PCB boards mainly include the following types:
1. Fiberglass board (FR-4): This is the most common PCB board, usually composed of fiberglass and epoxy resin, with good high-temperature resistance and mechanical properties, and can withstand the pressure of multiple layers of PCBA.
2. Metal Core Board (MCB): This type of PCB board has a backboard made of metal, such as aluminum or copper (double-sided copper), used to improve heat dissipation performance, suitable for high-power and LED lighting applications that require heat dissipation.
3. Polyimide Board (PI): This type of PCB board has good dielectric coefficient and thermal performance, and can adapt to high-frequency circuits and high-temperature environments. Therefore, it is widely used in aviation, automotive, medical equipment, military and other fields.
4. Lead Free or Halogen Free PCB Board: This type of PCB board is designed for designers who need to meet the requirements of lead-free and halogen-free circuit applications, which can reduce pollution to the environment and human body.
In addition to the above, there are also some other special purpose PCBs, such as flexible PCBs and high-frequency Teflon PCBs. Different PCB boards have different mechanical and physical properties, and generally need to be selected according to actual application needs.
