A method of providing a cover (2) on a substrate (1) to shield against radio frequency radiation, includes an electrically conductive material (5) -such as a conductive, possibly adhesive, paste- which shields against RF radiation and which is applied in a fluid state to the desired area of the substrate. The substrate may be a printed circuit board (1) or a base member of an RF housing. The wall member (3) is provided with a plurality of recesses to receive the material (5). <IMAGE> |
