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, relate in particular to a kind of for improving pcb board preparation method and the pcb board that short groove groove is askew.
Background technology
In prior art, the short groove processing method of pcb board is generally first to add drill hole at groove two ends at present, re-use groove cutter and get out short groove, but process by this method short groove, for the short groove of flute length≤2 times groove width, can produce groove askew, when production, can only carry out management and control by reducing folded number, cannot thoroughly improve the askew phenomenon of short groove groove, and reduce production efficiency.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind ofly for improving pcb board preparation method and the pcb board that short groove groove is askew, be intended to solve the short groove processing method of existing pcb board and cannot improve the askew problem of short groove groove.
Technical scheme of the present invention is as follows:
For improving the pcb board preparation method that short groove groove is askew, wherein, comprise step:
In the time using groove cutter to carry out drill flute, below cutter point be the center of circle, clockwise direction increases angle of the v-groove pre-compensation value, askew to improve the groove of the short groove getting out.
Described for improving the pcb board preparation method that short groove groove is askew, wherein, flute length≤2 of described short groove times groove width.
Described for improving the pcb board preparation method that short groove groove is askew, wherein, angle of the v-groove pre-compensation value is 3 ~ 5 degree.
Described for improving the pcb board preparation method that short groove groove is askew, wherein, angle of the v-groove pre-compensation value is 4 degree.
Described for improving the pcb board preparation method that short groove groove is askew, wherein, use groove cutter to get out short groove by G85 instruction.
A kind of pcb board, is characterized in that, adopts preparation method as above to make.
Beneficial effect: pcb board preparation method of the present invention, in the time using groove cutter to carry out drill flute, below cutter point be the center of circle, increase clockwise angle of the v-groove pre-compensation value, the groove of the short groove getting out with improvement is askew, both ensures product quality, the object that can enhance productivity again thereby reached.。
Brief description of the drawings
Fig. 1 is the structural representation of the short-and-medium groove of prior art processing while occurring that groove is askew.
Fig. 2 is at the structural representation adding while compensating man-hour in the present invention.
Detailed description of the invention
The invention provides a kind ofly for improving pcb board preparation method and the pcb board that short groove groove is askew, for making object of the present invention, technical scheme and effect clearer, clear and definite, below the present invention is described in more detail.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Provided by the present invention a kind of for improving the pcb board preparation method preferred embodiment that short groove groove is askew, it comprises step:
In the time using groove cutter to carry out drill flute, below cutter point be the center of circle, clockwise direction increases angle of the v-groove pre-compensation value, askew to improve the groove of the short groove getting out.
As shown in Figure 1, adopting conventional method to add man-hour, below cutter point 100 be the center of circle, short groove is upper distortion counterclockwise, and conventional method can only count the askew problem of management and control groove by reducing to fold.As shown in Figure 2, the present invention is the center of circle by following cutter point 100, increases clockwise an angle of the v-groove pre-compensation value, thereby offsets with the angle of counterclockwise upper distortion, has thoroughly solved the askew problem of groove.
In the time that drilling is made, taking the lower cutter point 100 of groove cutter as the center of circle, increase clockwise angle of the v-groove pre-compensation value, and without drill hole, so both accomplished to improve the problem that short groove occurs that groove is askew, carry out management and control without reducing folded number again, so improved production efficiency, ensured again product quality.
Further, flute length≤2 of described short groove times groove width, supposes that groove width is s, and flute length should be less than 2s, and method of the present invention 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.Further, while using groove cutter, get out short groove by G85 instruction.
Hard lead and chew every brill 2.0mm thick plates for adding below Φ 1.5mm, deflection angle is 3 ~ 5 degree, and every amendment deflection 0.05mm is angle inclination 3 degree.
For example, can be amended as follows for the brill program of chewing of Φ 1.0mm:
XYG85X1.0Y0 is revised as: XYG851.0Y-0.05;
Or XYG85X0Y1.0 is revised as: XYG85X0.05Y1.0
In addition, also can coordinate the cutter speed that reduces groove cutter to solve the problem that groove is askew simultaneously,
In addition, also can increase prebored hole, for example groove width is 0.8mm, and before boring this groove, the hole of cutter point increase 0.4mm or 0.5mm under the groove cutter of two, plays guiding function respectively, need to be concentric circles, descending cutter point and prebored hole is the same center of circle.In addition, add and even more preferably use man-hour the long shorter slot brill of sword to chew.
Based on above-mentioned preparation method, the present invention also provides a kind of pcb board preferred embodiment, and it adopts preparation method as above to make.
In sum, pcb board preparation method of the present invention, in the time being used groove cutter to carry out drill flute, following cutter point is the center of circle, increases clockwise angle of the v-groove pre-compensation value, askew to improve the groove of the short groove getting out, both ensure product quality thereby reached, the object that can enhance productivity again.
Should be understood that, application of the present invention is not limited to above-mentioned giving an example, and for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
