What are the uses of power board PCB?

2022-03-12

The power board PCB is mainly composed of pads, vias, mounting holes, wires, components, connectors, fillers, electrical boundaries, etc. The main functions of each component are as follows:
1. Pad: A metal hole for soldering component pins.
2. Vias: metal holes used to connect component pins between layers.
3. Mounting hole: used to fix the printed circuit board.
4. Conductor: Electrical network copper film used to connect component pins.
5. Connector: a component used for connection between circuit boards.
6. Padding: The copper used in the ground net can reduce impedance.

7. Electrical boundary: used to determine the size of the circuit board. All components on the circuit board cannot exceed this boundary.
