New energy vehicle light board refers to the PCB board used for new energy vehicle lights, which is a high-quality, high-precision, high-reliability circuit board. New energy vehicle light boards can meet the electrical connection and mechanical support needs of LED lights and other electronic components, making automotive lamps have better brightness, lower power consumption and longer life. In addition, new energy vehicle light panels can also be customized according to different needs to meet the various requirements of different customers.The automotive industry has the following requirements for printed circuit boards: 1.High reliability: Printed circuit boards are usually used in electronic control systems of automobiles, so they must have high reliability and anti-interference performance. This means that the stability of the PCB line must be ensured in order to ensure the stability and safety of the system. 2.Environmental protection: The automotive industry is very environmentally friendly, and this should also be taken into account in PCB manufacturing and design. Printed circuit boards must comply with ROHS standards, contain no hazardous substances, and minimize waste. 3.Vibration resistance: The automotive industry has high requirements on the vibration resistance of PCBs. The vehicle will constantly bump while driving, and the vibration will affect the electronic components on the PCB. Therefore, the printed circuit board needs to have sufficient anti-vibration strength to ensure stable operation while the vehicle is running. 4.Size and shape: The size and shape of the printed circuit board must be suitable for the design requirements of the car. Due to limited vehicle space, PCBs are often very small in size and require high density and detail to accommodate the vehicle's complex structural requirements. 5.Use in high-temperature and high-humidity environments: The internal environment of the car is complex and often in high-temperature and high-humidity conditions. Printed circuit boards must be able to work stably in such a harsh environment without failure due to changes in temperature or humidity.In the near future, the functions and environmental requirements of automotive electronics will change dramatically. Driven by three major trends: self-driving, connected cars and the growing number of electric vehicles. PCB circuit boards are the key components of these electronic systems. Considering the requirements of automobile safety, PCB circuit boards are not only the connecting parts between the devices. Special attention must be paid to the PCB failure mode in various situations, but also put forward higher requirements on the performance of PCB circuit boards. In a driverless car powered by a few hundred volts, the PCB circuit boards must be kept running reliably. PCBS in cars are affected by the environment during their life, such as temperature, humidity and vibration load. Considering the electrical characteristics of PCB substrates, automotive applications must take into account production tolerances and environmental impacts, such as temperature and humidity, which can affect electrical values. For example, both the relative permittivity and the dielectric loss of the material decrease during thermal aging, but the permittivity increases as the moisture content in the epoxy resin material increases. The functional requirements of new energy vehicles are also varied. The use of PCB circuit boards in electric vehicles may be a cost-effective solution, but the PCB circuit boards must be able to withstand several hundred amperes of current over a million hour lifetime and voltages up to 1000 volts in the automotive environment. On the one hand, the closer to the actuator, such as the power electronics to withstand higher temperatures. On the other hand, electronic devices such as on-board computers are better protected against external stresses and require a longer service life due to charging times and 24-hour service. The automotive industry must ensure high-quality signal integrity and power integrity, and have good electromagnetic compatibility. Special attention needs to be paid to the selection of materials to ensure stability in terms of temperature, humidity and bias in addition to electrical properties. This will lead to future restrictions on material selection and design rules. In order to ensure the necessary electrical properties, PCB manufacturers should be certified for high speed applications.
