From the single words of PCB and PCBA, which is easily to be seen that PCB contains less than PCBA. What do you think? All right. Whatever, let’s see what’s the exactly meaning of PCB and PCBA first. Then the differences between them will be shown simply.
PCB, the full name is printed circuit board, which definitely supports and connects electronic or electrical components. In addition, it can also be used with some conductive tracks, pads and other features etched from the layers of copper laminated onto and/or between sheet layers of a non-conductive substrate.

Here are some different PCBs pictures shown for you.
PCBA, the full name is printed circuit board assembly, which adds all kinds of components during the process of assembly on the basis of PCB. The components includes resistors, capacitors, inductors, IC, diodes, LED, triode,modules, etc.
Here are also some PCBA pictures for your reference.
Now, can you guess what the differences between PCB and PCBA are?
What are the differences between PCB & PCBA?
- Constitute. PCB is only a bare board, while PCBA includes different components on the board already.
- Packing way. PCB is used to be with the vacuum-packaging, while PCBA tends to be packed with anti-static bag and compartmental packaging.
- Cost. For the same circuit board, PCB fabrication is cheaper than PCBA mostly. After all, the cost of purchasing components also need the help of money.
- Function. PCB can’t work without components. PCBA is already possessing partial funtion of the completed products.
- Procedure. PCB is relatively simpler than PCBA, because it need not to be of assembly anymore.
