What is PCB

Update: December 13, 2023 Tags:electronicicpcb

pcb means printed circuit board.

It can be seen everywhere, and it is the support and electrical connection carrier of electronic components in electronic circuits.


How are these components connected? In fact, there may be hundreds of copper wires inside the PCB, and even multiple layers of overlap, and are insulated from each other. The components on the PCB are connected to each other through different layers of wires, which do not interfere with each other and work efficiently.

In fact, PCB has single-sided, double-sided and multi-layer boards. For example, the PCB in mobile phones may reach as thin as 10 layers. How amazing!
