Abstract
The invention discloses a method for processing a short slotted hole in a printed circuit board. The method comprises the following steps: (1) respectively drilling two pilot holes in corresponding edges in the length direction of a short slotted hole to be formed, wherein the aperture of each pilot hole is (the length of the short slotted hole-0.3 mm)/2, and the distance between the center of each pilot hole and the corresponding edges in the length direction of the short slotted hole to be formed is (the radius of each pilot hole+0.05 mm); and (2) adopting a slot knife of which the width is consistent with that of the short slotted hole to be formed to perform superposed drilling from one end of the short slotted hole to be formed in the length direction to the other end to obtain a short slotted hole. According to the method for processing the short slotted hole in the printed circuit board, the pilot holes are pre-drilled, and then superposed drilling is performed from one end of the short slotted hole to be formed to the other end, so that outward deflection of the slot knife in the drilling process can be guaranteed, centering of a drill and uniform stress are ensured, the machining precision is improved, and the requirement for the tolerance of +/-0.05 mm of the product precision by a customer is satisfied.
Description
Technical field
The present invention relates to the processing method of the short slotted eye of a kind of printed circuit board.
Background technology
So-called short slotted eye, refer to the slotted eye for mounting related components on printed circuit board, its length and width is than < 2:1, when processing this groove, owing to cannot feel relieved when it is holed, discontinuity, its dimensional accuracy is difficult to ensure, especially our customer requirement tolerance ensures to accomplish for just more difficult during ± 0.05mm, and it is crooked to there will be pass.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides the processing method of the short slotted eye of a kind of printed circuit board, overcoming short slotted eye drill bit in process cannot feel relieved, unbalance stress, produce the adverse effect of distortion, improve the machining accuracy of boring, meet the demand of client to product.
The present invention in order to the technical scheme solving its technical problem and adopt is:
A processing method for the short slotted eye of printed circuit board, comprises the following steps:
1. in the corresponding edge of waiting out short slotted eye length direction, two bullports are bored respectively, the aperture of this bullport is (short slotted eye length-0.3mm)/2, and the center of this bullport respectively distance waits out that the distance of the corresponding edge of short slotted eye length direction is (radius+0.05mm of bullport);
2. adopting the groove cutter consistent with waiting out short slotted eye width to carry out folded boring from one end of the length direction of short slotted eye to the other end, obtaining short slotted eye.
As a further improvement on the present invention, described step 1. in, adopt bit drills bullport; Described step 2. in, adopt G85 mode groove cutter to carry out folded boring to short slotted eye.
As a further improvement on the present invention, described step 2. in, when groove cutter carries out folded boring to short slotted eye, the deformation trace line direction at this Cao Dao center is relative to the center line clockwise 8 ° of this short slotted eye length direction.
The invention has the beneficial effects as follows: the processing method of the short slotted eye of this printed circuit board adopts preboring bullport, and then bore from short slotted eye one end to another endlap, so namely, can ensure that groove cutter outwards offsets in boring procedure, ensure the centering of drill bit, make its uniform force, improve machining accuracy, meet client to the tolerance requirements of Product Precision at ± 0.05mm.
Detailed description of the invention
In conjunction with the embodiments; the present invention is elaborated; but protection scope of the present invention is not limited to following embodiment, the simple equivalence namely in every case done with the present patent application the scope of the claims and description changes and modifies, and all still belongs within patent covering scope of the present invention.
A processing method for the short slotted eye of printed circuit board, comprises the following steps:
1. in the corresponding edge of waiting out short slotted eye length direction, two bullports are bored respectively, the aperture of this bullport is (short slotted eye length-0.3mm)/2, and the center of this bullport respectively distance waits out that the distance of the corresponding edge of short slotted eye length direction is (radius+0.05mm of bullport);
2. adopting the groove cutter consistent with waiting out short slotted eye width to carry out folded boring from one end of the length direction of short slotted eye to the other end, obtaining short slotted eye.
Described step 1. in, adopt bit drills bullport; Described step 2. in, adopt G85 mode groove cutter to carry out folded boring to short slotted eye.
Described step 2. in, when groove cutter carries out folded boring to short slotted eye, the deformation trace line direction at this Cao Dao center is relative to the center line clockwise 8 ° of this short slotted eye length direction.
Thus, the processing method of the short slotted eye of this printed circuit board adopts preboring bullport, and then bore from short slotted eye one end to another endlap, so namely, can ensure that groove cutter outwards offsets in boring procedure, ensure the centering of drill bit, make its uniform force, improve machining accuracy, meet client to the tolerance requirements of Product Precision at ± 0.05mm.
