Description
Technical field
It is more particularly to a kind of to be provided with slotted eye, the processing method of plane line plate the invention belongs to the processing method of wiring board.
Background technology
With the continuous development of society, electronic product also increasingly develops to small, thin, smart direction.So thus give pcb board
Design bring sizable challenge.In much exquisiter electronic product, client is in design without too many space
Place component, it is necessary to accomplish to place the component for being more than spatial dimension with limited space, routinely prior art is processed
It is that impossible accomplish this point.We are by seeking to the popularization degree and effect of larger production to this item purpose technical research, to obtain
Obtain bigger economic results in society.
Wiring board provided with slotted eye platform as a kind of wiring board of special construction, actually in copper-plated hole or
On the basis of groove, by boring or the method for milling processes a tack counterbore or deep gouge, for installing device, after laying component
Produce plate surface and require smooth, smooth, no projection, so equivalent to production plate usable floor area is expanded, still, in actual production
During have the bad solution always of two problems：It is the guarantee problem of the combination force intensity between hole wall copper facing and hole wall first；
Secondly, caused hole wall separation problem, particularly hole wall separation problem in milling process, this absolutely not allows, and this is asked
Topic also troubles technical research personnel for a long time always, does not obtain basic effective solution all the time.
The content of the invention
It is an object of the invention to overcome the technical deficiency of the above, there is provided a kind of knot ensured between hole wall copper facing and hole wall
Intensity with joint efforts, hole wall copper facing are unseparated provided with slotted eye, the processing method of plane line plate with hole wall.
The technical proposal for solving the technical problem of the invention is：It is a kind of to be provided with slotted eye, the processing side of plane line plate
Method, its feature take following steps：A. it is vertical with table top from main shaft claming power >=350N, main shaft diameter jump≤20um, main shaft
Degree≤50um CNC milling machine；B. a subbolster is put on the table top of CNC milling machine, is fixed on wiring board with pin auxiliary
Help on backing plate；A 1.0mm thickness epoxy resin cover plate is fixed above assist side；C. one is laid on the main shaft of CNC milling machine
Three blade milling cutters of branch SHC coatings, tool geometry angle meet Technical specifications；D. milling program is set：Milling machine spindle is rotated forward,
And processed by upmilling mode, i.e. milling machine spindle and the wiring board direction of motion is on the contrary, three blade milling cutters press tool feeding horizontal direction F1
Fed with tool feeding vertical direction F2 directions；E. 3 blade milling cutter roll setting points are selected：The axle center of three blade milling cutters is set to avoid slotted eye
The copper-plated distance lambda of wall, λ=0.50~1.20mm；F. the milling machine spindle amount of feeding is set：Rotating speed is controlled in 40 ± 10krpm, the amount of feeding
Control is in 80~120ipm.
The beneficial effects of the invention are as follows：Using this method to being processed provided with slotted eye, plane line plate, it is ensured that hole wall
The intensity of adhesion between copper facing and hole wall, separation will not be produced, quality is good, efficiency high.
