▎ 摘　　要

NOVELTY - The board has a heat guide layer (2) arranged with a mobile device and a back part of a protective layer (1) that is formed with a graphene thin film (11). A middle part of the protective layer and a side edge of the heat guide layer are formed with a decorate containing cavity (3). The heat guide layer is provided with a metal wire (21). An end of the metal wire is connected with the graphene thin film. The metal wire is connected with the moving device that is connected with a coupling point, where light transmittance range of the protective layer is greater than 80%. USE - Personalized mobile phone back board. ADVANTAGE - The board can enhance communication function, heat abstractor function and endurance function of a mobile device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a personalized mobile phone back board manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a personalized mobile phone back board.
