Abstract
A circuit board assembly includes a circuit board, a noise source and a shielding cover. The circuit board has an upper surface, a lower surface and a plurality of grounding areas. The lower surface faces away from the upper surface, and the grounding areas are located at the lower surface. The noise source is located at the upper surface of the circuit board. The shielding cover includes a covering body and a plurality of elastic grounding arms. The covering body is in contact with the upper surface and covers the noise source. The elastic grounding arms are connected to the covering body. The elastic grounding arms are in contact with the lower surface of the circuit board and respectively in electrical contact with the grounding areas.
