PCB assembly encompasses the process of mounting electronic components onto a bare board through assembly and soldering techniques, resulting in a fully functional PCBA board. The accurate circuit board assembly is crucial to achieving the desired functionality and involves multiple aspects, including precise component placement and accurate soldering. Even a minor error, such as a misplaced resistor or a small cut in the trace, can lead to assembly malfunctions. To ensure the success of your project, it is essential to partner with a reliable PCB assembly service provider like Mero Group.

Printed Circuit Assembly Scheme
The best PCB assembly service manufacturers should possess the capability to offer customized services tailored to the specific requirements of each customer. This is essential because companies of varying sizes, at different stages, and with distinct needs will have unique demands in terms of projects.
Turnkey Scheme
Turnkey refers to a comprehensive service provided by EMS providers that encompasses the entire electronic assembly process, from component procurement to final assembly and testing. In other words, customers provide the PCB design files and specifications, and the EMS company handles the rest.
At Mero Group, we offer a complete range of support and services, from circuit design to product delivery. As a manufacturer with our own manufacturing and assembly workshop, we can meet most customer needs, including prototype to batch, manufacturing to assembly, procurement to testing, and more.
The turnkey PCB assembly service is suitable for customers who wish to outsource the entire assembly process and have a single point of contact for their electronic projects. This enables customers to save time in project management and allocate resources to the final sales process.
Partial Turnkey Scheme
Partial turnkey is a cost-effective solution for PCB circuit board assembly that involves the customer handling some aspects of the assembly process, while the assembly company takes care of the rest. In some cases, customers can provide specific components, such as ICs and main control chips, while the service provider is responsible for purchasing conventional components, such as inductors and capacitors.
Partial turnkey PCB assembly option is suitable for customers who have specialized or unique components they prefer to supply, or who wish to have greater control over the assembly process. It is also cost-effective for customers who want to save on some component procurement costs. However, it is important to note that this option requires the assembly company to have sufficient procurement and management experience, and involves more coordination, otherwise it may impact the overall quality of the project.
Consigned Scheme
The consignment PCB assembly service means that the customer provides the PCB board and all the required electronic components, and the service provider only needs to carry out the final assembly and testing. This option can be the most cost-effective for customers as they can purchase components in larger quantities and benefit from volume pricing.
However, consignment to a client comes with higher risks, reflected in procurement costs and multiple service providers. Firstly, it requires customers to have certain storage management capabilities, risk tolerance for component failures, and extensive component procurement channels. Additionally, most customers do not have PCB manufacturing capabilities, which means that they need to cooperate with PCB manufacturers and PCBA processing plants simultaneously. This can cause information gaps, making communication less convenient than point-to-point communication.
Kitted Scheme
The customer is responsible for procuring all materials, while Mero Group handles the PCB manufacturing and assembly, as well as PCB testing according to customer needs after the production process is completed. Through past service projects, we have found that some of our customers rely on foreign trade service providers in Hong Kong for procurement, although it is an undisputed fact that their services are good. However, this means that our customers have to bear unnecessary costs, because Mero Group can provide all the services that these service providers offer.
Bare Board Assembly
This solution assumes that the customer already has a stable and high-quality PCB manufacturer. The PCB manufacturer is responsible for manufacturing the bare boards and delivering them to Mero Group. We then purchase and assemble electronic components according to the requirements of the customer’s documentation.
Fully Custom PCB Assembly
This type of service can also be referred to as mixed assembly, and it is a fully customizable service option. Customers can combine the different solutions we have mentioned according to their specific needs. This form of service provides maximum flexibility to meet individual customer requirements and achieve successful electronic assembly processes.
PCB Assembly Process
One of the most important factors in the overall efficiency of each PCB assembly project is the client’s understanding of our process. The number of steps involved in the PCB assembly process depends upon the specific nature of the project in question, as illustrated below, and each of these steps is explained briefly in the following sections.
DFM Check
DFM checks our client’s PCB design and looks for issues that may influence the final product negatively, such including missing, redundant or potentially problematic features. And the consistency across different design documents like BoM and Gerbers.
