Abstract
The invention discloses a PCB manufacturing method for modifying crooked short grooves and a PCB. The manufacturing method comprises the steps that when a grooving cutter is used for drilling grooves, the point where the cutter firstly cuts is regarded as the circle center, the angle pre-compensation value of the grooves is increased in the clockwise direction, and the crooked short grooves are modified. According to the PCB manufacturing method, when the grooving cutter is used for drilling grooves, the point where the cutter firstly cuts is regarded as the circle center, the angle pre-compensation value of the grooves is increased in the clockwise direction, and the crooked short grooves are modified, so that product quality is guaranteed, and the purpose of improving production efficiency is improved.
Description
Technical field
The present invention relates to circuit board technology field, more particularly to a kind of PCB plate production method askew for improving short groove groove
And pcb board.
Background technology
In prior art, the short groove processing method of pcb board is usually at present first to add drill hole at groove two ends, reuses groove knife brill
Go out short groove, but process short groove by this method, for the short groove of flute length≤2 times groove width, then it is askew to produce groove, can only during production
By reducing folded number come management and control, it is impossible to thoroughly improve the askew phenomenon of short groove groove, and reduce production efficiency.
Therefore, prior art has yet to be improved and developed.
The content of the invention
In view of above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of PCB askew for improving short groove groove
Board manufacturing method and pcb board, it is intended to solve the problems, such as that the short groove processing method of existing pcb board cannot improve short groove groove askew.
Technical scheme is as follows：
A kind of PCB plate production method askew for improving short groove groove, wherein, including step：
When drill flute is carried out using groove knife, following knife point is the center of circle, angle of the v-groove pre-compensation value is increased clockwise, to change
The groove of the kind short groove for getting out is askew.
The described PCB plate production method askew for improving short groove groove, wherein, the flute length≤2 times groove width of the short groove.
The described PCB plate production method askew for improving short groove groove, wherein, angle of the v-groove pre-compensation value is 3 ~ 5 degree.
The described PCB plate production method askew for improving short groove groove, wherein, angle of the v-groove pre-compensation value is 4 degree.
The described PCB plate production method askew for improving short groove groove, wherein, got out by G85 instructions using groove knife short
Groove.
A kind of pcb board, it is characterised in that made using preparation method as above.
Beneficial effect：The PCB plate production method of the present invention, when drill flute is carried out using groove knife, following knife point is the center of circle, suitable
Clockwise increases angle of the v-groove pre-compensation value, askew with the groove for improving the short groove for getting out, and both ensure product quality so as to reach, and
The purpose of energy improve production efficiency.
Description of the drawings
Fig. 1 be prior art in short groove processing occur groove it is askew when structural representation.
Fig. 2 is the structural representation in the present invention when adding man-hour to compensate.
Specific embodiment
The present invention provides a kind of for improving the askew PCB plate production method of short groove groove and pcb board, to make the mesh of the present invention
, technical scheme and effect it is clearer, clear and definite, below the present invention is described in more detail.It should be appreciated that described herein
Specific embodiment only to explain the present invention, be not intended to limit the present invention.
A kind of PCB plate production method preferred embodiment askew for improving short groove groove provided by the present invention, it includes step
Suddenly：
When drill flute is carried out using groove knife, following knife point is the center of circle, angle of the v-groove pre-compensation value is increased clockwise, to change
The groove of the kind short groove for getting out is askew.
As shown in figure 1, when being processed using conventional method, following knife point 100 is the center of circle, in short groove counter clockwise direction
Distort, and conventional method can only be by reducing folded number come the askew problem of management and control groove.As shown in Fig. 2 the present invention passes through following knife point
100 is the center of circle, and an angle of the v-groove pre-compensation value is increased clockwise, so as to offset with the angle of distortion in counter clockwise direction
Disappear, thoroughly solve the askew problem of groove.
I.e. when drilling makes, the lower knife point 100 with groove knife increases angle of the v-groove pre-compensation value as the center of circle, clockwise, and nothing
Drill hole is needed, so both accomplished that the askew problem of groove occurred in the short groove of improvement, and without the need for reducing folding number to carry out management and control, so improving
Production efficiency, in turn ensure that product quality.
Further, the flute length≤2 times groove width of the short groove, that is, assume that groove width is s, and flute length should be less than 2s, the side of the present invention
Method is particularly suitable for the short groove processing of this kind of specification.
In the present invention, angle of the v-groove pre-compensation value is 3 ~ 5 degree.Even more preferably, angle of the v-groove pre-compensation value is 4 degree.Enter one
Step, short groove is got out using during groove knife by G85 instructions.
For below Φ 1.5mm plus nozzle of harding lead often bores 2.0mm thick plates, and deflection angle is 3 ~ 5 degree, and often changes deflection
Then angle inclines 3 degree to 0.05mm.
For example, the brill nozzle program for Φ 1.0mm can be amended as follows：
XYG85X1.0Y0 is revised as：XYG851.0Y-0.05；
Or XYG85X0Y1.0 is revised as：XYG85X0.05Y1.0
In addition, can also simultaneously coordinate the knife speed for reducing groove knife askew to solve the problems, such as groove,
Additionally, can also increase prebored hole, such as groove width is 0.8mm, before this groove is bored, the knife under the groove knife of two respectively
Point increases the hole of 0.4mm or 0.5mm, plays guiding function, and it is concentric circles to need, that is, descend knife point and prebored hole to be same circles
The heart.In addition, plus man-hour even more preferably bore nozzle using the shorter slot of sword length.
Based on above-mentioned preparation method, the present invention also provides a kind of pcb board preferred embodiment, and it adopts making as above
Method is made.
In sum, PCB plate production method of the invention, when drill flute is carried out using groove knife, following knife point is the center of circle, suitable
Clockwise increases angle of the v-groove pre-compensation value, askew with the groove for improving the short groove for getting out, and both ensure product quality so as to reach, and
The purpose of energy improve production efficiency.
It should be appreciated that the application of the present invention is not limited to above-mentioned citing, and for those of ordinary skills, can
To be improved according to the above description or be converted, all these modifications and variations should all belong to the guarantor of claims of the present invention
Shield scope.
