Rapid checking and changing method for PCB design file height information

The invention discloses a rapid checking and changing method for PCB design file height information. The method includes: opening a PCB data file by using allegro software, creating a function card inthe PCB data file, reading a set level of a PCB component by the function card to obtain initial height information, retaining the initial height information, and outputting a feedback value according to whether the initial height information exists or not. According to the invention, initial height information is reserved and a feedback value is output; based on this, a new attribute is createdto display the packaging height of a millimeter unit, an input field is created to write in component height information, and a component list report without height information is output according tothe authenticity of a feedback value, so that a designer can design a circuit board more effectively according to customer requirements, the efficiency is improved, the rework frequency is reduced, and the design period is shor
