Abstract

In modern electronic systems efficient techniques that reduce unwanted electromagnetic interference (EMI) are needed. This paper describes the effects on electromagnetic shielding effectiveness (SE) of gaps caused by tolerance build up in various enclosure joint configurations. Four different joint geometries were considered. For simple joints, a sharp decrease on SE at larger tolerances was observed. Addition of bends in the joint geometry had a strong positive effect on the SE values. Increasing the effective length of the joint by increasing the angle of cut was demonstrated to increase the shielding performance.
