          PCB application in automobile:


          ? surrounding monitor: newer vehicle models are usually designed with a large number of safety systems to help the driver monitor the blind spot and judge the distance more accurately. Many cars are now equipped with perimeter monitoring systems that use radar or cameras to measure distances and remind drivers of close objects. These systems req uire high-quality PCBs to work properly.

          ? control system: vehicle control system, including engine management system, fuel regulator and power supply, and electronic products that use PCB based monitoring and management resources. Some control systems even drive the car for the driver in some cases. For example, some cars on the market now provide automatic parallel parking.

          ? navigation equipment: the existing navigation equipment is very common in modern vehicles. GPS computer is used to help the driver find the path in unfamiliar areas or determine the fastest route to the destination.

          ? audio and video equipment: many cars on the market today have advanced instrument panels that connect the vehicle to the radio or the passenger' s telephone or music equipment. In addition, many family vehicles use passenger movie screens to occupy passengers during long-distance cycling. All these devices are controlled using PCB based electronic devices.

          In any of these Automotive PCB Applications, specific design issues must be considered. For example, the high vibration environment of an automobile may impose a large amount of strain on a standard rigid pcb. Therefore, many automotive electronics manufacturers do not use rigid pcb, but use flexible PCB. In addition to being small and lightweight, it also has stronger vibration resistance. Therefore, the challenge is to manufacture enough high-frequency, flexible PCBs to meet the needs of the large automobile industry.
