Embodiment Construction

[0054] In view of the deficiencies in the prior art, the inventor of this case was able to propose the technical solution of the present invention after long-term research and extensive practice. The technical solution, its implementation process and principle will be further explained as follows.

[0055] The invention writes a program file for checking the repeated resistance in the printed circuit board and saves it as a callable file format of the circuit board design software, and the circuit board design software calls the program file to perform the repeated resistance check.

[0056] Common printed circuit board (Printed Circuit Board, PCB) design software includes Protel, Mentorpads, Cadence Allegro, etc. Taking Cadence Allegro software as an example, the inspection of PCB design can be realized through the secondary development of its SKILL platform. For example, in the embodiment of the present invention, the SKILL program for checking the repeated resistance in the...

Abstract

The invention discloses a method and a device for checking repeated resistance in a printed circuit board. The method for checking the repeated resistance in the printed circuit board compiles an executable program used for the repeated resistance in the printed circuit board, and stores the executable program as a callable file format for circuit board design software, and the circuit board design software calls the executable program to execute the checking of the repeated resistance. By use of the technical scheme of the invention, during circuit board design, the repeated resistance can bequickly checked, a position with problems is positioned, a report is output to a relevant engineer to check, checking time is greatly shortened, and working efficiency is improved.

Description

technical field [0001] The invention relates to a layout checking method of a printed circuit board, in particular to a method and device for checking repeated resistance in a printed circuit board, and belongs to the technical field of printed circuit board design. Background technique [0002] With the development of the market and technology, the integration of circuit boards is getting higher and higher, the size is getting smaller and smaller, the cost pressure is getting bigger and bigger, and the time to market is getting shorter and shorter, so PCB (Printed Circuit Board, printed When designing circuit boards, the considerations of cost, quality, and first-time success rate are issues that every engineer should pay attention to. Usually the circuit board design process is: schematic design - circuit board design - manufacturing and processing - debugging. If there are errors in the schematic diagram that are not checked out during the design process, then there will...
