Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of the invention and do not delimit the embodiments. It should be further noted that, for convenience of description, only some structures, not all structures, relating to the embodiments of the present invention are shown in the drawings.
Example one
Fig. 1 is a flowchart of a method for identifying a clogged pad area according to a first embodiment of the present invention, where this embodiment is applicable to a case where a clogged pad area is automatically identified, and the method may be implemented by a clogged pad area identifying apparatus, which may be implemented by software and/or hardware and integrated in a computer device that executes an embodiment of the present invention. Specifically, referring to fig. 1, the method specifically includes the following steps:
and S110, detecting a drilling dense area.
The patterned bonding pad is a bonding pad in a PCB and is connected with a copper sheet, and the bonding pad mainly has a cross shape and a rice-shaped shape. In general, each patterned pad may be composed of a plurality of drilled holes and a plurality of units, in the embodiment of the present invention, the number of the units is preferably 4, and may also be 2 or 6, and the embodiment of the present invention does not limit the number thereof.
Specifically, the drilling dense area is detected, that is, the area where a plurality of drilling holes are connected together is detected, and in the embodiment of the present invention, the connection area of the plurality of drilling holes is named as the drilling dense area.
Optionally, detecting the drill hole dense region may include: and amplifying the drill holes to set times, and determining the drill hole connection area as a drill hole dense area.
Specifically, the drilling holes of a plurality of patterned bonding pads included in the PCB design file are amplified, and after all the drilling holes are amplified to set times, whether the drilling holes are connected together is detected; if a plurality of drill holes are connected together, determining the area where the plurality of drill holes are located as a drill hole dense area. It should be noted that, in the embodiment of the present invention, the drilling hole may be enlarged by 0.5 times or 2 times, and the embodiment of the present invention does not limit the drilling hole, and different enlargement parameters may be set according to different PCBs. The number of the drilling dense areas related to the embodiment of the invention can be one or more.
For example, the drill holes of all the pads in the PCB design file may be enlarged by 2 times, after the drill holes are enlarged, it may be further detected whether a plurality of drill holes are connected together, and if it is detected that a plurality of drill holes are connected together, the area where the plurality of drill holes are located is determined as the drill hole dense area. For example, if 10 boreholes are detected to be enlarged and then connected together, the region where the 10 boreholes are located can be determined as the dense borehole region.
Optionally, after detecting the drill hole dense region, each patterned pad corresponding to the drill hole dense region may be copied to the target region.
Specifically, after detecting the drill hole dense region in the PCB design file, each of the pads corresponding to the drill hole dense region may be copied to the target region. The target area is a blank area, which may also be named as a temporary layer, and is not limited in the embodiment of the present invention. This has the advantage that the dense drilled area is copied to a blank area and subsequently processed without interference from other layers in preparation for more accurate identification of the clogged area of the pattern pad.
Illustratively, after detecting the drill-dense region, 10 flower pads corresponding to the drill-dense region may be copied to the temporary layer, wherein the detected drill-dense region contains 10 flower pads in this example.
And S120, respectively decomposing each patterned pad in the drilling dense area into a plurality of units.
Specifically, after the drill-dense region is detected and the plurality of pads included in the drill-dense region are copied to the target region, i.e., the temporary layer, the respective pads of the drill-dense region may be further decomposed into a plurality of cells, respectively.
For example, 10 flower pads included in the drilling dense region may be respectively decomposed into a plurality of cells. Preferably, 10 flower pads included in the drilling dense region may be respectively decomposed into 4 units.
S130, obtaining the distance between at least one unit in the plurality of units and the target drilling hole, and judging whether the target patterned bonding pad is blocked according to the distance.
Specifically, after each patterned pad in the drilling dense area is respectively decomposed into a plurality of units, the distance between at least one of the plurality of units and the target drilling hole may be further obtained, and whether the target patterned pad is blocked or not may be determined according to the distance between at least one of the plurality of units and the target drilling hole. The target patterned pad may be any patterned pad copied into the drilled dense area of the temporary layer, and is named as the target patterned pad for convenience of description of the embodiment of the present invention, which is not a limitation of the embodiment of the present invention.
For example, if the target patterned pad includes 4 units, the distances between the 4 units and the drill holes of the target patterned pad may be obtained, and whether the target patterned pad is blocked may be determined according to the distances between the 4 units and the drill holes of the target patterned pad.
Optionally, obtaining a distance between at least one of the plurality of units and the target drilling hole, and determining whether the target patterned pad is blocked according to the distance may include: if the distance between the target unit and the target drilling hole is smaller than or equal to a set threshold value, determining that the target patterned bonding pad is blocked; wherein the target unit is any one unit in at least one unit; and if the distance between the target unit and the target drilling hole is larger than a set threshold value, determining that the patterned welding disc is not blocked.
In a specific example of the embodiment of the present invention, the distance between the center point of the target unit and the center point of the borehole may be calculated by acquiring the center point of the target unit and the center point of the borehole, and the distance may be used as the distance between the target unit and the borehole. In the embodiment of the present invention, the distance between the target unit and the borehole may also be obtained by other methods, which are not described herein again in the embodiment of the present invention.
Specifically, after the distance between at least one of the plurality of units and the target via is obtained, whether the target patterned pad is blocked may be determined according to the distance, and the distance between the target unit and the target via may be compared with a set threshold, where the set threshold is preferably 6 microns or 5 microns, and the embodiment of the present invention does not limit the distance. The target unit is any one of at least one unit of the target patterned pad; if the target patterned pad includes 4 units, the target unit may be any one of the 4 units, which is not limited in the embodiment of the present invention.
For example, if the target unit is less than or equal to 6 microns from the target borehole, then the target land blockage may be determined. In a specific example of the embodiment of the present invention, if the distance between the target unit and the target drilling is 0, the target unit may be considered to be in contact with the target drilling, and at this time, the target land is blocked. If the target unit is more than 6 microns from the target borehole, then the target land blockage can be determined.
The embodiment is realized by detecting a drilling dense area; respectively decomposing each patterned bonding pad in the drilling dense area into a plurality of units; the distance between at least one unit in the units and the target drilling hole is obtained, whether the target patterned bonding pad is blocked or not is judged according to the distance, automatic identification of the blocked area of the patterned bonding pad is achieved, the problems that manual identification is long in time consumption and detection omission can occur are solved, and cost can be reduced.

Specifically, referring to fig. 2, the method mainly includes the following steps:
and S210, detecting a drilling dense area.

And S230, acquiring the distance between at least one unit in the plurality of units and the target drilling hole, and judging whether the target patterned bonding pad is blocked according to the distance.
And S240, cutting the target unit to enable the target patterned pad to be connected.
Specifically, after the distance between at least one of the plurality of cells and the target via is obtained and the target via is determined to be blocked according to the distance, the target cell may be subjected to a cutting process, for example, the target cell is cut off, or a via is cut in the target cell, so as to make the target via.
Illustratively, if the target pad is pad a, and pad a includes 4 cells, the 4 cells are cells a, b, c, and d, respectively. If the distance between the unit a and the drill hole of the pad a is 0, the unit a is considered to be in contact with the drill hole of the pad a, and the unit a can be subjected to chipping processing.
In this embodiment, on the basis of the above embodiment, after the target land blockage is determined, the target cell may be cut to enable the target land to pass through, so that the land blockage area can be automatically identified, and the blockage area can be processed.
