What is the difference between PCBA and PCB? [Chart Explanation]
PCBA refers to the structure of the whole after soldering electronic components (including SMD chip components and DIP plug-in components) on the basis of the PCB bare board, and the difference between PCBA and PCB can be detailed in the following table
| Contrast | PCBA | PCB |
| Contains electronic components | ✔ | ✖ |
| Electrically connected (with wiring) | ✔ | ✔ |
| The main processes undertaken | PCB manufacturing process + SMT placement + DIP plug-in | Cutting, drilling, exposure and development, etching, copper immersion, electroplating, silk screen printing, surface treatment, etc |
| thickness | PCB boardThickness + component height | PCB board thickness (e.g. 0.2mm ~ 4mm) |
| Ability to write programs | ✔ | ✖ |
| Whether the functions of electronic products can be realized | ✔ | ✖ |
