Automotive sensor market new spring, ceramic substrate to deal with

As for the future development trend of the auto industry, it is a common consensus of all walks of life to become intelligent. As a result, the development enthusiasm of smart cars has increased, attracting a large number of companies and capital participation, and the speed of popularization has continued to accelerate. Driven by smart cars, the automotive sensor market ushered in new opportunities for development.

As the information source of the automotive electronic control system, automotive sensors are the key components of the automotive electronic control system, and they are also one of the core contents of the automotive electronics technology research. Automotive sensors perform real-time, accurate measurement and control of various information such as temperature, pressure, position, rotational speed, acceleration, and vibration. The key to measuring the level of modern limousine control systems is the number and level of sensors. At present, about a hundred sensors are installed on a domestic ordinary family car, and there are as many as 200 sensors on luxury cars.

The engine sensors are the core of the entire vehicle sensor. Using them can improve engine power, reduce fuel consumption, reduce exhaust gas, and reflect faults. Because they work in harsh environments such as engine vibration, gasoline steam, sludge, and splash, they are The technical indicators of harsh environment resistance are higher than those of general sensors.

Chassis control sensors are sensors that are distributed in the transmission control system, suspension control system, power steering system, and anti-lock braking system. They function differently in different systems, but the working principle is the same as that in the engine.

The main purpose of the body control sensor is to improve the safety, reliability, comfort, etc. of the car. The technical requirements for the harsh environment are not as stringent as those of the sensors used in the engine and chassis. The sensors for general industrial use can be applied with a slight improvement. There are several kinds of temperature sensors, air flow sensors, sunshine sensors, etc. used in automatic air conditioning systems, vehicle speed sensors in brake door lock systems, acceleration sensors in airbag systems, light sensors for automatic brightness control, and dead angle alarm systems. Ultrasonic sensors, image sensors, etc.

Smart cars are not the same, and there are many sensors that assist driving, such as the most important infrared radar sensors. In the previous ordinary cars, the sensors used for the stability of the substrate are ceramic substrates, then the ceramic substrate in the new era of smart cars there is so popular it?

Smart cars have made many improvements on the basis of the original, and have not reduced the number of sensors. The added sensors are basically used to detect road conditions and assist driving. Believe that manufacturers do not dare to reduce the requirements for cost, ceramic substrates must be its first choice.

Domestic sensor manufacturers imported large-scale imported ceramic substrates before the appearance of Sridong. Until the appearance of Sliton broke the embarrassing situation of domestic sensors, the imported ceramic substrates were on average about 40% higher than domestic production costs. As a result, domestically produced sensors are not competitive globally. Sri Thongtong discovered this phenomenon, combining state-level laboratories and research institutes of major universities to create a phenomenon-level product. Ceramic substrates made using laser technology are completely different from the previous sintering process and can be used to the maximum extent. The function of the ceramic substrate has a milestone significance for the ceramic substrate industry in China as a whole, which is also one of the reasons for the breakthrough of the sensor in China.

With the rapid development of the Internet of Things, there will be more and more applications of sensors. Slit will lead the domestic ceramic substrate manufacturers, increase production R & D efforts, and strive to contribute to China's production of world-class electronic products.
