Abstract
The invention relates to a manufacturing method of a figure 8 shape hole of a printed circuit board. The method comprises the following steps: 1) Firstly drilling a guide drill hole; 2) Then drilling a first circular hole; 3) And then drilling a second circular hole; 4) Finally drilling a heavy drill hole. Compared to the prior art, by using the method of the invention, there are the following advantages that working hours and manpower are saved; quality and a yield rate are high and so on.
Description
Technical field
The present invention relates to a kind of correlation technique of printed circuit board, especially relate to the manufacture method in a kind of printed circuit board 8-shaped hole.
Background technology
Wiring board is being produced Eight characters hole, when hardy hole and each tangent special hole, connect the place at place in the hole, produce very large burr, whole hole shape is rough, as shown in Figure 1 and Figure 2, can find out from above two figure, among Fig. 1 and Fig. 2, distinguish the lower cutter priority of boring with two numerical orders, according to the size (diameter) of tangent position between the Kong Yukong, increase the weight of boring (client without specific (special) requirements time).
In the production process such as Fig. 3, subdrilling 1 bores 2 again, bores at last 3 (heavily boring), and Yin Maoci is the flexible materials such as filament, wind-engaging or stressed after can swing.Thereby it is unclean to cause burr to be removed, and the hole is yielding, processes unusually so can increase flow process: boring-polishing-manpower (hairbrush) burr brushing-polish-brush-high-pressure washing-oven dry.Manpower in the above flow process (hairbrush) burr brushing is: jagged hole hairbrush wiping in every PNL plate, so that minimizing or remove the hole inner burr, and not only waste of manpower and more expend man-hour of this measure.
Summary of the invention
Purpose of the present invention be exactly provide a kind of in order to overcome the defective that above-mentioned prior art exists and more save manpower and man-hour, the manufacture method in printed circuit board 8-shaped hole that quality yield is high.
Purpose of the present invention can be achieved through the following technical solutions:
The manufacture method in a kind of printed circuit board 8-shaped hole is characterized in that,
1) boring is led in subdrilling;
2) bore again the first circular hole;
3) bore again the second circular hole;
4) bore at last heavily boring.
Described the first circular hole and the second circular hole are arranged in a crossed manner, and described heavy boring is with the first circular hole and the second circular hole crosspoint line ellipse as major axis, described the attach most importance to inscribed circle structure of boring of boring of leading.
Compared with prior art, the present invention more saves manpower and man-hour than prior art, and after the quality tracking through January, draws quality yield of the present invention and be promoted to present 98% by former 75%.
Description of drawings
Fig. 1 is the drilling technique mode figure in existing formed objects hole;
Fig. 2 is the drilling technique mode figure of the large aperture of existing difference;
Fig. 3 is existing boring flow chart;
Fig. 4 is technical approach figure of the present invention;
Fig. 5 is flow chart of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 4, printed circuit board 8-shaped hole comprise lead boring the 1, first normal circular hole 2, the second normal circular hole 3, heavily hole 4, what increase tangent position same diameter at the 4 tangent places that heavily hole leads boring 1, increases first to lead boring and can effectively reduce or avoid the hole that causes because of the second normal circular hole 3 unbalance stress askew before boring.
In the production process such as Fig. 5,1) boring 1 is led in subdrilling; 2) bore again the first circular hole 2; 3) bore again the second circular hole 3; 4) brill heavily holes 4 at last, and at the askew and burr phenomena of the complete rear atresia of boring.
Claims (2)
