摘要

Gasketed seams are a primary pathway for electromagnetic leakage in enclosures, and corrosion at these seams can significantly worsen the leakage. Therefore, this work investigates the degradation of shielding effectiveness (SE) in enclosures with gasketed seams when exposed to corrosive environments. Since corrosion products typically exhibit low electrical conductivity, a simulation analysis is first conducted to examine how variations in seam conductivity affect the SE of the enclosure. Subsequently, experiments are conducted on the enclosure with gasketed seams to evaluate changes in its SE after being exposed to a corrosive environment. Experimental results show that enclosures with gasketed seams exhibit a significant decline in SE when exposed to corrosive environments. For improving the SE of enclosures and mitigating the adverse effects of corrosion, installing electrically conductive rubber gaskets is a more effective solution than using finger stock gaskets.
