The automotive industry is the fourth largest downstream application of the PCB industry. In 2018, about 12% of global PCB demand came from automobiles. According to Prismark statistics, in 2009, the output value of automotive PCB products accounted for 3.8% of the overall PCB output value. By 2018, the proportion has increased significantly to 12.0%, with an output value of approximately US$7.6 billion. Benefiting from the rapid growth of downstream automotive electronics demand, the annual growth rate of automotive electronics PCB is faster than the overall industry level. In 2018, the output value of automotive electronics PCB achieved a year-on-year growth rate of 8.4%, which was higher than the 6% growth of the PCB industry.
2.The application of PCB in automobiles
In terms of PCB consumption for traditional cars, the PCB consumption for ordinary cars is about 1 to 1.5 square meters, and the PCB for luxury cars is about 2.5 to 3 square meters. Because the price per square meter is arount 200 USD, each luxury car PCB is worth about 500 to 800 USD. The main control circuit in the BMS of the new energy vehicle power control system uses about 0.24 square meters of PCB, and the unit price can be as high as 350 USD per square meter. The PCB consumption of the single management unit is 3 to 5 square meters. While the VCU and MCU use relatively less amount of PCB, which is about 0.03 to 0.15 square meters, and the PCB used is ordinary board, the price of which is about 200 usd/square meter.
The average PCB demand is3 to 5 square meters.Concluding other electronic systems, the PCB consumption of the whole car is between 5 to 8 square meters, this means that the PCB demand of a single new energy vehicle is more than 5 times that of ordinary cars. The average price of the power system of a new energy vehicle is about 350 USD per square meter, and other systems are calculated at 200 USD per square meter. The value of a single car PCB is about 1600 to 2000 USD.
According to statistics from the Industry Information Network, the proportions of single and double-sided boards, 4-layer boards, 6-layer boards, and 8-layer boards or more in automotive PCBs are 26.93%, 25.70%, 17.37%, 3.49%, and the total proportion is about 73%. HDI, FPC, and IC boards accounted for 9.56%, 14.57%, and 2.38%respectively, accounting for about 27% in total. It can be seen that multilayer boards are still the main demand for automotive electronics.
PCB accounts for about 2% of the entire electronic assembly cost. Among the electronic components of traditional automobiles, the power system requires the most PCB, with a share of 32%. It mainly includes engine control units, starters, generators, and transmission control. Installation, fuel injection, power steering system, etc. Automotive body electronic system 25%, mainly including automotive lighting, HVAC, power door and seat, TPMS, etc. Safety control system, accounting for about 22%, mainly including ADAS, ABS, safety Airbags, etc.And others also include in-vehicle electronic systems such as display and entertainment.
At present, 70% of automotive innovation comes from automotive electronic products. The growth of the traditional automotive PCB market is mainly driven by factors such as safety systems and vehicle comfort. The development is mainly in the direction of intelligence and electrification. Therefore, the proportion of safety systems and communication entertainment systems is expected Will improve.
3. What parts of the car do we mainly make PCB for?
At present, the circuit boards of automotive electronics account for 30% of our company’s total, which is one of the areas where our company currently accounts for the largest proportion. Our PCBs are mainly used in automotive electronics such as GPS navigation, central control audio and video, automotive electronic instrumentation, car reversing audio and video, new energy batteries and power drive boards, etc.
(Main board of central control equipment, navigation module board, car battery board-copper base, power drive board)

5.Common problems of automotive electronics PCB
The automobile industry is closely related to human safety, so compared to ordinary consumer products, it has higher requirements for product reliability and safety. Therefore, the threshold for entering the automotive supply chain is higher, and higher requirements are placed on PCB manufacturers.
1) IATF16949 (ISO/IATF16949) certification.
You must pass the IATF16949 certification to enter the automotive industry. This process generally takes 1-2 years. IATF16949 is a set of general quality management standards for the automotive industry. It is based on iso9001, but it is more stringent than ISO9001 and has a higher threshold.
In 2008, we obtained ISO TS16949 certification for the first time, and we were the earliest manufacturer of automotive circuit boards in China.
2) Do not change materials, suppliers, and production equipment.
Another feature of automotive electronics PCB is that suppliers are not allowed to change any customer’s design, any materials (even if the materials are better than certified), and any non-certified equipment. Any change needs to be applied for, and the customer’s approval is required to change. If the design changes that affect the quality, the samples need to be re-provided and the customer is required to do certification testing. This process usually takes six months to one year.
We have a professional 4ME and ECN change process, with specific production equipment for car users.
3) The product standard generally implements IPC-3.
The PCB of automotive electronics generally implements the IPC-3 standard, which is more stringent than the IPC-2 requirement. And it is strictly prohibited to affect the functionality of the repair, because this will reduce the reliability of the product. There are also strict regulations for cosmetic repair.
Our company strictly implements all the standards required by IPC.
4) After the PCB is assembled into a semi-finished product, it needs to pass rigorous tests.
These tests include the most basic power-on test, then the aging test, as well as special environmental tests, salt spray tests, and so on. Only PCBs and semi-finished products that pass these tests can be shipped, and the quality is guaranteed to the greatest extent possible.
Our products can pass the above tests, and the product information is trustworthy.
