Abstract:
A aesthetically appealing mounting system for an electronic device capable of forming a semi-conductive path for electro-static discharge. The mounting system can include an electrically conductive layer covered by a cosmetic anodized layer with multiple micro-perforations formed through the anodized layer exposing a small portion of the electrically conductive layer. The micro-perforations can be formed by laser-etching the cosmetic anodized layer to provide a grounding path while the micro-perforations remain visually undetectable. A semi-conductive wear layer can be configured to couple with the anodized layer. In some embodiments, the semi-conductive wear layer is in a recess on an electronic device. In some embodiments, the semi-conductive wear layer is comprised of a conformal conductive rubber.
