Abstract
The invention relates to a method for machining holes in printed boards. The method includes 1), drilling the holes according to drilling files; 2), preparing hole milling files; 3), milling the holes according to the hole milling files, and the like. The method has the advantages that when the hole milling files are prepared in the step 2), preliminarily compiled macro-programs are invoked by the aid of macro-language in CAM (computer-aided manufacturing)350 software, and only drilling-to-hole-milling switching parameters need to be inputted and selected, so that the hole milling files can be automatically generated, the hole milling machining efficiency and accuracy can be greatly improved, and human errors due to manual operation can be eliminated.
Description
Technical field
The invention belongs to printed board and make field, relate to a kind of processing method of printed board hole.
Background technology
Along with the develop rapidly of printed board, the components and parts in printed board are more and more intensive, and the heat dissipation capacity of unit are is also increasing, and high density PCB must use high Tg sheet material could meet heat-resisting requirement.High Tg sheet material is in improving the glass transition temperature of sheet material, and sheet material hardness increases to some extent, toughness drop.In the time boring larger hole, often can produce hickie at bore edges, cause the percent defective of drilling operating to increase.
Through overtesting, larger hole is adopted to the method for hole milling, bore edges can not produce hickie.But meeting increase the operation of one hole milling afterwards in boring like this.
Hole milling need to first generate hole milling file, the method that generates hole milling file under existence conditions mainly contains 2, first method is that boring file is imported in CAM software, draws one by one circle according to position and the diameter of boring, then enters Nc Editer the figure of finishing is converted to hole milling milling file.Second method is that boring file is exported as after * .dxf file and opened with Autocad, according to the position, hole and the diameter that import, draws one by one circle in Autocad, generates hole milling figure.
Owing to only having larger hole just to need hole milling, above two kinds of methods all need the macropore of artificially selecting needs to change, and the manual circle of drawing, generates hole milling figure one by one, all exist making hole milling file efficiency low, easily produce the shortcoming of mistake.
Summary of the invention
Add for solving current printed board hole the technical problem that the preparation method efficiency of hole milling file in man-hour is low, easily produce mistake, the invention provides a kind of processing method of printed board hole.
Technical solution of the present invention is as follows:
A processing method for printed board hole, comprises the following steps:
1] according to the boring of boring file:
2] prepare hole milling file;
3] according to hole milling file hole milling;
Its special character is: described step 2] comprise the following steps:
2.1] will hole in file importing CAM software;
2.2] input need transfer the aperture parameters of the minimum aperture of hole milling file to;
2.3] the every class in the boring file cutter table that scanning imports is bored brill cutter number, bore size, the drilling hole amount of cutter, obtains the parameter information of all kinds of borings, and the parameter information of all kinds of borings is temporary;
2.4] formation of hole milling file:
2.4.1] create an interim boring layer, and by step 2.3] in the size of all kinds of borings that provide of the parameter information of all kinds of borings compare with the aperture parameters of minimum aperture one by one:
If the aperture of such boring of being compared is more than or equal to the aperture of minimum aperture, such boring is copied in interim boring layer, form interim boring file;
Derive the interim boring file of this layer, and delete this interim boring layer;
2.4.2] scanning step 2.4.1] in the interim boring file that generates, the hole milling parameter information of the brill cutter that obtains comprising all kinds of borings number, bore size, drilling hole amount and coordinate, and hole milling parameter information is temporary;
2.4.3] create a light paint layer, create a D code, integrating step 2.4.2 simultaneously] in temporary hole milling parameter information, light paint layer draw circle, generate hole milling path;
2.4.4] enter boring editing machine, the hole milling path that upper step is generated is converted to hole milling file;
3] according to hole milling file hole milling.
The invention has the beneficial effects as follows:
The processing method of a kind of printed board hole of the present invention, in the time preparing hole milling file, macrolanguage in application CAM350 software is called the macroprogram of finishing in advance, as long as input and select boring to turn the parameter of hole milling, can automatically generate hole milling file, improve greatly working (machining) efficiency and the accuracy rate of hole milling, eliminated the human error that manual operations causes simultaneously.

The specific embodiment
Illustrate the specific embodiment of the present invention below:
A processing method for printed board hole, comprises 1] according to the boring of boring file; 2] prepare hole milling file; 3] according to hole milling file hole milling.Wherein step 2] can carry out by the following method:
Manual importing will transfer the boring file of hole milling to, and system ejects dialog box (see figure 2), and the following boring of input or selection turns the parameter of hole milling:
1,, according to drilling operating working ability, input need be converted to the minimum diameter of the boring of hole milling;
2, input milling cutter diameter, the relieving amount of the hole milling program that this parameter determination procedure produces is how many, also can be made as 0, and relieving amount is set flexibly in the time of hole milling;
3, the hole milling filename that input is derived;
4, select whether transfer 3.175 hole to hole milling, the hole due to 3.175 is generally the milling plate locating hole adding in engineering preparation, so need not transfer this hole to hole milling; But in the time having 3.175 hole in printed board plate, just need to transfer this hole to hole milling the hole milling figure that then the outer milling plate locating hole of manual deletion plate changes into.
Scan every class in this boring file cutter table and bore the brill cutter number of cutter, bore size, drilling hole amount, and by these information temporary storages.
A newly-built interim boring layer, copy this layer (according to the hole of whether selecting to change 3.175 in upper step dialog box by meeting all kinds of macropores of minimum-value aperture that need transfer hole milling to, select whether to copy into such hole), derive after this layer of boring file (text), delete this temporary layer.
The boring file generating in step in scanning, the brill cutter of all kinds of borings number, bore size, drilling hole amount and coordinate is temporary.
A newly-built light is painted layer, and a newly-built suitable D code, according to the coordinate information of the brill cutter of storing in array number, bore size, drilling hole amount and all kinds of macropores, is drawn circle at this layer, generates hole milling path.
Enter boring editing machine, the hole milling path that upper step is generated is converted to milling file (with the milling cutter diameter parameter cutter relieving of inputting in dialog box), then the milling file of generation is exported as to Excellon Route form (with the filename preservation of inputting in dialog box), can directly on CNC milling machine, use.
A newly-built boring layer, copies 3.175 hole into this layer, then preserves with the filename of inputting in dialog box and derives (different from the file suffixes that upper step is preserved), generates milling plate locating hole file.If 3.175 Kong Quan is milling plate locating hole in boring file, the file of deriving can be used as the positioning hole drilling file of milling plate, otherwise needs manual modification.
