Cars separate mechanical and electronic equipment. Modern automobile technology combines traditional technology with advanced science and technology, such as manual interior decoration parts and advanced GPS. In modern cars, there are electronic devices with different functions in different locations and different types of car pcbs derive different functions.

According to the substrate information, automotive PCBs can be divided into two categories: inorganic ceramic based PCBs and organic resin based PCBs Ceramic based PCB has high temperature resistance and excellent dimensional stability, so it can be directly applied to high-temperature motor systems. However, it has the characteristics of poor ceramics manufacturability and high cost. At present, with the development of resin substrate materials in terms of heat resistance, resin based PCBs have been widely used in automobiles with different properties and substrate materials at different locations.

Generally speaking, flexible vehicle pcb and rigid vehicle pcb are used in common instruments to indicate vehicle speed, mileage and air conditioning equipment. Double or multilayer PCBs and Flex PCBs are used for audio and video entertainment equipment in cars. For communication and wireless positioning equipment and security control equipment, multi-layer PCB, HDI printed circuit board and Flex PCB are applied For motor control system and power transmission control system of automobile, special plates such as metal substrate and rigid flexible PCB shall be used. For minicar, embedded PCB shall be applied For example, the microprocessor chip is applied in the power controller and directly embedded in the power controller PCB. For another example, PCB of embedded components is also used in navigation equipment and planar imaging equipment of automatic support system
