Example Embodiment

[0034] The core of the present invention is to provide an effective grid point arrangement method for PCB design tools, so that different areas can be provided with grid points required by the design during the PCB design process, and different areas correspond to different grid point arrangements. For example, the 1MM BGA provides 0.5MM grid points, the 1.27MM BGA provides 25mil grid points, etc.; in this way, CAD engineers only need to complete the grid setting once, and do not need to frequently perform grid points in future designs. Set up.

[0035] In a nutshell, the present invention sets different grid points for different areas, and the process of arranging the grid points for each area can be divided into two situations: one is that different areas correspond to different grid points. At the same time, it is arranged in the PCB design file. When the PCB designer switches and designs in different areas, there is no need to perform grid layout operations; the other is to pr...

Abstract

The invention relates to a realization method of region grid point in PCB design. The invention sets different grid points for different regions at only one time in PCB design process. It also provides an implementation method of regionization arrangement of grid point so that in the process of PCB design, no matter how frequent it is to switch among different regions, design that is based at different grid point is convenient. The invention largely enhances efficiency of PCB design.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for realizing regional grid points in PCB (printed circuit board) design. Background technique [0002] With the development of electronic technology and the needs of PCB design, various PCB design tools are continuously provided to PCB designers. [0003] In the process of PCB design, in order to improve the accuracy and efficiency of design, it is usually necessary to provide corresponding grid points in the area of ​​PCB design as a reference for PCB design. That is to say, during the PCB design process, a large number of various types of devices may be included in one area of ​​the PCB file page, and different grid support is required for the design of each type of device to efficiently complete the design. For example, 1MM BGA (Ball Grid Array) needs 0.5MM grid points, 1.27MM BGA needs 25mil grid points, etc. Usually, a PCB needs at least four or five types of ...
