Detailed description of the invention
Below embodiments of the invention are described in detail:
Embodiment one
As it is shown in figure 1, the line layer described in the embodiment of the present invention is without copper area recognizing method, including walking as follows Rapid:
S101, line pattern file generated line layer region 10 and described line layer region 10 according to line layer In copper plate region 11, and described copper plate region 11 is shown in described line layer region 10 (referring to Fig. 5);
S102, determine described line layer region according to described line layer region 10 and described copper plate region 11 Multiple substrate regions 12 in 10, wherein, multiple described substrate regions 12 are spelled with described copper plate region 11 Synthesize described line layer region 10;Copper plate region 11 has copper plate, and substrate regions 12 includes Wu Tongqu Territory 121 and via regions 122, all do not have copper plate without copper region 121 and via regions 122.Substrate regions 12 distinguish whether to have copper plate with copper plate region 11.
S103, judge that the area of described substrate regions 12, whether more than the first preset area, will be greater than described the The described substrate regions 12 of one preset area is defined as without copper region 121.Wherein, the first preset area according to Area defined in region without copper 121 determines, if being defined as area more than 2 squares of English without copper region 121 Very little substrate regions 12, then the first preset area is 2 square inches;
S104, will determine as the described substrate regions 12 without copper region 121 and enter with described line layer region 10 Row display.
Above-mentioned line layer, without copper area recognizing method, first passes through line layer region 10, copper plate region 11 and obtains To multiple substrate layer area, then area is defined as Wu Tongqu more than the substrate regions 12 of the first preset area Territory 121, and will determine as showing with line layer region 10 without the substrate regions 12 in copper region 121.As This present invention can quick and precisely identify whether line layer has without copper region 121, and producers just can be for There is the line layer without copper region 121 take appropriate measures.
Embodiment two
As in figure 2 it is shown, the line layer described in the embodiment of the present invention is without copper area recognizing method, including walking as follows Rapid:
S201, line pattern file generated line layer region 10 and described line layer region 10 according to line layer In copper plate region 11, and described copper plate region 11 is shown in described line layer region 10 (referring to Fig. 5);
S202, the described copper plate region 11 in described line layer region 10 is shielded, and by described Remaining region in line layer region 10 shows, remaining region described is multiple described substrate regions 12 (referring to Fig. 6);
S203, obtain the central point of described substrate regions 12, by the edge of described substrate regions 12 with described The first preset area is inwardly reduced centered by central point;Wherein, the first preset area is according to without copper region 121 Defined area determines, if being defined as the area substrate regions more than 2 square inches without copper region 121 12, then the first preset area is 2 square inches.
S204, the described substrate regions 12 reducing described first preset area will be fewer than from described line layer Region 10 masks;The area of via regions 122 is less than the first preset area, is fewer than and reduces first Preset area, via regions 122 is the most all shielded.The area in region without copper 121 presets face more than first Long-pending, it is possible to for reducing the substrate regions 12 of the first preset area for without copper region 121.
S205, the edge of the described substrate regions 12 after described first preset area will be reduced with described central point Centered by outwards expand the second preset area and generate without copper identified areas 123 (referring to Fig. 7).Second The varying in size in the first preset area and could be arranged to less than the first preset area, so of preset area Identified areas without copper 123 generated in circuit layer region 10 is positioned at the inside without copper region 121, without copper Identified areas 123 can be used in identifying substrate regions 12 for without copper region 121 and can with without copper region 121 Distinguish.
S205, will determine as the described substrate regions 12 without copper region 121 and enter with described line layer region 10 Row display.
Embodiment three
As it is shown on figure 3, the line layer described in the embodiment of the present invention is without copper area recognizing method, including walking as follows Rapid:
