Problems solved by technology

[0003] The basic graphic exchange specification file contains preset hole parameters of different sizes and quantities, and the layout personnel need to measure each preset hole according to the preset hole parameters in the basic graphic exchange specification file, and after the measurement is completed Then retrieve the size parameters corresponding to each preset hole parameter from the database, and then merge the size parameters with the preset hole parameters one by one. Since the layout personnel process each preset hole in the above method, the processing time is also appear ineffective
[0004] And in the process of measuring the size of the preset hole by the layout personnel, due to the large number and size of the preset hole, it is easy to miss the measurement. Therefore, when the printed circuit board manufacturer completes the printed circuit board according to the wrong perforation parameters After the perforation operation, the perforation parameters were found to be wrong. At this time, a lot of time has been wasted and the printed circuit board manufacturer needs to be asked to perform the perforation operation of the printed circuit board again, which increases the manufacturing cost of the printed circuit board again.

Embodiment Construction

[0035] Please refer to figure 1 , is a flowchart of an embodiment of the present invention. Such as figure 1 As shown, the perforation generation method of the circuit diagram according to the embodiment of the present invention is applied to a circuit draft, and the circuit draft contains at least one preset hole, which specifically includes:

[0036] Step S100, read the default hole parameters, and the preset hole parameters can be, for example, the default hole parameters configured by the mechanism designer in the Basic Graphics Exchange Specification (IGES) file, for example, the aperture of the preset hole, the diameter of the preset hole Planar coordinate values ​​or preset hole tolerances.

[0037] Step S101, open the perforation database, and the perforation database includes at least a plurality of corresponding perforation parameters and parameter indexes, wherein the perforation parameters at least include perforation patterns, perforation dimensions, perforation...

Abstract

A circuitry punching creation method is characterized in that gaining corresponding punching parameters in a punching database according to the preset hole parameters in a circuit draft; meanwhile, provide the punching parameters on the circuit draft according to the position of the preset hole; moreover, provide a punching list on the circuit draft according to the punching parameters, so that relevant personnel can perform verification. The invention can improve the speed and correctness of the punching parameters that are created.

Description

technical field [0001] The invention relates to a method for generating component graphics of circuit diagrams, in particular to a method for generating perforations of circuit diagrams. Background technique [0002] In the process of designing and manufacturing printed circuit boards, the design parameters need to be completely provided to the printed circuit board manufacturer. The design parameters include GERBER groove and perforation parameters, and the GERBER file is an international standard optical drawing format file. It includes two formats, RS-274-D and RS-274-X, and the perforation parameters are measured by the layout personnel based on the information provided by the mechanical structure personnel in the basic International Graphics Exchange Specification (IGES) file. [0003] The basic graphic exchange specification file contains preset hole parameters of different sizes and quantities, and the layout personnel need to measure each preset hole according to the...
