There are various types of printed circuit boards (PCBs).
1、 According to the substrate material, PCBs can be divided into the following categories:
1. Paper substrate PCB
Paper substrate is a common type of PCB, whose substrate is made of a mixture of glass fiber cloth and resin, and is covered with a layer of copper foil on the surface. This type of PCB has good insulation and processing performance, and the cost is relatively low.
2. Metal substrate PCB
Metal substrates are mainly composed of metal composite materials, which have good thermal conductivity. It is commonly used in high-power electronic devices to ensure the normal operation of circuits and prevent device overheating.
3. Ceramic substrate PCB
Ceramic substrate is a PCB based on ceramics, which has good insulation performance and thermal stability. It is commonly used in high-temperature, high-frequency electronic devices such as aerospace and communication equipment.

2、 According to the manufacturing process, PCBs can be divided into the following categories:
1. Sinking gold board process PCB is a process of forming a metal deposition layer on the copper surface of a circuit board through chemical or physical methods. The gold plating process can improve the conductivity and reliability of circuit boards.
2. Through hole plating process PCB (PTH) In this process, conductive holes are formed on the circuit board through chemical methods to achieve circuit connections between different layers. This process is suitable for the production of multi-layer boards.

3、 According to the field of use, PCBs can be divided into the following categories:
1. In the field of communication, PCBs are used as circuit boards for communication equipment, such as mobile phones, routers, and other communication devices. They need to meet the requirements of high-speed transmission and stable operation.
2. With the increasing level of automotive electronics, the demand for PCBs in the automotive industry is also growing. They need to meet the requirements of high temperature, vibration resistance, and reliability.
In summary, there are various types of PCBs that can be classified based on substrate materials, manufacturing processes, and application areas. Different types of PCBs have different characteristics and applicable scenarios.
