Product Description

 

China Electronic PCBA Assembly Service

 

 

What is Electronic PCBA?


 

 

Electronic PCBA (Printed Circuit Board Assembly)​​ is the process of mounting and soldering electronic components onto a fabricated PCB (Printed Circuit Board) to create a functional circuit. Unlike ​​PCB fabrication​​ (which produces the bare board), ​​PCBA involves populating the board with components​​ like resistors, capacitors, ICs, and connectors.

 

 

 

♦ ​​Key Stages of PCBA​​

1. Solder Paste Application​​

    • A ​​stencil​​ aligns with the PCB, and solder paste (a mix of tiny solder balls and flux) is applied to pads where components will sit.

​​2. Component Placement (Pick-and-Place)​​

    • ​​Surface Mount Technology (SMT)​​: Automated machines place tiny components (e.g., resistors, ICs) onto the solder paste.
    • ​​Through-Hole Technology (THT)​​: Larger components (e.g., connectors, electrolytic capacitors) are inserted into drilled holes.

​​3. Reflow Soldering (SMT) & Wave Soldering (THT)​​

    • ​​Reflow oven​​: Heats the PCB, melting the solder paste to form permanent connections.
    • ​​Wave soldering​​: Used for THT parts—the PCB passes over a molten solder wave.

​​4. Inspection & Testing​​

    • ​​AOI (Automated Optical Inspection)​​: Checks for missing/misaligned components or soldering defects.
    • ​​ICT (In-Circuit Testing)​​: Verifies electrical functionality.
    • ​​Functional Testing​​: Ensures the assembled PCB works as intended.

​​5. Conformal Coating (Optional)​​

    • A protective layer (e.g., silicone, acrylic) may be applied to prevent moisture, dust, or corrosion.

 

 

 

♦ ​​Types of PCBA Services​​

 

Type Description Best For
​Turnkey PCBA​ Full service—supplier handles PCB fabrication, component sourcing, assembly, and testing. Startups, companies wanting hassle-free production.
​Consigned PCBA​ Customer provides components; assembler only does placement/soldering. Cost-sensitive projects with existing parts inventory.
​Partial Turnkey​ Hybrid approach—some parts supplied by customer, others by the assembler. Customized builds with specialty components.
