Abstract

The present invention concerns a reinforced conductive layer (7). The layer is applied at a part (3a,b) of an electrical unit, e.g. a mobile telephone, which is to come into contact with another part (3a,b). The layer (7) will protect the covered material against corrosion due to formation of a galvanic element. In a preferred embodiment of the invention the layer (7) is made of the made material as the part (3a,b) which it will come into contact with. Furthermore, spaces (16) may be formed in assembly of a mobile telephone, which spaces (16) are surrounded by conductive material. (FIG. 1)
