No new car can function without on-board computers that require complex automotive PCB printed circuit boards to function. More and more car models on the market offer 24-GHz mmWave short-range radar (SRR) systems. In order to really contribute to the transformation of automotive electronic systems, the use of radar systems will greatly enhance the safety performance of automobiles.

New Opportunities for Automotive PCB Suppliers

Historically, the cost of automotive electronics has continued to grow, and the trend will continue. The proportion of automotive electronics in new energy vehicles has reached 65%, which is significantly higher than that of fuel vehicles. The continuous improvement of automotive electronics applications will drive the growth of its basic components - the demand for automotive PCB Suppliers. Automotive PCB Suppliers are used in control systems, audio-visual systems, GPS modules, etc. Under the promotion of the new four modernizations of automobiles in the future, the value of single vehicles is expected to increase significantly, driving the overall automotive PCB Suppliers market to continue to grow.

5G accelerates the penetration of the Internet of Vehicles and further opens up the growth space for automotive PCB Suppliers. According to agency estimates, by 2025, the global automotive PCB Suppliers output value will exceed 100 billion , and the compound growth rate from 2021 to 2025 will be about 15%. Upstream copper-clad laminates for automotive PCB Suppliers account for about 30% of the overall cost. At present, copper prices and epoxy resin prices have stabilized or dropped, which is expected to ease the pressure on PCB manufacturers. Domestic automotive PCB manufacturers have expanded production to cope with future demand increases, and the overall development of the industry is thriving.

Automotive PCB Suppliers Industry Scale

PCB is widely used in automobiles, and automobile is also an important application field of PCB. The PCB acts as a support for electronic components. From the perspective of the PCB industry, automobiles have become the second largest application field of PCBs in 2020, accounting for about 16% of automotive PCB Suppliers.

The automotive PCB Suppliers market will rapidly grow to a scale of 100 billion. With the development of automobiles in the direction of electrification and intelligence, automotive PCB Suppliers will develop rapidly. Affected by the epidemic, global car sales in 2020 will be 78.03 million, a year-on-year decrease of 13%. In 2021, under the background of low car sales base and rising prices of upstream raw materials, the automotive PCB Suppliers market is expected to grow significantly. We predict that the global automotive PCB market will exceed 100 billion yuan in 2023, and the CAGR from 2020 to 2025 is expected to reach 25.7%.

Automotive PCB customers have high certification thresholds and long order cycles. Automobiles also have high requirements for reliability. The certification cycle of automotive PCB boards is generally 2-3 years, and manufacturers generally do not easily change suppliers.

The increase in the degree of automotive electronics has correspondingly driven the demand for automotive PCB Suppliers, and the amount of PCBs used in new energy vehicles is 5-8 times that of traditional vehicles. The electronic difference between hybrid and pure electric vehicles is mainly in the battery. As far as the value of the vehicle is concerned, the incremental demand brought by the two is basically the same, so there is no need to distinguish them. Whether it is pure electric or hybrid, the increase in automotive PCB demand mainly comes from the electronic control system, and a small part comes from electric drives and power batteries. 

In traditional cars, the amount of PCB for each ordinary car is 0.6-1 square meters, and the amount for high-end models is 2-3 square meters. Based on the different design schemes of new energy, the average automotive PCB Suppliers area used by cars is about 5-8 square meters, which is 5-8 times that of traditional cars, and the value increment of a single car for the electronic control system alone exceeds 2,000 RMB.

With the popularization of new energy vehicles, the degree of electrification of electric vehicles is much higher than that of traditional power vehicles, and the rapid penetration of new energy vehicles has improved the overall degree of electrification of the industry. The demand for automotive PCB Suppliers from new energy vehicles also has huge potential. With the support of industrial policies, the domestic new energy vehicle market has maintained rapid growth since 2014. BMS in new energy vehicles is one of the core components, and automotive PCB boards will also benefit from the development of new energy vehicles. As the support of electronic components, automotive PCBs will inevitably benefit from automotive electronics. According to industry data, the amount of PCBs used in new energy vehicles is 5-8 times that of traditional vehicles.

The PCB cost of traditional compact, mid-to-high-end cars, hybrid cars, and pure electric cars accounts for 15%, 20%, 47%, and 65% of the entire vehicle, respectively. Under the background of automobile electrification, it is expected that the electrification rate of automobiles will increase to nearly 50% between 2020 and 2030, much higher than the 4.8pct increase during 2010-2020.

New energy vehicles have a higher degree of electronics. New energy vehicles are represented by electric vehicles. Compared with traditional fuel vehicles, the main difference lies in the four major components, drive motor, speed controller, power battery, and on-board charger. The on-board battery is used as the energy source and the motor is used as the power. The source drives the vehicle, and the standard of the required automotive PCB Suppliers is also higher. Electronic devices account for about 25% of the cost of traditional luxury cars, and 45% to 65% of the cost of new energy vehicles.

New Energy Vehicle BMS

A new growth point for automotive PCBs. Lithium battery is the core energy of new energy vehicles. In order to ensure the safe and reliable operation of the battery, it is necessary to monitor the battery in real time through the battery management system (BMS). BMS is also called the brain of the battery system of the electric vehicle. The system together constitutes the three core technologies of electric vehicles. PCB is the hardware foundation of BMS. A large bus has 12 to 24 automotive PCB boards, and a small car has 8 to 12 automotive PCB boards. The main control circuit consumes about 0.24 square meters, and the single management unit is 2 to 2 3 square meters, automotive PCB will usher in a large volume with the growth of the market size of new energy vehicles.

The heavy volume of millimeter-wave radar will bring huge demand to high frequency automotive PCBs. At present, automotive millimeter-wave radars are developing at a high speed. In the next two years, automotive millimeter-wave radars will be in a period of heavy volume. Generally, cars that support ADAS functions will use at least 4 millimeter-wave radars. The new Audi A4 uses 5 millimeter-wave radars, and the Mercedes-Benz S It is expected that the average number of millimeter-wave radars used in single vehicles will continue to grow in the future, and the demand for automotive PCBs will also grow rapidly.

Millimeter-wave radar products are about to enter the heavy-duty period, and high frequency automotive PCB boards are required to realize the function of the antenna—to maintain sufficient signal strength of the antenna in a small integration space.High frequency automotive PCB with higher specifications for 77Ghz radar will bring huge demand for corresponding high frequency automotive PCB boards when widely used.
