Description
Technical field
The present invention relates to PCB production fields, and in particular to a kind of method of anti-dust suction blockage in copper base boring procedure.
Background technology
With the development of electronics industry, the development of PCB is with reforming also in change slowly, especially China's Mainland
On pcb board accounting it is increasing, while daily necessities, science and technology, automobile industry high speed development drive on, PCB
As the carrier of electronic product, also constantly it can update and change, such as：Copper base, one kind is applied to high-frequency circuit and height
In the radiating and architectural decoration of the regional and accurate communication equipment of low temperature change greatly, thicker copper foil plus metal is it used
Basal plate is combined, and copper base metal-based layer is the supporting member of copper base, it is desirable to high-termal conductivity, usually copper coin, Gu
Many challenges are brought in drilling production difficulty, especially producing copper base process needs to bore the different hole of various sizes and a large amount of anti-
Blast hole（For mitigating the hole of impulsive force during mould punching in PCB productions）, due to adopting when usual copper-based twist drill macropore and explosionproof hole
Nozzle is bored with large scale disposably to drill, and a large amount of block dust and copper wire that produce can cause dust suction blockage, this research master
To be improved around a kind of anti-sweep-up pipe obstruction method research of boring procedure with reference to actual producing line condition, it is ensured that production is smooth.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of method of anti-dust suction blockage in copper base boring procedure.
The technical problems to be solved by the invention are achieved by the following technical programs：
The method of anti-dust suction blockage, comprises the following steps in a kind of copper base boring procedure：
（1）Improve drilling:When carrying out the drilling design of copper base drilling, the macropore of all diameter >=3.0mm in drilling is chosen,
Design four apertures in macroporous regions, four apertures and macropore is tangent and four apertures between adjacent two apertures
Distance >=0.1mm；The explosionproof hole of all a diameter of 1.4-3.0mm in drilling is chosen, a mesopore is designed in explosion-proof bore region,
The mesopore not with explosionproof hole is tangent and area is more than the half of explosionproof hole；
（2）Improve copper base drilling program:When being drilled to copper base, macropore and explosionproof hole are bored after subdrilling aperture and mesopore again, it is right
The side that nozzle stops one turn of switching using multistage drilling program one is bored using segmentation driller's skill, i.e. setting in all diameter ＞ 1.8mm hole
Formula drills.
Further, described multistage drilling program is four sections of drilling programs, i.e., to stop, drilling, stop, drilling, stop
Only, drill, stop, the mode of drilling manipulates brill nozzle.
The present invention has the advantages that：
This method subdrilling aperture and mesopore then bore macropore and explosionproof hole again, and the small size that middle aperture is used bores nozzle can effectively chip
Base material further reduces the block dust for boring and being produced during macropore without forming block, then, while using segmentation driller's skill, can
Incision copper wire, which is not formed, twines silk.Load forces and the master of sweep-up pipe are effectively reduced due to not producing a large amount of copper wires, block dust
Axle torsion, also ensures the smooth of dust sucting pipeline, maintains board production stability, it is to avoid deadlock, maintenance of equipment cost.
Embodiment
With reference to embodiment, the present invention will be described in detail, and embodiment is only the preferred embodiment of the present invention,
It is not limitation of the invention.
The method of anti-dust suction blockage, comprises the following steps in a kind of copper base boring procedure：
（1）Improve drilling:When carrying out the drilling design of copper base drilling, the macropore of all diameter >=3.0mm in drilling is chosen,
Design four apertures in macroporous regions, four apertures and macropore is tangent and four apertures between adjacent two apertures
Distance >=0.1mm；The explosionproof hole of all a diameter of 1.4-3.0mm in drilling is chosen, a mesopore is designed in explosion-proof bore region,
The mesopore not with explosionproof hole is tangent and area is more than the half of explosionproof hole；
（2）Improve copper base drilling program:When being drilled to copper base, macropore and explosionproof hole are bored after subdrilling aperture and mesopore again, it is right
The side that nozzle stops one turn of switching using multistage drilling program one is bored using segmentation driller's skill, i.e. setting in all diameter ＞ 1.8mm hole
Formula drills.I.e. with stop, drilling, stop, drilling, stop, drilling, stop, drilling four sections of drilling program modes manipulate brill nozzle.
I takes charge of the area of copper base, power supply with a large amount of explosion-proof orifice plates and monthly accounts for 1.5% at present, is bored by using this one kind
The anti-sweep-up pipe obstruction method of hole process, it is to avoid deadlock, maintenance of equipment cost, its explosion-proof orifice plate lamination number adds 1PNL, is taken charge of by me
Drill the monthly Wan ㎡ of output 9, and synthesis can save 800,000 yuans every year.
