外壳设计中的腐蚀控制和电导率

[中文适用范围]： 腐蚀控制始终是电子 enclosure 设计者关注的问题。使用 EMI 垫片提供屏蔽通常会产生与理想腐蚀控制相冲突的要求。本 SAE 航空航天推荐做法（ARP）提供了一个兼容性表（见图 1），其目标是列出在腐蚀方面兼容且仍能保持低接触阻抗的金属配对。 [外文原描述]： Corrosion control is always of concern to the designer of electronic enclosures. The use of EMI gaskets to provide shielding often creates requirements that are in conflict with ideal corrosion control. This SAE Aerospace Recommended Practice (ARP) presents a compatibility table (see Figure 1) which has as its objective a listing of metallic couples that are compatible from a corrosion aspect and which still maintain a low contact impedance.
