With the support of national policies, car networking and intelligent driving vehicles are gradually promoted. In addition, major countries in the world have accelerated the process of banning fuel vehicles, and new energy vehicles have become the general trend to replace fuel vehicles. From September 8 to 10, 2017, in the China Automobile Industry Development (TEDA) International Forum held in Tianjin Binhai New Area, China's Ministry of Industry and Information Technology also formulated a timetable to stop the production and sales of traditional energy vehicles. Foreign countries such as the Netherlands and Norway have made it clear that the ban on the sale of traditional energy vehicles will be 2025, and other countries will ban the sale of cars later, between 2030 and 2040. Therefore, the future market of new energy intelligent vehicles is very large, so the demand for PCB is also gradually rising.

A large number of high-voltage and high-power devices included in new energy vehicles, such as IGBT, MOSFET, etc., have high requirements for heat dissipation, making the layout of PCB not too dense, further increasing the amount of PCB in new energy vehicles. For each new energy vehicle, the total PCB board required for the above equipment only reaches about 0.8 square meters. And the power management system (BMS) is the best carrier of intelligent platform, because it is compared with the internal combustion engine, the motor can almost achieve the instantaneous response of the command, more suitable for automatic driving; Moreover, fuel vehicles generally use 12V electrical system, which is difficult to supply more high-power equipment, and the power platform of new energy trams can support more intelligent equipment loads, but at the same time, the heat dissipation requirements are high.

Therefore, aluminum nitride ceramic PCB is a good choice, because it has ultra-high thermal conductivity, can dissipate the high heat in the power system in time, to ensure the normal operation of each high-power load. At the same time, in the car drive module, it is also necessary to anti-seismic and wear-resistant PCB, and the mechanical properties of ceramic materials such as wear-resistant and anti-seismic are excellent, which can ensure its long service life.

According to The Times, the market space of new energy vehicle power modules is expected to increase to 35.11 billion yuan by 2020, ushering in three times the incremental space; By 2025, with the rapid development of new energy vehicles and autonomous driving, it is expected to open 252 billion market space. By then, the demand for aluminum nitride ceramic PCB will also rise, and it is expected that there will be 10 billion market demand.
