New energy vehicles

In the field of new energy, IGBT is the core component of the motor drive system for new energy vehicles, accounting for approximately half of the cost of the motor drive system. The motor drive system accounts for 15-20% of the total vehicle cost, which means IGBT accounts for 7-10% of the total vehicle cost. IGBT is the second most expensive component in Alternative fuel vehicle besides batteries, and it also determines the energy efficiency of Alternative fuel vehicle. In addition, the main accessories and peripherals of Alternative fuel vehicle, such as the on-board air conditioning control system and the Charging station of Alternative fuel vehicle, also need to use a large number of IGBT modules.

5G communication

High purity aluminum nitride ceramics have excellent thermal conductivity, heat resistance, insulation, thermal expansion coefficient close to silicon, and excellent plasma resistance. The product has uniform heat distribution and can be applied to heaters for wafer heating, electrostatic suction cups, and other applications. In addition, aluminum nitride precision ceramics often play an irreplaceable role as key equipment components in fields such as aerospace, rail transit, new energy vehicles, high-power LEDs, 5G communication, power transmission, and industrial control.

aerospace

The application of aluminum nitride ceramics in the aerospace field is becoming increasingly widespread. According to reports, NASA is researching the use of aluminum nitride ceramics to manufacture engine blades to improve engine efficiency and performance.

Transportation rail

With the rapid development of electronic technology, the integration level of electronic components continues to improve, leading to a sharp increase in their working energy consumption and heat generation. If the heat dissipation problem cannot be solved, it will lead to the accumulation and rise of internal temperature, leading to the failure and damage of electronic devices. Aluminum nitride ceramic substrates with high thermal conductivity and good insulation can effectively help electronic devices dissipate heat and reduce the loss of electronic devices caused by high temperatures. In addition, aluminum nitride ceramics also have the characteristics of high resistivity, low dielectric constant and dielectric loss, and the thermal expansion coefficient is close to that of single crystal silicon, which can be applied to the packaging of high-frequency, high-power, Very Large Scale Integration.

Solar energy sector

With the maturity of solar panel technology and the country's emphasis on environmental protection, solar panels have developed rapidly in China and are being used in various fields. The solar AC power generation system is composed of solar cell components, charging controller, inverter and battery. The conversion efficiency of Solar inverter directly affects the amount of power generated by the solar power generation system in its life cycle.

LED lighting application field

LED is the fourth revolution in human lighting after fire, incandescent lamps, and fluorescent lamps. Thanks to its various excellent qualities, LED has been favored in many fields. However, there is a major issue with the use of LEDs, which is "heat". Once heat dissipation is not timely, there will be many adverse effects, so the development of aluminum nitride in this area has also been accelerated. For example, in the sterilization and disinfection market, deep ultraviolet LEDs are mainly designed with flip chip and high thermal conductivity aluminum nitride ceramic substrate in order to avoid chip performance degradation or even failure.
