PCB Technical - Development prospects of automotive electronics PCBA

In today's world development trend, the construction of ecological civilization and environmental protection are becoming more and more urgent, because the quality of the environment is directly related to the reproduction of human beings. This is a livelihood project that benefits future generations. In response to environmental protection measures, autonomous driving and new energy vehicles have become popular. Domestic and foreign companies in this area include Tesla, BYD, and NIO, which directly drive the growth of orders for automotive electronics PCBA manufacturers. At the same time, due to the extremely high demand for stability in automotive electronic PCBA processing, the entry barrier for automotive electronic PCBA processing is high, and at the same time, its profit margin is considerable. About the development prospects of automotive electronics PCBA processing.

(1) Autonomous driving and new energy vehicles promote a substantial increase in the use of automotive PCB circuit boards

With the gradual transition from traditional vehicles to autonomous vehicles and the promotion of new energy vehicles supported by national policies, in order to adapt to the application of new technologies, the demand for automotive high-end electronic control panels continues to increase, and the use of high-end automotive PCB circuit boards is increasing. The more extensive. It is expected that with the maturity and popularization of technology in the future, the level of automotive intelligence will rise to a new level.

(2) Millimeter-wave radar has spawned huge demand for automotive high-frequency PCB circuit boards

At present, automotive millimeter-wave radars are undergoing rapid development. It is expected that the average number of millimeter-wave radars used in a single vehicle will continue to grow in the future, and the demand for automotive radar PCB circuit boards will also grow rapidly. In addition, radar high-frequency circuits have higher requirements for PCB circuit boards and manufacturing processes. Therefore, the automotive radar PCB circuit board will bring higher added value to the PCBA processing industry.

(3) New energy vehicle power battery BMS technology upgrade potential is great

The battery management system (BATTERY MANAGEMENT SYSTEM), the battery management system (BMS) is the link between the battery and the user. The main object is the secondary battery, mainly to improve the utilization of the battery and prevent the battery from overcharging and overdischarging. As one of the hardware foundations of BMS, PCB circuit board components will certainly benefit from its industry development. At this stage, the use area of PCB circuit boards for a single vehicle of luxury cars is about 2-3 square meters. We conservatively assume that the use area of PCB for a single vehicle of new energy vehicles is 2 square meters, and the calculation is 2,000 yuan per square meter. In 2020, the global new energy vehicles The PCB circuit board market has also reached 16.4 billion*.

(4) High barriers to entry for automotive PCB circuit board processing

PCBA processing* manufacturers have a huge first-mover advantage. Due to the special working environment, safety and high current requirements of the car, they have very strict requirements on the reliability and environmental adaptability of the PCB circuit board, which indirectly promotes the development of PCBA processing. High threshold. According to industry sources, zero defect rate is the basic requirement of international manufacturers for PCBA suppliers, and it also determines whether they can enter the automotive PCB processing field. Due to the high barriers to entry for automotive PCBs, car manufacturers generally do not randomly replace certified suppliers in cooperation. Therefore, once PCBA processing manufacturers can successfully enter the supply chain of major international factories, they will not only bring long-term stable orders to the company, but also bring relatively ample room for growth for the company's operations due to the high threshold of the industry. Therefore, the first-mover advantage of *enterprises is very obvious.
