Abstract

The invention discloses a method and system for detecting that a component on a PCB is ultrahigh. The method comprises the steps that the layer of height information of a height limit area is opened to obtain the height limit area on the PCB; the limit height and the attribute of a limit box of the component in the height limit area are obtained; the layer, containing the height information, in the component is opened, the actual height of the component in the limit box is obtained; the actual height is compared with the limit height, and the ultrahigh component is obtained. The system comprises a PCB height limit obtaining module, a limit attribute obtaining module, a component height obtaining module and an ultrahigh component obtaining module. Compared with the prior art, by means of the method and the system, an ultrahigh component list can be quickly obtained, the situation that the ultrahigh components are artificially found in a DRC list term by term, so that the ultrahigh components are missed is avoided, the labor is saved, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of PCB board design, in particular to a method and system for checking the height of components on a PCB board. Background technique [0002] In the later stage of PCB design, engineers need to conduct a comprehensive and detailed inspection of the PCB board. This inspection includes a wide range of aspects, including the inspection of super high components. The height of the device involves actual operations such as assembly and use in the later stage. The problems caused by the super height of the device are displayed in the later stage of PCB production. The problems in the later stage cannot be modified and need to be redesigned. Therefore, checking the super height of the device is a PCB design. Indispensable link. [0003] In the prior art, it is judged by DRC (Design Rule Checking) in allegro (a PCB board design tool) whether there is superelevation. The DRC list includes all layers and types of des...
