Electronics PCB Components Assembly (also called PCBA - Printed Circuit Board Assembly) is the process of mounting and soldering electronic components onto a bare PCB to create a functional circuit board. This process transforms a blank PCB into a working electronic device, such as a smartphone, computer, or IoT gadget.
There are two primary assembly techniques:
Combines both methods for complex designs.
Step | Description |
---|---|
1. Solder Paste Printing | A stencil applies solder paste to PCB pads |
2. Component Placement | Pick-and-place machines position SMD components |
3. Reflow Soldering | Heats PCB to melt solder and form connections |
4. Through-Hole Insertion | THT components are manually/machine-inserted |
5. Wave Soldering (THT) | Solder bonds THT components to the board |
6. Inspection & Testing | AOI (Automated Optical Inspection), X-ray (for BGAs), functional testing |
7. Conformal Coating (Optional) | Protects PCB from moisture, dust, and corrosion |
