Abstract
An electronic device, such as a notebook computer, includes a main board housed in a casing that is at least partly constituted by a conductive member. A grounding path is established between the main board and the casing by arranging a resilient grounding tab, made of a conductive material, between the main board and the casing. The grounding tab has a U- or V-shape including first and second limbs. The first limb is positioned on the main board with a free end of the second limb engaging the casing and maintaining secured engagement with the casing by means of elastic deformation thereof. The first limb has legs perpendicularly extending therefrom for inserting into through holes defined in the main board. The legs are soldered to the main board by through-hole techniques to fixedly mount the grounding tab to the main board. A secured grounding path is thus established between the main board and the casing for suppressing electromagnetic interference of the electronic device.
