飞机电子设备应用了大量的微型电路,这些电路大多是由半导体器件构成的,很脆弱,当遭到静电袭击时,可使机件或设备受到破坏。这种储存在物体上的静电电位有时很高,其数量级可从数十伏到数千伏,有的甚至能危及到人的生命。随着航空技术的发展,飞机上的电子产品集成化程度越来越高,电路板上的绝缘层越来越薄,连接导线的宽度和间距也越来越小,因此航空电子产品在维修时的静电防护也显得越发重要。 A large number of microcircuits are used in aircraft electronic equipment. Most of these circuits are made of semiconductor devices and are so fragile that they can damage parts or equipment when struck by static electricity. The electrostatic potential stored on an object is sometimes high, in the order of tens of volts to thousands of volts, and some can even endanger human life. With the development of aviation technology, the degree of integration of electronic products on the aircraft is getting higher and higher, the insulation on the circuit board is getting thinner and the width and spacing of the connecting wires are also getting smaller and smaller. Therefore, when the avionics are in repair The electrostatic protection is also more and more important.
