Abstract
A circuit board includes an upper surface, a lower surface, a first end surface connecting the upper surface and lower surface, and a heat dissipation block. The first end surface of the circuit board has an open slot, the open slot extending through the upper surface and lower surface, and the heat dissipation block being arranged inside the open slot. The heat dissipation block has a first surface, the first surface facing away from the lower surface of the circuit board and extending to the first end surface of the circuit board. The inside of the open slot has a stop structure, the stop structure preventing the heat dissipation block from moving toward the first end surface of the circuit board.
