The invention belongs to a processing method for a circuit board provided with slots and platforms. The method is characterized by the following steps: a) selecting a CNC milling machine whose spindle clamping force is greater than or equal to 350 N, whose spindle radial jump is smaller than or equal to 20 micrometers and whose perpendicularity between the spindle and the table face is smaller than or equal to 50 micrometers; b) placing an auxiliary base plate on the table face of the CNC milling machine; c) placing a three-blade milling cutter (5) with an SHC coating on the main shaft of the CNC milling machine; d) setting a milling program; e) selecting cutting points of the three-blade milling cutter (5); f) setting the feed amount of the main shaft of the milling machine, wherein the rotation speed is controlled at 40+10 krpm and the feed amount is controlled within 80-120 ipm. By adopting the method for processing the circuit board provided with the slots and the platforms, the combination strength of a copper coating on a hole wall and the hole wall can be ensured and no separation may be caused. The quality is good and the efficiency is high.
Description
Technical field
The invention belongs to the processing method of wiring board, particularly a kind of processing method being provided with slotted eye, plane line plate.
Background technology
Along with the development of society, electronic product is also day by day to little, thin, smart future development.So so just bring sizable challenge to the design of pcb board.In a lot of exquisiter electronic product, client does not have too many space to place components and parts in design, just needs to accomplish to place with limited space the components and parts being greater than spatial dimension, and this point impossible is accomplished in prior art processing routinely.We are by being exactly popularization degree and the effect of wanting larger production to the technical research of this project, to obtain larger economic results in society.
Be provided with the wiring board of wiring board as a kind of special construction of slotted eye platform, in fact be exactly on the basis of copper-plated hole or groove, tack counterbore or a deep gouge is processed by the method for brill or milling, be used for installing device, lay the production plate surface requirements after components and parts smooth, smooth, without protruding, be equivalent to like this expand and produce plate usable floor area, but, in actual production process, have the bad solution always of two problems: the guarantee problem being first the adhesion intensity between hole wall copper facing and hole wall; Secondly, the hole wall separation problem produced in milling process, particularly hole wall separation problem, this is definitely unallowed, and this problem also troubles technical research personnel always for a long time, does not obtain basic effective solution all the time.
Summary of the invention
The object of the invention is to overcome above technical deficiency, a kind of adhesion intensity ensured between hole wall copper facing and hole wall is provided, hole wall copper facing and the unseparated processing method being provided with slotted eye, plane line plate of hole wall.
The technical scheme that technical solution problem of the present invention adopts is: a kind of processing method being provided with slotted eye, plane line plate, and its feature takes following steps: a. selects the CNC milling machine of the perpendicularity≤50um of main shaft claming power >=350N, main shaft diameter jumping≤20um, main shaft and table top; B. on the table top of CNC milling machine, put a subbolster, with pin, wiring board is fixed on subbolster; A 1.0mm thickness epoxy resin cover plate is fixed in face in the circuit board; C. on the main shaft of CNC milling machine, lay three blade milling cutters of a SHC coating, tool geometry angle meets Technical specifications; D. set milling program: milling machine spindle is rotated forward, and processes by upmilling mode, namely milling machine spindle is contrary with the wiring board direction of motion, three blade milling cutters are by tool feeding horizontal direction F1 and tool feeding vertical direction F2 direction feeding; E. selected 3 blade milling cutter roll setting points: the axle center of three blade milling cutters be made to avoid the copper-plated distance lambda of slotted eye wall, λ=0.50 ~ 1.20mm; F. the milling machine spindle amount of feeding is set: rotating speed controls at 40 ± 10krpm, and the amount of feeding controls at 80 ~ 120ipm.
The invention has the beneficial effects as follows: adopt the method to being provided with slotted eye, plane line plate is processed, and ensure that the intensity of adhesion between hole wall copper facing and hole wall, can not produce separation, quality is good, and efficiency is high.

In figure: 1-wiring board; 2-deep gouge side; 3-deep gouge shoulder; The copper facing of 4-slotted eye wall; 5-tri-sword milling sword; λ-three blade milling cutter and the copper-plated distance of slotted eye wall; F1-tool feeding horizontal direction; F2-tool feeding vertical direction.
Embodiment
Embodiment, with reference to accompanying drawing, a kind of processing method being provided with slotted eye, plane line plate, its feature takes following steps: a. selects the CNC milling machine of the perpendicularity≤50um of main shaft claming power >=350N, main shaft diameter jumping≤20um, main shaft and table top; B. on the table top of CNC milling machine, put a subbolster, with pin, wiring board 1 is fixed on subbolster; A 1.0mm thickness epoxy resin cover plate is fixed on wiring board 1; C. on the main shaft of CNC milling machine, lay three blade milling cutters 5 of a SHC coating, tool geometry angle meets Technical specifications; D. set milling program: milling machine spindle is rotated forward, and processes by upmilling mode, namely milling machine spindle is contrary with wiring board 1 direction of motion, three blade milling cutters 5 are by tool feeding horizontal direction F1 and tool feeding vertical direction F2 direction feeding; E. selected 3 blade milling cutter 5 roll setting points: the axle center of three blade milling cutters 5 be made to avoid the distance lambda of slotted eye wall copper facing 4, λ=0.50 ~ 1.20mm; F. the milling machine spindle amount of feeding is set: rotating speed controls at 40 ± 10krpm, and the amount of feeding controls at 80 ~ 120ipm.
The center of wiring board 1 will process an oval elongated hole, is used for installing electrical equipment original paper.Lower end, deep gouge side 2 in hole is provided with deep gouge shoulder 3; Hole wall below deep gouge shoulder 3 is coated with slotted eye wall copper facing 4.
Add man-hour, three blade milling cutter 5 traverse feeds, namely move with milling machine spindle to the vertical direction of track, feed toward interior principle by from outer, input should be increased as far as possible, make cutting force continuous, avoids producing alternate stress, is conducive to formation and the eliminating of metal fillings.
This invention adapts to the circuit board processing that slotted eye wall coating thickness is not less than 25um especially; If coating is excessively thin, carry out the adjustment of parameter, basic skills is constant.
