Application of Electronic Wiring Board in Astronautic Field

Wiring is an important link in the production process of cable harness. The quality of wiring is related to the final compliance and external structure of cable harness. Cables with fewer branches and large dimensional tolerance are generally directly wired manually, while cables with complex structure and high-dimensional accuracy requirements are generally wired by wiring boards. Wiring boards can be divided into traditional templates [Shen and Zhang in Technical requirements for wire binding manufacturing process, No. 200 Factory. Ninth Research Institute of China Aerospace Science and Technology Corporation, pp 4–7, 2014, 1] and modern electronic wiring boards. The traditional pattern wiring method is complicated and time-consuming from the printing of wiring drawings, blueprint, drawing distribution, drawing fixing, and tooling positioning to the start of wiring. The pattern wiring can no longer meet the requirements of mass production and is basically no longer used. Compared with the traditional model wiring process, the electronic wiring board has simpler process and faster wire changing speed, and the electronic wiring board meets the core requirements of Industry 4.0, which realizes synchronization of design and manufacturing, and intelligent and digital production. The electronic wiring board has been widely used in the field of automobiles. At present, it has also been applied to some extent in the astronautic field.
