机载电子设备三防设计应用研究

Research on the Three-proof Design and Application of Airborne Electronic Equipment

对电子设备的三防设计进行系统性阐述,从原材料的选型控制、机箱结构设计、密封设计、异种金属搭接设计和表面涂镀层设计等方面进行分类讨论,以提高电子设备整体的耐三防性能,并对电子设备三防试验注意事项进行了初步总结,相关经验可供同类设备的三防设计及环境试验验证借鉴和参考。

This paper systematically expounds the three-proofing design of electronic equipment, and the classified discussion is carried out from the aspects of selection control of raw materials, chassis structure design, seal design, dissimilar metal overlapping design and surface coating design, etc., in order to improve the three-proofing performance of electronic equipment, and preliminarily summarizes the matters needing attention in the three-proofing test of electronic equipment. And the relevant experience can be used for the verification and reference of the threeproof design and the environmental test for the similar equipment.
