PCB Assembly Options
Turnkey Assembly
Turnkey assembly refers to a comprehensive service provided by EMS (Electronics Manufacturing Services) providers that cover the entire process of electronic assembly, from procuring components to final assembly and testing. Essentially, customers provide the PCB design files and specifications, and the EMS company takes care of the rest.
At BPUR Technology, we offer a complete range of support and services, starting from circuit design all the way to product delivery. Being a manufacturer with our own manufacturing and assembly workshop, we can cater to most customer requirements, including prototyping, batch production, manufacturing, assembly, procurement, testing, and more.
The turnkey PCB assembly service is ideal for customers who want to outsource the entire assembly process and have a single point of contact for their electronic projects. This allows customers to save time on project management and allocate resources to the final sales process.
Partial Turnkey Assembly
Partial turnkey assembly offers a cost-effective solution for PCB circuit board assembly, where the customer handles certain aspects of the assembly process while the assembly company takes care of the remaining tasks. In certain scenarios, customers have the option to provide specific components such as ICs and main control chips, while the service provider handles the procurement of conventional components like inductors and capacitors.
This assembly option is well-suited for customers who possess specialized or unique components that they prefer to supply, or those who desire greater control over the assembly process. It is also a cost-effective choice for customers aiming to reduce component procurement expenses. However, it is essential to note that this option necessitates the assembly company to possess adequate procurement and management expertise, as well as involve increased coordination. Otherwise, it may potentially impact the overall quality of the project.
Consigned Assembly
Consigned assembly is a PCB assembly service where the customer provides the PCB board and all the necessary electronic components, and the service provider carries out the final assembly and testing. This option can be highly cost-effective for customers, as they can purchase components in larger quantities and take advantage of volume pricing.
However, consigning the assembly process to the customer entails higher risks, primarily related to procurement costs and dealing with multiple service providers. Firstly, it requires electronics manufacturers to possess specific storage management capabilities, a tolerance for component failures, and extensive channels for component procurement. Additionally, most electronics manufacturers do not have in-house PCB manufacturing capabilities, necessitating collaboration with separate PCB manufacturers and PCBA processing plants. This can lead to information gaps, making communication less streamlined compared to point-to-point communication.
Kitted
The customer is responsible for procuring all materials, while BPUR 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 BPUR can provide all the services that these service providers offer.
Bare Board Assembly
This solution assumes that the customer already has an established and reliable PCB manufacturer. The PCB manufacturer is entrusted with manufacturing the bare boards and delivering them to BPUR. Subsequently, we proceed to procure and assemble electronic components in accordance with the customer’s specifications and documentation.
Fully Custom PCBA
This type of service is also known as mixed assembly and offers a fully customizable option for customers. They have the flexibility to combine various solutions mentioned earlier based on their specific requirements. This service approach ensures maximum flexibility to meet individual customer needs and achieve successful electronic assembly processes.

Printed Circuit Assembly Process
Step 1: Applying Solder Paste
Solder paste, a mixture of solder alloy particles and flux, is applied to the surface mount pads on the PCB using a stencil. This step ensures that solder will properly bond the components to the PCB during the reflow soldering process.
Step 2: Component Placement
Surface mount components, such as resistors, capacitors, integrated circuits, and connectors, are accurately placed on the PCB. This can be done manually or with the help of automated component placement machines.
Step 3: Reflow Soldering
The PCB with the components in place is passed through a reflow oven. The oven heats the solder paste, causing it to melt and create strong electrical connections between the component leads and the solder pads on the PCB. Once cooled, the solder solidifies, forming permanent solder joints.
Step 4: Through-Hole Component Insertion
If the PCB includes through-hole components, such as connectors or larger components, these are inserted into pre-drilled holes on the PCB. The leads of the components are then soldered to the PCB using techniques like wave soldering or selective soldering.
Step 5: Inspection and Testing
The assembled PCB undergoes thorough visual inspection, automated optical inspection (AOI), or X-ray inspection to ensure component placement accuracy and solder joint quality. Functional testing may also be performed to verify the proper operation of the assembled circuit.
Step 6: Cleaning and Packaging
Following inspection, the PCB may undergo a thorough cleaning process to remove any residual flux or contaminants, ensuring long-term reliability. Subsequently, the PCB is prepared for shipment through final assembly, which may involve adding mechanical components, enclosures, labeling, and appropriate packaging for safe delivery.
