Abstract

The invention discloses a PCB package design method of an integrated security distance automatic check function. The method comprises the following steps: S10, establishing a PCB package of a high-pressure device, wherein the set parameter comprises the body size of the high-pressure device; S20, setting electric clearance automatic check, and adding a device arrangement prohibition area at the outside of the high-pressure device body at a TOP layer; S30, setting creep distance automatic check; if the device is a plug-in device, setting wiring arrangement prohibition areas at all layers; if the device is a patch device, setting the wiring arrangement prohibition area at the TOP layer. The PCB package design method disclosed by the invention can realize security distance automatic check, and can be called as the standard part, the efficiency is obviously improved, and the careless omission in the artificial check can be avoided.

Description

technical field [0001] The invention belongs to the field of electronic devices, and relates to a PCB packaging design method integrating a safety distance automatic inspection function. Background technique [0002] On the printed circuit board (Printed Circuit Board, PCB), for high-voltage electronic components (36V and above voltage), it is necessary to meet a certain safety distance with other circuits or other electronic components. The safety distance includes electrical clearance and creepage. electrical distance. Among them, the electrical clearance refers to: the shortest distance between two conductors in the air; the creepage distance refers to: the shortest distance between two conductors along the surface of the insulating material. The existing safety distance inspection is mainly completed by manual measurement, that is, in PCB design, whether the distance between high-voltage electronic components meets the safety distance requirements can only be judged by ...
