Application of Multi-layer Flexible PCB in Aerospace

In the challenging and innovative field of aerospace, multi-layer flexible PCBs play an indispensable and key role. Its unique performance and advantages make it an ideal choice for achieving efficient electronic connections and system integration in aerospace equipment, and it has made outstanding contributions to the development of aerospace technology.

1. Aircraft Electronic Equipment

1) Avionics Systems

In the aircraft’s avionics systems, multi-layer flexible PCBs are widely used in critical subsystems such as communications, navigation, flight control, and cockpit displays. For example, it is used to connect the aircraft's radar system with the signal processing unit to achieve fast transmission and precise processing of radar signals, ensuring that the aircraft can accurately detect the surrounding environment and targets during flight. In the navigation system, flexible PCB connect the satellite navigation receiver to the aircraft's flight management computer, providing the pilot with accurate location information and navigation guidance.

2) Satellite Electronic Equipment

On satellites, multi-layer flexible PCBs also play an important role. The electronic equipment of satellites must possess high reliability, lightweight design, and radiation resistance to withstand the extreme conditions of space. Multi-layer flexible PCBs are used in satellite communication systems, energy management systems, attitude control systems, etc. For example, in satellite communication systems, Multi-layer flexible PCBs connect the antenna and signal processing module, enabling high-speed data transmission between the satellite and ground stations. In energy management systems, they are used to connect solar panels and battery packs to achieve efficient transmission and distribution of electrical energy.

2. Aerospace Sensors

1) Flight Parameter Sensor

Aircraft and spacecraft are equipped with various flight parameter sensors, such as pressure sensors, temperature sensors, and acceleration sensors, which are used to monitor the flight status and environmental parameters of the aircraft in real time. Multi-layer flexible PCBs are used to connect these sensors to the data acquisition and processing systems, ensuring accurate transmission of sensor signal. Its flexibility allows the circuit board to be easily installed near sensors, reducing signal transmission loss and interference. For example, in an aircraft engine, multi-layer flexible PCBs connect the temperature sensors to the engine control system, enabling real-time monitoring of the engine's operating temperature to ensure it runs within a safe temperature range.

2) Environmental Monitoring Sensors

During space exploration missions, spacecraft need to monitor the space environment, including cosmic rays, magnetic fields, micrometeorites, etc. Multi-layer flexible PCBs are used to connect environmental monitoring sensors and scientific instruments on spacecraft to realize the collection and transmission of environmental data. For example, on the Mars rover, multi-layer flexible PCBs connect magnetic field sensors and scientific research equipment, helping scientists understand the magnetic field characteristics and geological environment of Mars.

3. Aerospace Cameras and Imaging Systems

1) Aerial Camera

In the field of aerial photography and reconnaissance, aerial cameras need to have high resolution, fast shooting and data transmission capabilities. Multi-layer flexible PCB is used to connect the camera's imaging sensor, image processing chip and storage device to achieve rapid acquisition, processing and storage of image data. Its good signal transmission performance and anti-interference ability ensure that the image quality is clear and stable. For example, on high-altitude reconnaissance aircraft, multi-layer flexible PCBs connect high-performance aerial cameras and data transmission systems, which can transmit captured ground images back to the ground command center in real time.

2) Space Imaging Systems

In fields such as satellite remote sensing and astronomical observation, aerospace imaging systems have higher requirements for PCBs. Multi-layer flexible PCBs are used to connect imaging equipment such as optical cameras and infrared cameras on satellites with data processing and transmission units. It can work stably under the low temperature and high radiation conditions of the space environment to ensure the normal operation of the imaging system. For example, on earth observation satellites, multi-layer flexible PCBs connect high-resolution optical cameras and data transmission antennas, providing important data support for earth resource monitoring, weather forecasting, etc.
