Abstract
The present invention provides a kind of pcb board prebored hole method for overcoming harmomegathus problem, including step in detail below：S1. to two 2.0mm bullports of subdrilling in groove before being bored one, then bore nozzle using 0.8mm in R Angle Positions again and carry out 4 expansion punchings of preboring, the unnecessary position in its R angle is removed；S2. bore nozzle using 0.8mm at slotted eye edge to bore by unnecessary R angle parts, after preboring, R angular zones are eliminated.The present invention solves pcb board because of heavy copper milling plate after plate face harmomegathus, and caused because harmomegathus deviation, groove milling hole off normal causes justifying to be scrapped；Because harmomegathus deviation, there is difference with component pins in groove milling size, causes plug-in unit bad, difficult；Because the heavy copper groove technique of one milling of increase causes cost to increase, operating efficiency reduces, cost wastes；Because of carrying, number of turnover increase, plate face wipes the problem of spending probability increase.
Description
Technical field
A kind of designed lines plate processing technique field of the present invention, and in particular to pcb board prebored hole side for overcoming harmomegathus problem
Method.
Background technology
In the processing of existing pcb board, the slotted eye for installing electronic component is used on pcb board, client to need to element
There are more strict requirements at insertion slotted eye R angles（In SMT, component part pin is fully met in insertion slotted eye, to meet client's need
Ask, handled by the way of copper is sunk in milling）It is to sink an increased technique stream outside copper forehead after the brill of plank one that copper groove is sunk in milling
Journey.
In addition, simple one mode bored substitutes the heavy copper groove of milling, and because groove width is larger, the same mistake of bore of the brill nozzle used
Greatly, it is equally big by R angles caused by drill flute pit bore edges, often cause component part pin insertion slotted eye difficult, or even go out
Existing element can not get through.
It is badly in need of a kind of processing method and overcomes above mentioned problem.
The content of the invention
In view of this, the present invention provides a kind of pcb board prebored hole method that can overcome harmomegathus problem, and the present invention solves
Pcb board is because of heavy copper milling plate after plate face harmomegathus, and caused because harmomegathus deviation, groove milling hole off normal causes justifying to be scrapped；Because harmomegathus
There is difference with component pins, cause plug-in unit bad, difficult in deviation, groove milling size；Because the heavy copper groove technique of one milling of increase causes into
This increase, operating efficiency reduces, cost wastes；Because of carrying, number of turnover increase, plate face wipes the problem of spending probability increase.
The technical scheme is that：
A kind of pcb board prebored hole method that can overcome harmomegathus problem：Including step in detail below：
S1. it is then pre- using 0.8mm brill nozzle progress in R Angle Positions again to two 2.0mm bullports of subdrilling in groove before being bored one
4 expansion punchings are bored, the unnecessary position in its R angle is removed；
S2. bore nozzle using 0.8mm at slotted eye edge to bore by unnecessary R angle parts, after preboring, R angular zones are eliminated.
Further, in step S1, specific processing mode is：Two hole A of subdrilling 2.0mm, then bore 0.8mm 4 expansion punchings
Hole B, 2.4mm hole C is then bored, complete whole slotted eye shaping.
Actual slotted eye R angles redundance is cleaned after one bores improvement, both can guarantee that the smooth insertion of vigour part part pin, together
When process for copper is sunk into milling remove to be bored by one and substitute, reduce flow time and cost and waste producing.
The beneficial effects of the present invention are solve pcb board because of heavy copper milling plate, caused series of problems after plate face harmomegathus：
Because harmomegathus deviation, groove milling hole off normal causes justifying to be scrapped；Because harmomegathus deviation, there is difference with component pins in groove milling size, leads
Cause plug-in unit bad, difficult；Because the heavy copper groove technique of one milling of increase causes cost to increase, operating efficiency reduces, cost wastes；Because removing
Fortune, number of turnover increase, plate face wipe flower probability increase.
Brief description of the drawings
Fig. 1 is the processing hole arrangement schematic diagram of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Embodiment 1
A kind of pcb board prebored hole method that can overcome harmomegathus problem：Including step in detail below：
S1. it is then pre- using 0.8mm brill nozzle progress in R Angle Positions again to two 2.0mm bullports of subdrilling in groove before being bored one
4 expansion punchings are bored, the unnecessary position in its R angle is removed；
S2. bore nozzle using 0.8mm at slotted eye edge to bore by unnecessary R angle parts, after preboring, R angular zones are eliminated.
Further, in step S1, specific processing mode is：Two hole A 1 of subdrilling 2.0mm, then bore 0.8mm 4 expansions
Punching B 2,2.4mm hole C 3 is then bored, complete whole slotted eye shaping.
Actual slotted eye R angles redundance is cleaned after one bores improvement, both can guarantee that the smooth insertion of vigour part part pin, together
When process for copper is sunk into milling remove to be bored by one and substitute, reduce flow time and cost and waste producing.
The beneficial effects of the present invention are solve pcb board because of heavy copper milling plate, caused series of problems after plate face harmomegathus：
Because harmomegathus deviation, groove milling hole off normal causes justifying to be scrapped；Because harmomegathus deviation, there is difference with component pins in groove milling size, leads
Cause plug-in unit bad, difficult；Because the heavy copper groove technique of one milling of increase causes cost to increase, operating efficiency reduces, cost wastes；Because removing
Fortune, number of turnover increase, plate face wipe flower probability increase.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
