1. Substrate (Substrate): The substrate is the main body of the PCB and is usually made of insulating materials, such as glass fiber reinforced epoxy resin (FR-4). It provides mechanical strength and support structure while having good insulation properties.
2, wires (Traces): wires are metal tracks on the PCB, used to connect the circuit path between electronic components. They are typically made of copper foil, formed by processes such as etching or additive plating. The width, spacing and level of the wires can be adjusted according to the circuit design requirements.
3, holes (Vias): holes are through holes connecting different PCB levels. Through the holes, pins such as signal, power and ground wires can be led out from one layer of wires and connected to other layers of wires to realize the connection of multi-layer circuits.
4. Pads: Pads are metal areas used to connect electronic component pins. They are usually located on the PCB and are used to solder components to ensure reliable electrical connections.
5. Components (Components): Components are electronic components mounted on the PCB, such as integrated circuits, resistors, capacitors, and connectors. They are laid out on the PCB and connected to the wires and pads of the PCB by soldering or insertion.
