Abstract
The utility model discloses a kind of hole machined structure of module pcb board half, include the pcb board of two pieces of docking, the half bore being wherein machined with pcb board between half bore, pcb board is adjacent just to docking, and using metallised conductors structure on the hole wall of the half bore of one of pcb board；Half bore is just to being drilled with the first drilling and the second drilling at adjacent half bore, the utility model is by the way of secondary drilling, there to be copper hole to be redrilled once, the hole of unnecessary half is allowed to break, unnecessary conductor is carried out stinging eating away by corroding liquid medicine, so as to reduce hidden danger during sharp processing process, prevent excess conductor residual and reduce pcb module short circuits and scrap generation.For present traditional processing mode, substantial amounts of residual copper wire is had in leg annex, so as to cause module short circuit, which reduces the ratio of short circuit after device has been welded, substantially increases the qualification rate of product, reduce waste.
Description
Technical field
The utility model is related to PCB manufacture fields, specifically a kind of hole machined structure of module pcb board half.
Background technology
PCB Chineses are printed circuit board, also known as printed substrate, are important electronic units, are electronic components
Supporter, be electronic component electrical connection carrier.Because it is made using electron printing, therefore it is referred to as " print
Brush " circuit board.
Existing pcb technology for processing semi-hole is easily caused unnecessary half in shaping and has copper wire residual, so that in pcb
Cause finished product short circuit occur during assembling, cause the whole of device to scrap.
Utility model content
The purpose of this utility model is to provide a kind of hole machined structure of module pcb board half, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical scheme：
A kind of hole machined structure of module pcb board half, includes the pcb board of two pieces of docking, and half is wherein machined with pcb board
Half bore between hole, pcb board is adjacent just to docking, and using metallised conductors knot on the hole wall of the half bore of one of pcb board
Structure；Half bore is abolished just to being drilled with the first drilling and the second drilling at adjacent half bore using the first drilling and the second drilling
The hole wall structure of the half bore, thus prevent metallized semi-pore just to half bore contain part conductor residual, so as to avoid appearance
The situation of short circuit.
It is used as further program of the utility model：It is tangent between first drilling and the second drilling to set.
It is used as the utility model further scheme：First drilling is identical with the diameter of the second drilling.
It is used as the utility model further scheme：The diameter of first drilling and the second drilling is more than the straight of half bore
Footpath.
Compared with prior art, the beneficial effects of the utility model are：The utility model, will by the way of secondary drilling
There is copper hole to be redrilled once, allow the hole of unnecessary half to break, unnecessary conductor is carried out stinging eating away by corroding liquid medicine, so as to subtract
Hidden danger during few sharp processing process, prevents excess conductor residual and reduces pcb module short circuits and scrap generation.For present biography
System processing mode, has substantial amounts of residual copper wire in leg annex, so as to cause module short circuit, which reduces device welding
The ratio of short circuit, substantially increases the qualification rate of product, reduces waste after complete.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the hole machined structure of module pcb board half of the utility model.
In figure：1- half bore, 2- first drills, 3- second drills, 4-PCB plates.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of hole machined structure of module pcb board half, including two pieces of docking
The half bore 1 being machined with pcb board 4, wherein pcb board 4 between half bore 1, pcb board 4 is adjacent just to docking, and one of PCB
Metallised conductors structure is used on the hole wall of the half bore 1 of plate 4；Half bore 1 just to be drilled with adjacent half bore 1 first drilling 2 and
Second drilling 3, abolishes the hole wall structure of the half bore 1, so as to prevent metallized semi-pore 1 using the first drilling 2 and the second drilling 3
Just to half bore 1 containing part conductor remain so that avoid occur short circuit situation.
It is tangent between the drilling 3 of first drilling 2 and second to set.
First drilling 2 is identical with the diameter of the second drilling 3.
The diameter of the drilling 3 of first drilling 2 and second is more than the diameter of half bore 1.
Operation principle of the present utility model is：By the way of secondary drilling, there will be copper hole to be redrilled once, allow unnecessary one
Half hole is broken, and unnecessary conductor is carried out stinging eating away by corroding liquid medicine, so that hidden danger when reducing sharp processing process, Du
Exhausted excess conductor remains and reduces pcb module short circuits and scrap generation.For present traditional processing mode, substantial amounts of residual is had
Copper wire is in leg annex, so as to cause module short circuit, the invention reduces the ratio of short circuit after device has been welded, substantially increased
The qualification rate of product, reduces waste.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
