What is Full Turnkey PCB Assembly

 

As we all know, PCB assembly is a crucial link in the manufacture of electronic devices. All electronic products must go through this link. PCB assembly determines the quality, reliability, and function of electronic devices. The importance of PCB assembly in consumer electronics is shown in the following aspects:

• As a carrier to support electronic components

PCB is a medium that provides a platform. It is a carrier and support for the electrical connection of electronic components. Through PCB, various electronic components attach to realize circuit functions.

• Increase productivity

PCB assembly can be mass production, improving production efficiency. On the market, Most large PCB manufacturers use automated equipment to make PCB assembly faster and more accurate, thereby reducing production costs.

• Optimizing PCB Design

During the PCB assembly process, defects and problems of PCB will fed back to the PCB designer on time. Based on these problems, the designer can adjust or optimize the PCB design solution to improve the manufacturability and functionality of the product.

• Ensure product quality

During the entire PCB assembly process, the equipment will detect whether the quality and performance satisfy the design requirements.

Turnkey PCB assembly has whole turnkey and partial turnkey.
Full turnkey PCB assembly service refers to all processes from procurement to assembly completed by the PCB manufacturer. It does not include boxing, programming, shipping, and other value-added services. Circuit Card Assembly also provides you with value-added services. It is a good choice for customers who are short of time.
Partial turnkey PCB assembly service refers to the customer providing PCB boards and components or some core components and consigned PCB assembly. Partial turnkey PCB assembly is the first choice for customers with inventory.

• Customers provide PCB design and BOM

PCB design is designers designing PCB schematics and circuit diagrams based on the specific functional requirements of the product. After checking that they are correct, give them to our PCB manufacturers for PCB prototypes and high-volume production.
BOM is the list of electronic components and other auxiliary materials. Customers select the corresponding materials based on product performance requirements and provide them to our manufacturers.

• Materials procurement

Material procurement includes the procurement of electronic components and other wire materials. Electronic components mainly include integrated circuits, resistors, capacitors, transistors, etc. Before purchasing, we should analyze the components list provided by the customer to determine the quantity, specifications, type, and quality requirements of the parts.

• PCB Manufacturing and Assembly

PCB manufacturing refers to producing PCB bare boards through PCB proofing, copper printing, etching, lamination, drilling, electroplating, silk screen printing, PCB testing, etc. I won’t describe it in detail here, and we will write an article about the PCB manufacturing process later.
PCB assembly refers to assembling various electronic components’ processes on the bare PCB board. PCBA mainly includes SMT patches, reflow soldering, PCBA testing, and other process flows.

• Final testing and quality assurance

This step ensures that the product meets the quality standards expected by production. Visual inspection is the most common method. Workers will carefully check the appearance of the PCB, including printing quality, solder joints, component location and arrangement, etc. After defects are discovered, the PCB is repaired on time, ensuring high-quality products get to customers.

• Other service

We also provide services that include programming, final enclosure assembly, coating, shipping, etc. At Circuit Card Assembly we can provide customers with a one-stop PCB turnkey solution.
