Abstract: A lightweight radio/CD player for vehicular application is virtually “fastenerless” and includes a fold-up case formed of polymer based material that is molded to provide details to accept audio devices such as playback mechanisms (if desired) and radio receivers, as well as the circuit boards required for electrical control and display. The case is of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides EMC, RFI, BCI and ESD shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. Side wall closure members are extruded of aluminum defining self-engaging attachment features for affixing to the case, providing electrical self-grounding with the wire screen and thermal grounding with internal power devices.
