Description
Technical field
The present invention relates to PCB manufacturing technology fields, and in particular to a kind of short slot boring method of PCB.When slot parameter is in L
< 2D and when D < 51.9mil, solves the design method of such short slot curtailment and skew.
Background technique
Electronics industry is just towards micromation, and the direction of multifunction constantly rapidly develops, electronic circuit board process industry
Have to face such challenge, the aperture requirement of drilling is smaller and smaller, and borehole accuracy is higher and higher, and slot is also more and more.
And the fast development of national line board industry in recent years reduces cost so that the competition of the industry is increasing, improves production
Efficiency is already anxious at brows.However when meeting short slot (L < 2D) in machine drilling, usually made on pcb board
Slot figure selects the drill bit of 1/2 short slot diameter to convince pilot hole by patient analysis, then in guide hole respectively on the both sides of slot graphic length
On the basis of using diameter be equal to slot minor axis brill nozzle be overlapped drilling, this method not only seriously affects production efficiency, and
And due to during drilling superposition, since slot is drill-through on one side, it is easy to occur boring nozzle both sides discontinuity
Problem perplexs the processing of drilling operating, causes the finished product rate of good of PCB plate low so as to cause short slot skew and curtailment
Under, the production cost increases.
Summary of the invention
To solve drawbacks described above, the object of the present invention is to provide a kind of short slot boring method of PCB, this method is encountering brill
It when short slot (L < 2D), is avoided that nozzle both sides discontinuity situation is bored in appearance, improves short slot curtailment and skew is existing
As improving the rate of good of pcb board, reducing production cost.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: a kind of short slot boring method of PCB, feature exist
In: in the short slot boring procedure of PCB, drilled with rotating short slot seat calibration method, the short slot coordinate of rotation
Method is carried out counterclockwise or is rotated clockwise using the previous coordinate points of short slot as datum mark；
The short slot L < 2D and D < 51.9mil, wherein L represents short slot length, and D represents bit diameter.
Specifically, as the short slot L < 2D and D < 40mil,
When 2D < 0.9 0.75 < L/, borehole coordinate rotates clockwise 5 degree around datum mark, further, if L/ 2D≤
0.75, borehole coordinate rotates clockwise 7 degree around datum mark；
When 2D < 0.9 0.8 < L/, borehole coordinate rotates clockwise 7 degree around datum mark；
When 2D < 0.8 0.7 < L/, borehole coordinate rotates clockwise 10 degree around datum mark；
When 2D≤0.7 L/, borehole coordinate rotates clockwise 12 degree around datum mark.
The technical solution adopted in the present invention:
1. being produced in a manner of rotating slot coordinate to avoid such slot skew and curtailment.Coordinate rotation be with
The previous coordinate points datum mark of slot rotates counterclockwise: example: slot coordinate be X01456Y07895, G85, X01456Y07987,
Then the coordinate of datum mark is X01456Y07895, and rotation mode is as shown in Figures 1 and 2.To the same row of the same specification (or one
Column) short slot, datum mark need to only judge once, and the datum mark of the short slot of the same same row of specification (or one arrange) is same.But to non-
Slot in same horizontal line needs to make a decision again.The method of the present invention is especially solved as slot L < 2D and D < 51.9mil,
The processing method of such short slot curtailment and skew.
Note: to short slot, only the borehole coordinate in drilling formula is compensated, egative film and map file part do not compensate.
2. the method for the invention can cancel guiding hole machined, the molding hole count in short slot processing is effectively reduced, and
Slot skew and curtailment are avoided, production efficiency, save the cost can be greatly improved.

Specific embodiment
Such as the short slot boring method of PCB shown in Fig. 2,3,4,5, it is characterised in that: the short slot boring procedure of PCB
In, it is drilled with rotating short slot seat calibration method, the short slot coordinate method of rotation is with the previous coordinate of short slot
What point was carried out counterclockwise or was rotated clockwise as datum mark；
The short slot L < 2D and D < 51.9mil, wherein L represents short slot length, and D represents bit diameter.
Specifically, as the short slot L < 2D and D < 40mil,
When 2D < 0.9 0.75 < L/, borehole coordinate rotates clockwise 5 degree around datum mark, further, if L/ 2D≤
0.75, borehole coordinate rotates clockwise 7 degree around datum mark；
When 2D < 0.9 0.8 < L/, borehole coordinate rotates clockwise 7 degree around datum mark；
When 2D < 0.8 0.7 < L/, borehole coordinate rotates clockwise 10 degree around datum mark；
When 2D≤0.7 L/, borehole coordinate rotates clockwise 12 degree around datum mark.
