Problems solved by technology

[0004] Although the current PCB circuit board design also mentions signal protection and heat dissipation treatment, the method is not clear enough, there is no clear design method, and it is difficult to achieve strict control of circuit board protection
Although through empirical design, the circuit board can reach a certain safety level after multiple revisions, but it is easy to lose sight of one another and repeat the design, resulting in a waste of personnel, time and funds

Abstract

The invention provides a printed circuit board. The printed circuit board comprises an input and output interface, a communication device and a power module. Adjacent signals in the input and output interface are isolated through a ground network of a first preset separation distance. A ground network of a second preset separation distance is adopted in isolation of the communication device. The power module comprises at least one power part, and copper is laid on multiple layers below the power part. According to the printed circuit board, ground network shielding protection is carried out on sensitive signals on the circuit board, the anti-jamming capability of the signals is improved, radiated interference on external devices is reduced, enough heat dissipation space, namely, a heat dissipation channel is provided for a heating element, and therefore a thermosensitive component is well protected, and the service life of the component is prolonged. The invention further provides an electric car.

Description

technical field [0001] The invention relates to the technical fields of PCB circuit board design and automobile manufacturing, and particularly designs a printed circuit board and an electric automobile. Background technique [0002] Regardless of traditional vehicles or electric vehicles, the actual working environment is relatively harsh, such as large temperature changes in the working environment, serious electromagnetic interference, large vibration, noise pollution and so on. In order to adapt to these harsh working environments, high reliability requirements for auto parts came into being. Specifically, from a small bolt to a large engine, all components must meet the requirements of automotive safety levels. [0003] As more and more electronic units are added to the car, the originally limited layout space becomes more crowded. As the core controller of electric vehicles, the vehicle controller works in a high-radiation, high-temperature, and high-density working ...
