An electronic device includes a chassis and a printed circuit board secured to the chassis. The printed circuit board includes a base plate, a bottom layer located above the base plate, and a ground plane located above the bottom layer. The bottom layer is located between the base plate and the ground plane; a plurality of copper pins are electrically connected to the base plate and the ground plane through the bottom layer; and the plurality of copper pins, the base plate, and the ground plane cooperatively define a faraday cage and shield the bottom layer from electromagnetic interference. |
