Laminated structure: A typical 4-layer PCB stack structure includes a top signal layer, an inner layer 1, an inner layer 2, and a bottom signal layer. This structure provides more flexibility and complexity in circuit design.
Conductive channel: Through the hole to connect different layers of the circuit to achieve signal transmission and component interconnection.
Material selection: Glass fiber or other insulating materials are usually used as the substrate, and the surface is covered with copper foil for wiring.
Signal transmission: The main function of the 4-layer PCB is to act as a medium for signal transmission between electronic components, and connect the various components through wiring to achieve the function of the circuit.
Power distribution: The inner layer can be used as a power layer (VCC) to provide a stable power supply to the circuit.
Ground protection: The inner layer can also act as a ground layer (GND), providing ground protection for the circuit, stabilizing the signal and preventing interference.
