Abstract
A housing assembly for a lightweight electronic device for vehicular application is virtually “fastenerless” and includes a one-piece case formed of a layered composite structure including polymer based, electrically insulating sheet material and electrically conductive sheet material that is compression molded or hydroformed to provide three-dimensional case details to accept one or more electronic devices such as circuit boards required for electrical control and display of vehicle based systems. The conductive sheet material is preferably a wire mesh which provides shielding from electrical anomalies and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. Major components and subassemblies are self-fixturing during the final assembly process, eliminating the need for dedicated tools, fixtures and assembly equipment.
