Design of Repairable EMI/Moisture Sealing Techniques for Electronic Equipment

在实际环境下,由导电衬垫实现电磁屏蔽的电子设备,因电化学腐蚀频仍发生,因而环境适应性差,是亟待解决的工程技术难题。文中以材料腐蚀学和防护工程学为基础,应用既能实现水汽密封,又能对电磁泄漏发射能量起衰减作用的"密封屏蔽衬垫"实现电子设备可维修水汽密封与电磁屏蔽复合防护设计,满足了电子设备抗恶劣气候环境和电磁环境的防护性、可靠性、维修性、实装性和低成本等综合技战术要求。

In the realistic environment,the frequent occurrence of electrochemical corrosion in electronic equip-ment due to the use of conductive gaskets has led to the poor environmental adaptability,which is an urgent problem to solve.On the basis of the theory of the material corrosion and protection engineering,the application of seal-shield gasket in electronic equipment can seal moisture and reduce the emission energy of electromagnetic leakage.Thus the compound repairable protection design of moisture sealing and electromagnetic shielding can be achieved.And its advantages can meet the requirements of technology and tactics in adverse climate and electromagnetic environment such as protection,reliability,maintenance,economics,practicability etc.
