The aerospace industry is a high-tech sector that covers two major branches: aviation and aerospace. It has a profound impact on the technological progress, economic development, and national competitiveness of human society. Aviation mainly focuses on flight activities within the atmosphere, including the design, manufacturing, and operation of aircraft such as airplanes and helicopters; And aerospace focuses on exploration and utilization beyond the atmosphere, such as satellites, manned spacecraft, deep space probes, etc. Although both have their own focuses, they play an indispensable role in promoting technological innovation and economic development.
In the aerospace industry, FPC has a wide range of application scenarios. In satellite communication systems, flexible circuit boards are widely used in antennas, signal processing modules, and RF circuits to provide signal transmission and meet wiring requirements with limited weight and volume. In navigation and control systems, it can provide stable electrical performance under extreme conditions, especially suitable for inertial navigation systems (INS) and flight control modules. In addition, in power and energy management systems, flexible circuit boards are used in battery modules, solar cell arrays, and energy management systems to adapt to complex structural designs and withstand extreme temperature differences. In in-flight entertainment systems, flexible circuit boards are widely used in seat screens, power modules, and control interfaces, providing lightweight and compact designs. In aircraft engines, flexible circuit boards can withstand ambient temperatures of up to 200 ℃ or even higher, making them an ideal choice for engine core circuits.
FPC materials also have certain radiation resistance and can be used for a long time in the strong radiation environment of outer space. In addition, flexible circuit boards reduce the use of traditional connectors and solder joints, lowering the risk of failure at connection points. Their flexibility enables them to maintain stable performance under high vibration and impact conditions of spacecraft. Meanwhile, flexible circuit boards can achieve complex wiring and high-density electrical interconnection, making them suitable for miniaturization and modular design requirements.
With the advancement of aerospace technology and the development of new materials, the application of FPC will become more widespread and develop towards multifunctional integration, lightweight, intelligent, recyclable and environmentally friendly materials. These innovations will bring more possibilities and vitality to the aerospace industry, promoting the sustainable development of aerospace technology.
