Abstract
The invention relates to a board grinding method for removing orifice burrs of a printed circuit board (PCB). The method comprises the following steps of: 1, providing a board grinding machine and a drilled PCB, wherein the board grinding machine comprises a pair of upper grinding wheels and a pair of lower grinding wheels, and two grinding wheels of each pair are respectively provided with grinding brushes; and 2, grinding the PCB which is positioned between the two pairs of upper and lower grinding wheels, and respectively grinding the upper and lower sides of the PCB by the grinding brushes of the two pairs of upper and lower grinding wheels to remove the drilled orifice burrs, wherein the rotating directions of the two grinding wheels of each pair are opposite when the board is ground. According to the board grinding method for removing the orifice burrs of the PCB, because the positive and negative grinding wheels are adopted for grinding the board, the drilled orifice burrs can be effectively removed, and the grinding brushes can be effectively prevented from removing the bottom copper of the orifice in a single direction.
Description
Technical field
(Printed Circuit Board, PCB) making field relate in particular to the nog plate method that a kind of pcb board is removed the aperture burr to the present invention relates to printed circuit board (PCB).
Background technology
In the pcb board manufacturing process, the pcb board after the boring adopts polish-brush usually, is generally the pin brush, removes aperture burr and burr, but because the inherent characteristic of pin brush can be removed the aperture copper sheet simultaneously, causes the aperture not have copper-plated situation, thereby influence the reliability of pcb board.Therefore, this type of defective is needed improvement badly.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of pcb board to remove the nog plate method of aperture burr, through adopting positive and negative emery wheel, copper at the bottom of can effectively removing the aperture burr and can effectively avoiding polish-brush one-way removal aperture.
For realizing above-mentioned purpose, the present invention provides a kind of pcb board to remove the nog plate method of aperture burr, comprises the steps:
Step 1: provide Plate grinder and boring after pcb board, this Plate grinder comprises upper and lower two pairs of emery wheels, is respectively equipped with polish-brush on each two emery wheel to emery wheel;
Step 2: this pcb board is carried out nog plate; This pcb board is between these upper and lower two pairs of emery wheels; And respectively nog plate is carried out in the upper and lower both sides of this pcb board by the polish-brush of these upper and lower two pairs of emery wheels and handle; To remove the aperture burr of boring, during nog plate, each is opposite to the direction of rotation of two emery wheels of emery wheel.
Wherein, the parallelogram setting that interlocks of upper and lower two pairs of emery wheels of this Plate grinder, during nog plate, the direction of rotation that is two emery wheels that the diagonal angle is provided with in these upper and lower two pairs of emery wheels is identical.
Wherein, the parallelogram setting that interlocks of upper and lower two pairs of emery wheels of this Plate grinder, during nog plate, the direction of rotation that is two emery wheels that the diagonal angle is provided with in these upper and lower two pairs of emery wheels is opposite.
Beneficial effect of the present invention: pcb board of the present invention is removed the nog plate method of aperture burr; Through adopting upper and lower two pairs of emery wheels to come nog plate is carried out in the upper and lower both sides of pcb board; And during nog plate, each is opposite to the direction of rotation of two emery wheels of emery wheel, adopts this kind nog plate method; Can effectively remove the aperture burr of boring, and can effectively avoid the polish-brush one-way to remove copper at the bottom of the aperture.
For further setting forth technological means and the effect that the present invention takes for the predetermined purpose of realization; See also following about detailed description of the present invention and accompanying drawing; Believe the object of the invention, characteristic and characteristics; Should obtain thus going deep into and concrete understanding, yet accompanying drawing only provides reference and explanation usefulness, is not to be used for the present invention is limited.
Description of drawings
Below in conjunction with accompanying drawing, describe in detail through specific embodiments of the invention, will make technical scheme of the present invention and other beneficial effects obvious.
In the accompanying drawing,
Fig. 1 removes the sketch map of nog plate method one preferred embodiment of aperture burr for pcb board of the present invention;
Fig. 2 removes the sketch map of another preferred embodiment of nog plate method of aperture burr for pcb board of the present invention.
The specific embodiment
As shown in Figure 1, remove the sketch map of nog plate method one preferred embodiment of aperture burr for pcb board of the present invention.
This pcb board is removed the nog plate method of aperture burr, comprises the steps:
Step 1: provide Plate grinder and boring after pcb board 10, this Plate grinder comprises upper and lower two pairs of emery wheels 20, is respectively equipped with polish-brush on each two emery wheel 21 to emery wheel 20;
Step 2: this pcb board 10 is carried out nog plate; This pcb board 10 is between these upper and lower two pairs of emery wheels 20; And respectively nog plate is carried out in the upper and lower both sides of this pcb board 10 by the polish-brush of these upper and lower two pairs of emery wheels 20 and handle; To remove the aperture burr of boring, during nog plate, each is opposite to the direction of rotation of two emery wheels 21 of emery wheel 20.
In the present embodiment, the 20 staggered parallelogram settings of upper and lower two pairs of emery wheels of this Plate grinder, during nog plate, the direction of rotation that is two emery wheels 21 that the diagonal angle is provided with in these upper and lower two pairs of emery wheels 20 is identical.Wherein two inboards two emery wheels 21 being the diagonal angle setting are rotated in a clockwise direction, and two outsides are two emery wheels 21 that the diagonal angle is provided with along rotation counterclockwise.In other embodiments, the direction of rotation of these upper and lower two pairs of emery wheels 20 also can be other forms.
Be illustrated in figure 2 as pcb board of the present invention and remove the sketch map of another preferred embodiment of nog plate method of aperture burr.In this embodiment; Each direction of rotation to two emery wheels 21 of emery wheel 20 is opposite equally; Upper and lower two pairs of emery wheels 20 same staggered parallelogram settings of Plate grinder; Difference is, when pcb board 10 was carried out nog plate, the direction of rotation that is two emery wheels 21 that the diagonal angle is provided with in these upper and lower two pairs of emery wheels 20 was opposite.
Above-mentioned pcb board is removed the nog plate method of aperture burr; Through adopting upper and lower two pairs of emery wheels to come nog plate is carried out in the upper and lower both sides of pcb board; And during nog plate, each is opposite to the direction of rotation of two emery wheels of emery wheel, adopts this kind nog plate method; Can effectively remove the aperture burr of boring, and can effectively avoid the polish-brush one-way to remove copper at the bottom of the aperture.
The above; For the person of ordinary skill of the art; Can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the protection domain of accompanying Claim of the present invention.
