Abstract
A layer may be produced on the surface of a detail to thereby provide electromagnetic radiation shielding. The layer (e.g., a metallic layer) is transferred either directly or indirectly onto the detail, which may be all or a portion of, for example, a telephone casing. The transfer may be effectuated through a variety of techniques. For example, a tampon pad may be crafted to conform to the surface of the detail. After the tampon pad is coated by collecting the layer (e.g., from a foundation onto which the layer was pressed through a screen frame or from an etched plate), the layer is transferred to the detail from the tampon pad. Additional examples include transferring the layer by using a screen printing method or by sinking the detail into a fluid bath.
