FR4 material, as a commonly used printed circuit board (PCB) substrate, is widely used in new energy vehicles. It is mainly used to manufacture various electronic control units, such as motor controllers, battery management systems, in-vehicle infotainment systems, etc. The main advantages of FR4 include high strength, good insulation performance, flame retardancy and relatively low cost.

Specific applications in new energy vehicles:

Motor controller:

The PCB made of FR4 material is responsible for controlling the operation of the motor, including the adjustment of parameters such as current, voltage, and speed.
Battery Management System (BMS):
BMS needs to accurately monitor and control the charging and discharging process of the battery, and PCB made of FR4 material plays a key role in it.

In-vehicle infotainment system:

FR4 material is widely used in various display screens, audio systems, navigation systems, etc., to provide convenience for drivers and passengers.
Advanced Driver Assistance System (ADAS):
FR4 material is used in ADAS to process data from various sensors, such as cameras, radars, etc., to achieve functions such as automatic parking and lane departure warning.

Other electronic control units:

For example, body controllers, lighting control systems, air conditioning controllers, etc., FR4 materials play an important role.

Advantages of FR4 materials:

High strength: Able to withstand vibration and impact during the operation of the car.
Good insulation performance: Ensure the safe operation of the circuit, prevent short circuit and leakage.
Flame retardancy: Can delay combustion and improve safety in the event of a fire.
Relatively low cost: Compared with other high-performance materials, FR4 has a more advantageous price.

It should be noted that:

High-frequency applications:

For applications with high-frequency signals, such as wireless communication modules, FR4 materials may not be the best choice, and other materials with better dielectric properties, such as PTFE or ceramic substrates, need to be considered.

Extreme high temperature:

The performance of FR4 materials may decline in extremely high temperature environments, so the working environment needs to be fully considered during design.

In summary, FR4 materials play an important role in new energy vehicles, providing a reliable substrate for the electronic control system of the vehicle and providing a guarantee for the intelligent and electrified development of the vehicle.
