Patent ID: 11304334

Abstract:
A vapor chamber includes an electromagnetic (EM) shielding layer. The vapor chamber is constructed from a structural base material that provides for a suitable size, strength, and/or weight for a specific application. The vapor chamber is treated at the region(s) to provide suitable EM shielding characteristics for the specific application. For example, an oxidation layer is removed from the region(s) to expose the structural base material while the vapor chamber is in an inert environment that prevents further oxidation. Then, while the vapor chamber remains within the same inert environment, a material having suitable electrical conductive properties is deposited onto the exposed structural base material to form an EM shielding layer at the region(s). When the vapor chamber is installed into an electronic device, the EM shielding layer may be electrically grounded so as to isolate one or more components within the electronic device from EM signal interference.
