Description
Technical field
The present invention relates to a kind of punching alignment target method for designing being applied to multi-layer sheet wiring board.
Background technology
With electronic product to miniaturization, multifunction and high integration development, multi-layer sheet early becomes wiring board
Main flow.Multi-layer sheet number of plies more and more higher, wiring density is increasing, the requirement also more and more higher to interlayer alignment precision.Multilamellar
Plate is formed by the pressing of multiple core materials, and core material is designed with conductor fig, and core material is all using first punching, Ran Houyong
Hole punched para-position, is bound or riveted etc., to be ensured the aligning accuracy of interlayer conductor fig.Therefore, the precision of punching is to
Whole interlayer alignment precision impact is very big.Perforating press is to capture punching alignment target using CCD camera lens, and adjust automatically internal layer core
Plate placement location, to ensure punching precision.For ensureing the accuracy of CCD grabbing graphics, the position of perforating press CCD camera lens can only be done
Fixed position is moved.
As shown in figure 1, in current industry, for the punching of core material, all using design punching pair on the internal layer film
Bit pattern, then transfers to the figure on the film on core material, is punched out further according to aligning graph.Due to core material
Size can change after laminating, and the central layer change in size of different-thickness is variant, not lose for guarantee finished product board size
Very, internal layer film figure can carry out pre- harmomegathus, and that is, inner figure is not 1:1.Two problems thus can be brought：
(1) because CCD distance of camera lens is 1:1, punching alignment target and CCD camera lens not in same upright position, to CCD mirror
The accuracy of head grabbing graphics has certain impact, and then affects punching precision.
(2) punching target patterns are not 1:1, and the multi-layer sheet perforating press using in industry is 1:1 punching, leads to go out
The hole relative graphical coming can occur certain deviation, due to punching board it some times happens that punching off normal, bad during hand inspection sentences
This skew disconnected is normal phenomenon or punching precision is problematic.
Content of the invention
Based on this, the invention reside in overcoming the defect of prior art, provide a kind of method for designing of punching alignment target, should
Method for designing is conducive to improving punching precision.
Its technical scheme is as follows：
A kind of method for designing of punching alignment target, comprises the following steps：
Design first original circuit distribution pattern on computers, this first original circuit distribution pattern includes punching alignment target figure
Shape；
Former graphics proportion is kept to the part of punching consistent alignment target figure in first original circuit distribution pattern, to this routing layout
The remainder of figure carries out harmomegathus, obtains harmomegathus circuit distribution pattern；
Harmomegathus circuit distribution pattern is transferred on the film, obtains film figure.
Further, described harmomegathus has a corresponding harmomegathus value, the scope of this harmomegathus value be more than 0.997 and less than 1 or
More than 1 and less than 1.003.
Further, when designing first original circuit distribution pattern on computers, first original circuit distribution pattern and reality are made
The ratio of circuit distribution pattern is 1:1.
Below the advantage or principle of preceding solution is illustrated：
1st, perforating press, when being punched out to core material, is to arrest punching para-position target by CCD camera lens, and then accurately
Determine punching position.Because CCD distance of camera lens is with 1:1 carries out figure arrests, then by not carrying out to punching consistent alignment target figure
Harmomegathus is it can be ensured that the line at the center of the center of CCD camera lens and corresponding punching alignment target, perpendicular to core material, makes CCD
Camera lens can more be accurately aligned with corresponding punching alignment target and be arrested with carrying out figure, and then in perforating press with 1:1 is carried out
It can be ensured that the precision of punching in the case of punching.Therefore the method for designing of described punching alignment target is conducive to improving punching
Precision.
2nd, because punching occurs off normal relevant with punching consistent alignment target figure, in some cases also with punching machine punch certainly
Body is relevant, thus, after the method for designing using described punching alignment target, if punching deviation problem still occurs, can be determined that
Possibly there is perforating press itself punching to cause, thus can judge punching precision problem or normal phenomenon, thus favorably
In carrying out improvement problem.Therefore, can intuitively confirm whether board punching precision is abnormal by this method for designing and corresponding construction,
Avoid every time checking punching precision with special inspecting equipment, can improve production efficiency, and equipment testing cost can be saved.
3rd, the scope of described harmomegathus value is more than 0.997 and less than 1 or more than 1 and is less than 1.003, then it can be avoided that internal layer
The finished product board size problem of dtmf distortion DTMF that central layer causes because of change in size after laminating, and then it is advantageously ensured that the quality of production board.
4th, when designing first original circuit distribution pattern on computers, first original circuit distribution pattern is made to be distributed with actual track
The ratio of figure is 1:1, then ensure that the actual track distribution of wiring board can be consistent with first original circuit distribution pattern or basic
Unanimously.
5th, after obtaining described film figure, by this film figure with 1:1 ratio is transferred on core material, then punching
Machine can be punched out according to this film figure, in addition, enterprising in core material also according to this film figure in subsequent handling
The making of row line.
6th, the method for designing of described punching alignment target does not increase flow process and production cost.
