a direct relationship with manufacturers. Thus, there is a signification reduction in the cost of components. You can achieve a good quality board without having any trouble. It is possible to reduce manufacturing costs by using turnkey PCB assembly companies that can prepare the PCB with all its components.

• Fewer Errors

The more people the more the problem with communication and compatibility. Using multiple services for PCB assembly results in communication problems because of time and language barriers. This will cause a problem with the product.

Thus, with turnkey PCB assembly, the team can go through various steps and processes in a well-established manner. They know how to work with various departments and what is required to share for this process.

Disadvantage of Turnkey PCB Assembly

Although the turnkey PCB assembly is good in many factors, it also has some practical problems. Sometimes you choose to use the small turn-time PCB manufacturer, you may end up with low-quality products. This could also result in a lack of financial support for component management services. Sometimes operational problems can also affect the project. Some of them include legal trouble, rogue employees, and natural disaster issues.

Difference Between Full Turnkey and Partial Turnkey PCB Assembly

Turnkey PCB assemblies have two types: partial and full.

A partial turnkey service involves outsourcing only part of an assembly process, which is a form of consignment manufacturing. Part of the supply chain is under the responsibility of the technology developer in a partial turnkey project. Assemblers receive materials from the tech developer, which are sorted and packaged before delivery.

Partially, turnkey services can save businesses money and speed up the manufacturing process when they already have most of the necessary parts on hand. The partial option is the best choice in case you have the parts and components and want to save money and time. Full turnkey service is more appropriate if you don't have components, aren't sure how to order them, or aren't sure what components suit your circuit board design.

They analyze your assembly service provider and provide you with the complete circuit board. They also source all the circuits and parts. But you need to provide them with the BoM(Bill of Materials), Product dimensions, Gerber files, and information regarding packaging and shipping.

What is the Turnkey PCB Assembly Process?

Step 1: Prototyping

In turnkey PCB manufacturers, sophisticated software platforms allow prototyping and small quantity orders to be integrated into larger ones in a cost-effective and timely manner. Uploaded design BoM and documents can receive an instant quote through an online portal; prototype delivery can happen in less time. 

Step 2: PCB Manufacturing

Traditionally, the quantity was a factor when determining cost in the production and manufacturing stage of the design process, but now, companies that accept Gerber files can provide a reasonable quote regardless of order size.

Customers can now calculate the cost per PCB manufactured through online pricing tools offered by electronic assembly providers. It is also possible for designers to track and report on the process of assembling circuit boards.

Step 3: Electronics Device Assembly

The turnkey PCB manufacturing approach uses the service provider for both device manufacturing and PCB assembly. All the process takes place in the same place and this reduces the risk of mishaps and shipping delays. The team can manage all of the production processes while on the other hand, the communication issue also gets solved or crossed out.

Step 4: Inventory Storage and Management

With the completion of PCB assembly, the PCB manufacturing partner can rent and manage space and inventory before shipping your product.

Step 5: System Integration

System integration is the last stage of the PCB assembly process. When a PCB manufacturer knows if an order has been placed, they can satisfy customers' needs. The software of PCB manufacturers integrates ERP systems via APIs, as in banking systems.
