Based on this, it is necessary to aiming at the problem that machined burrs, a kind of processing structure of non-metallic half bore of wiring board is provided,
It can conveniently process carrot-free non-metallic half bore.
A kind of processing structure of the non-metallic half bore of wiring board, the processing structure packet of the non-metallic half bore of the wiring board
Rubbing board ontology, the plate ontology are equipped with default slot and preset non-metallic hole, the length direction of the default slot with it is described non-
The processing line of plated through-hole is consistent, and the first end of the default slot is located at the outside in the non-metallic hole, the default slot
Second end is located at the inside in the non-metallic hole.
In machining of non-metallic half bore in the processing structure of the non-metallic half bore of above-mentioned wiring board, cutter is along nonmetallic
Change the processing line direction processing in hole, cutter is introduced into the first end of default slot, then the second end by presetting slot directly reach it is non-
The inside of plated through-hole.Therefore, the cutting point of cutter default slot first end, rather than on the side wall in non-metallic hole,
It avoids the cutting force of cutter from pullling the side wall in non-metallic hole, avoids the non-metallic half bore band processed jagged.That is, above-mentioned
The processing structure of the non-metallic half bore of wiring board can conveniently process carrot-free non-metallic half bore.
The side cell wall of the default slot is bonded with the processing line in the non-metallic hole in one of the embodiments,.
It is 3mil~4mil that the default slot, which protrudes into the length in the non-metallic hole, in one of the embodiments,.

Specific embodiment
The utility model is more fully retouched below with reference to relevant drawings for the ease of understanding the utility model,
It states.The better embodiment of the utility model is given in attached drawing.But the utility model can come in many different forms
It realizes, however it is not limited to embodiments described herein.On the contrary, the purpose of providing these embodiments is that making practical new to this
The disclosure of type understands more thorough and comprehensive.
In conjunction with Fig. 1, a kind of processing structure of the non-metallic half bore of wiring board, the non-metallic half bore of the wiring board adds
Work structure includes plate ontology, and the plate ontology is equipped with default slot and preset non-metallic hole, the length direction of the default slot
It is consistent with the processing line in the non-metallic hole.It should be noted that the length direction for " substantially " referring to default slot herein with
The processing line in the non-metallic hole is parallel or less parallel.For example, the length direction of default slot and the non-metallic hole
Angle between processing line is between -5 °~+5 °.Dotted line in Fig. 1 indicates the processing line in non-metallic hole, the arrow table of dotted line
Show the machine direction of cutter.The first end of the default slot is located at the outside in the non-metallic hole, and the second of the default slot
End is located at the inside in the non-metallic hole.
Fig. 2 is referred to, in machining of non-metallic half bore in the processing structure of the non-metallic half bore of above-mentioned wiring board, cutter
It is processed along the processing line direction in non-metallic hole, cutter is introduced into the first end of default slot, then the second end by presetting slot
Directly reach the inside in non-metallic hole.Since the cutting point of cutter is in the first end for presetting slot, rather than in non-metallic hole
Side wall on, so the cutting force of cutter is avoided that the side wall for pullling non-metallic hole, avoid the non-metallic half bore processed
With jagged.Therefore, the processing structure of the non-metallic half bore of above-mentioned wiring board can be processed conveniently carrot-free non-metallic
Half bore.
Wherein, milling cutter, lathe tool or other common process tools can be selected in cutter.For example, the non-metallic half bore of wiring board
Processing flow are as follows: in conjunction with Fig. 2, first, non-metallic hole, such as circular hole are drilled out on plate ontology；Second, it is drilled out on plate ontology
Default slot；Third is cut using milling cutter along the processing line in non-metallic hole.Finally, after milling cutter is processed, on plate ontology
Obtain non-metallic half bore.
And traditional non-metallic half bore processing flow are as follows: in conjunction with Fig. 3, due to plate ontology Non-precondition slot, with milling cutter plus
When the non-metallic half bore of work, milling cutter runs at high speed clockwise, and advances along the processing line in non-metallic hole.Milling cutter has just enter into non-gold
When categoryization hole, substrate is pullled by milling cutter cutting force, is easy to form burr (see Fig. 3) in non-metallic hole front end, and milling cutter
When by non-metallic hole rear end, therefore the non-metallic not formed burr in hole rear end can be arranged in the front end in non-metallic hole
Default slot in communication, for alleviating pullling for cutting force.
Fig. 1, the processing of the side cell wall of the default slot and the non-metallic hole are combined in one of the embodiments,
Line fitting, then cutter marches at default slot along processing line, and the resistance being subject to is small, avoids pullling plate ontology and causes burr.
Specifically, the default slot protrudes into the length in the non-metallic hole and is.The length of 3mil~4mil can guarantee knife
Tool stably enters in non-metallic hole.
Wherein, the length of the default slot is 1.2mm~1.6mm, and the width of the default slot is 0.6mm~0.8mm.It is wide
Degree can accommodate cutter, can be less than the radius in non-metallic hole, save the processing cost of default slot.The length of default slot
It is suitable with width, convenient for the smooth change of Tool in Cutting power.The both ends of the default slot are equipped with arc-shaped edges, convenient for the cutting of cutter
Power smooth change will not generate mutation.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
