In addition, it should be further noted that the number of the functional modules is not specifically limited in this embodiment, and fig. 1 specifically shows 7 functional modules, and if in the actual application process of the circuit board, other functional modules need to be laid in the circuit board, the technical solution provided in this embodiment may also be adopted, that is, under the condition that the functional attributes of the functional modules can be normally implemented, the functional modules with different functional attributes are laid in the circuit board provided in this embodiment.
Illustratively, taking the wireless fidelity module as an example, the functional attributes of the wireless fidelity module include that the wireless fidelity module can normally receive and transmit wireless signals (WIFI signals). Therefore, the wireless fidelity region needs to be disposed at a position close to the bottom of the circuit board, and particularly, the wireless fidelity region needs to be disposed at a position far away from the movement region, so as to prevent the wireless fidelity signal and the movement signal from interfering with each other.
For example, taking a movement module as an example, functional attributes of the movement module include that a signal line connecting terminal in the movement module needs to be exposed outside an electrical device main body for connection of an external signal input device, and the like, so that a movement region needs to be arranged at a left side or a right side of a circuit board.
