NOVELTY - The utility model claims a white steel sheet reinforcing member, comprising a reinforcing plate, which is used for increasing the whole strength of the circuit board, a first locating groove, which is opened on the reinforcing plate; a white ink layer, which is covered on the bottom of the reinforcing plate, for protecting the surface of the reinforcing plate. The utility model is provided with an anti-interference radiating layer, the supporting plate and the side plate form a tower-shaped structure, so that there is a gap between the anti-interference structure and the reinforcing plate, convenient for ventilating and radiating, at the same time, the supporting block upper end generate polarization force to absorb the reinforcing plate, the reinforcing plate is fixed stably, the supporting plate and the side plate are made of material graphene it can increase the heat transfer of the reinforcing plate upper end auxiliary radiating, increasing the radiating performance of the circuit board.
