NOVELTY - The utility model claims a high stability flexible circuit board with long service life, comprising a bearing layer, the inner side of the lead pattern layer fixedly connected with covered with a lower covering film, the top of the bearing layer fixedly connected with a first protective layer, the top of the first protective layer fixedly connected with a scratch-proof layer; the bottom of the bearing layer fixedly connected with with a second protective layer; the filling layer is filled with graphene; the bottom of the filling layer fixedly connected with with a heat conducting plate; the heat conducting plate is uniformly distributed with heat dissipation pore, the bottom of the heat conducting plate is connected with a block fixedly connected with fan. In the utility model, the top part of the lead pattern layer is provided with an upper covering film; a first protective layer and a scratch-proof layer; the bottom is provided with a lower cover film and the second protective layer can effectively reduce the shock effect; heat dissipation pore surface area and the exhaust fan increase the air flow speed can effectively radiate, prevent damage caused by heat deformation; it is worthy of popularization.
