Method and device for analyzing and detecting open circuit and short circuit of PCB (Printed Circuit Board) design file and electronic equipment

Abstract

The invention relates to an open and short circuit analysis and detection method and device for a PCB design file and electronic equipment. The scheme comprises the steps of obtaining a Gerber file and an IPC file; loading an IPC file to construct an IPC network; loading a Gerber file and forming Gerber network; projecting the coordinates of the pins in the IPC network to the Gerber network; establishing a mapping relation according to a pin in the IPC network and a physical network hit by projection in the Gerber network, and respectively establishing a first mapping association table and a second mapping association table; detecting whether the PCB design file has open circuit or short circuit according to the first mapping association table and the second mapping association table, and displaying and storing the open circuit or short circuit. The method and the device have the advantages that open circuit and short circuit errors in the PCB design file can be quickly identified, the detection time is greatly shortened, and the open circuit and short circuit conditions can be completely avoided.

Description

technical field [0001] The invention relates to the technical field of PCB production, in particular to an open and short circuit analysis and detection method, device and electronic equipment of PCB design files. Background technique [0002] In the current PCB manufacturing process, the production is usually carried out according to the information provided by the customer, but the information provided by the customer is usually for the PCB design file or the Gerber file for the production data. When designing a PCB file, engineers need to export it to a Gerber file through PCB design software, and then roughly compare the network conditions in the Gerber file manually. It can only be found when there is an obvious inconsistency in the network (whether there is an open or short circuit); when the customer When only Gerber files are provided, there is no way to do manual comparison. There is no mother PCB design file. If only Gerber files are provided, manual comparison can...

Problems solved by technology

When designing a PCB file, engineers need to export it to a Gerber file through PCB design software, and then roughly compare the network conditions in the Gerber file manually. It can only be found when there is an obvious inconsistency in the network (whether there is an open or short circuit); when the customer When only Gerber files are provided, there is no way to do manual comparison. There is no mother PCB design file. If only Gerber files are provided, manual comparison cannot be performed. Because there is no mother PCB design file as a reference, I don’t know where the submitted Gerber files are. Has not been modified or damaged in the process prior to delivery

Therefore, if the error cannot be easily checked out directly according to the information provided by the customer, it will lead to defects in the subsequent PCB production.
