One of the most common substrate materials is fiberglass reinforced epoxy, also known as FR-4. FR-4 has good mechanical strength and heat resistance and is suitable for most application scenarios. In addition to FR-4, there are other types of substrate materials, such as ceramic substrates and metal substrates, that provide higher performance and stability in specific applications.

Secondly, the conductive paths of the PCB are made of copper. Copper was chosen as the material for the conductive paths because it has good electrical conductivity and mechanical strength, and is relatively easy to process. During the PCB manufacturing process, copper is deposited on the surface of the substrate and chemically etched to form the required conductive pattern.

Finally, the insulating protective layer of the PCB is usually composed of solder film. The solder film covers the surface of the PCB to insulate and protect the conductive path to prevent short circuits and damage to the circuit from the external environment. Solder mask is usually a high temperature resistant polymer material such as polyimide (PI) or polyamide (PA).

In addition to these common materials, modern PCB manufacturing also uses some advanced materials to meet specific design needs. For example, flexible substrates use flexible polyester films as the substrate material, which can be used in applications that require bending or folding. Metal substrates use metal substrates to replace traditional substrate materials, providing better heat dissipation performance and mechanical stability, and are suitable for high-power and high-frequency circuit design.

In summary, PCB material selection is critical to the performance and stability of the circuit.
