Abstract
Present invention offer one kind is square copper slotted eye boring method.Described square have copper slotted eye boring method to comprise the following steps：（1）According to there is copper slotted eye design size, the preboring circular hole on four angles for having copper slotted eye；（2）Oval slotted eye is drilled out with the brill nozzle equal with slotted eye width and compensation；（3）Choose can be tangent with both sides on elliptical slot angle of spot hole brill nozzle bore circular hole deburring processing is carried out successively to elliptical slot angle of spot hole.The present invention has copper slot orifice plate for PCB is square, can realize it is one-stop be drilled, improve production efficiency, save entreprise cost；It it also avoid deviation caused by the secondary positioning in hole in same sheet simultaneously, it is ensured that same all apertures of sheet are once drilled, it is ensured that machining accuracy, ensure production quality.
Description
Technical field
The present invention relates to board production technical field.
Background technology
Existing printed substrate processing procedure field, there is a copper slotted eye for square, generally use mode is to bore after substrate sawing sheet
Basic hole, return again to CNC process gongs and go out square slotted eye, finally turn to electroplate copper facing.In this processing procedure, one of CNC gong groove work is added
Sequence, gong hole need secondary positioning, are easily caused slotted eye skew, and quality hidden danger is big, while increases by a procedure, per square meter cost increase 10
Member or so.For it is this it is square have copper slotted eye, also a kind of mode is once to be drilled to type in drilling machine, but the slotted eye corner position drilled out
Put irregularly, as shown in figure 1, the slot size shape can not meet client's quality requirements.
The content of the invention
In view of the above-mentioned problems, the present invention provides, one kind is square copper slotted eye boring method.
It is of the present invention it is square have copper slotted eye boring method, comprise the following steps：
（1）According to there is copper slotted eye design size, the preboring circular hole on four angles for having copper slotted eye；
（2）Oval slotted eye is drilled out with the brill nozzle equal with slotted eye width；
（3）Choose can be tangent with both sides on elliptical slot angle of spot hole brill nozzle bore circular hole deburring is carried out successively to elliptical slot angle of spot hole
Processing.
Preferably, step（1）Described in Circularhole diameter be 0.5-0.6 mm.
Preferably, step（2）The middle brill nozzle using than the mm of slotted eye width compensation 0.1 is drilled.
Compared with prior art, the beneficial effects of the present invention are：（1）The present invention has copper slot orifice plate, energy for PCB is square
Enough realize it is one-stop be drilled, improve production efficiency, save entreprise cost.（2）There is copper slot orifice plate for PCB is square, realize a station
Formula is completed, and it also avoid deviation caused by the secondary positioning in hole in same sheet, it is ensured that and same all apertures of sheet are once drilled,
It ensure that machining accuracy.（3）Boring method of the present invention solves in existing one-stop bore mode that square groove angle is irregular,
Radian is excessive and draws and enters problem in hole, so as to cost-effective while, ensure production quality.
Brief description of the drawings
Fig. 1 is boring method schematic flow sheet of the present invention.
Embodiment
For the ease of it will be appreciated by those skilled in the art that being done below in conjunction with specific embodiment to the present invention further detailed
Description.
Referring to Fig. 1, it is of the present invention it is square have copper slotted eye boring method, be the subdrilling on square four angles of slotted eye
Four are drawn hole, then drill out oval slotted eye with the brill nozzle equal with slotted eye width, with finally with the brill nozzle tangent with two sides on angle
To bore circular hole and carry out deburring processing, such a brill method can reach square slotted eye ideal effect, and all steps are all completed on drilling machine, and one
Secondary positioning can be completed, and effectively prevent various problems caused by secondary position error.
When it is implemented, needing first according to the design size for having copper slotted eye, suitable brill nozzle is chosen, typically chooses 0.5-
0.6 mm brill nozzle, four circular holes of preboring on four angles for having copper slotted eye, then bore slotted eye.When boring slotted eye, typically
From the brill nozzle equal with slotted eye width, taken up space by compensation copper sheet, 0.1mm preferably bigger than slotted eye width brill nozzle drills out ellipse
Circular slotted eye.
Finally, brill nozzle that can be tangent with both sides on elliptical slot angle of spot hole is chosen, circle is bored on each angle of oval slotted eye
Hole, deburring processing is carried out successively to elliptical slot angle of spot hole, obtain oval slotted eye as depicted.
The method of the invention has copper slot orifice plate for PCB is square, can realize one-stop completion, it is not necessary to which go further CNC
Gong plate flow, friendship phase and limp timeliness are improved, each square meter of wiring board can save 10 yuan of costs, if monthly producing such plate
5000 square meters, moon saving is more than 50000 yuan.On the other hand, it is secondary fixed to it also avoid hole in same sheet for one-stop completion drilling
Deviation caused by position, it is ensured that same all apertures of sheet are once drilled, it is ensured that machining accuracy.Other drilling of the present invention
Method solves in existing one-stop bore mode that square groove angle is irregular, and radian is excessive and draws and enters problem in hole, so as to save
About cost while, ensure production quality
It is the specific implementation of the present invention above, its description is more specific and detailed, but therefore can not be interpreted as to originally
The limitation of patent of invention scope.It should be pointed out that for the person of ordinary skill of the art, structure of the present invention is not being departed from
On the premise of think of, various modifications and improvements can be made, these obvious alternative forms belong to the protection of the present invention
Scope.
