Description
Technical field
The present invention relates to wiring board production technical field more particularly to a kind of making sides improving minute grooves on wiring board
Method.
Background technology
Printed circuit board is also known as wiring board (PCB, Printed Circuit Board).The production of wiring board includes circuit
Two links of design and manufacture, the manufacture of wiring board are designed as foundation with the circuit of early period, and manufacturing process is generally as follows：By design
It is required that core material, which is cut into required size → pad pasting on core material →, in sawing sheet process uses internal layer film aligning
Exposure → development remove not by the film of photocuring with formed the layers of copper of non-envelope covering on inner figure → etching core material with
It forms internal layer circuit → taking off film → each core material is stacked and is formed as one by high-temperature laminating more by certain put in order
Laminate → make hole metallization → electric plating of whole board that layers of copper thickness be made in hole to reach design according to borehole data drill flute hole → electroless copper plating is wanted
→ making the outer-layer circuit be connected with internal layer on multilayer boards → is asked silk-screen solder mask and to pass through film aligning on multilayer boards
The rear processes such as exposed and developed making solder mask → surface treatment → molding, detection.
Wherein, it when boring the slot that four angles are fillet design on multilayer boards, especially bores for following process into small gold
It when the minute grooves of categoryization slot (PTH), is usually made using drill point or gong knife, in the production process, first uses drill point in slot
Four Angle Positions of position (on wiring board for makes the region for forming slot) drill out a pilot hole respectively, then proceed to use drill point or
Gong knife makes slot along the sideline of slot position.Since the position of the pilot hole when four Angle Positions make pilot hole will appear little deviation, draw
The deviation of hole site can cause the shape of made slot to deform, especially for small-sized minute grooves, even if micro-
Small deviation can also significantly affect the shape of slot, cause slot lopsided, and minute grooves are generally used for transmission microwave letter on wiring board
Number, the deformity of slot can make microwave signal occur exception in transmission process.
Invention content
Easily there is the problem of slot deformity for the existing minute grooves that make in the circuit board in the present invention, provides a kind of simple and practicable
Improvement wiring board minute grooves production method, the problem that can effectively prevent slot deformity occur.
To achieve the above object, the present invention uses following technical scheme.
The production method of minute grooves on a kind of improvement wiring board forms the region of slot and is known as on the wiring board for making
The quadrangle of slot position, the slot and slot position is fillet, is included the following steps：
S1, a pilot hole is bored respectively at four fillets of slot position using the first drill point.
Preferably, in step S1, when the slot becomes metallization slot for making, the slot compares the metallization slot,
The unilateral pre- big value of slot is equal to the metal layer thickness of metallization groove groove wall.
S2, respectively each pilot hole is continued to process using the first drill point, forms the fillet of slot at four fillets of slot position.
Preferably, in step S2, respectively each pilot hole is continued to process using the first drill point, fillet processing is bored on slot position
Hole, the center of circle in fillet processing hole and the straight line where the center of circle of corresponding pilot hole are parallel with the long side of slot position.
S3, it is drilled on slot position to produce the short side of slot using the first drill point, i.e. the bore path of the first drill point is edge
Slot position short side is drilled from one end of slot position short side to the other end of slot position short side.
S4, it is drilled on slot position to produce another short side of slot in a manner of step S3.
S5, the long side for producing slot along the long side milling of slot position using gong knife.
S6, another long side for producing slot along another long side milling of slot position using gong knife, to which slot be made.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is by making pilot hole, fillet processing hole and slot
Short side when drilled using identical the first drill point of drill point of diameter, and hole is processed using subdrilling fillet after drill hole
And the processing flow on milling flute length side again after processing groove short side, the straight of the accuracy of pilot hole and the short side of slot and long side can be improved
Degree and accuracy, the problem of to prevent the made slot with fillet design from deforming, especially for minute grooves
Processing, the precision of made minute grooves significantly improves, and the problem of slotless deformity occurs.Meanwhile the method for the present invention is simply easy
Row, and production process is easy to monitor.
