Specific orientation is operated with specific orientation construction, should not be understood as limitation of the invention with this.
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
The present embodiment provides a kind of inclined distance measurement methods in the hole of machine drilling, comprising the following steps:
S10: core plate 1 is provided.
Specifically, core plate 1 successively includes upper copper, substrate and lower copper foil from top to bottom.
S20: core plate 1 is etched.
Generally, it only needs to etch in upper copper and lower copper foil when traditional core plate 1 is etched required
Line pattern.In the present embodiment, when etching the line pattern of the core plate 1, synchronization is etched in logicalnot circuit graphics field
Several positioning copper rings 2.Preferably, the outer diameter of all positioning copper rings 2 is all the same, and the internal diameter of each positioning copper ring 2 is not
The internal diameter of equal and each positioning copper ring 2 is all larger than the outer diameter of drill bit.Preferably, positioning copper ring 2 can be located to be used as and determine
At the tabulare or rim charge of position.
S30: it drills to core plate 1.
Specifically, it in machine drilling, while drilling out the through holes such as mounting hole, insert hole or via hole, needs same
Step bores a location hole 3 in the corresponding position of each positioning copper ring 2.
S40: sentenced according to the distance between the inner circle 201 of each location hole 3 and positioning copper ring 2 corresponding with the location hole 3
Hole offset distance when disconnected machine drilling from.
Specifically, on the one hand, since positioning copper ring 2 etch together with line pattern and is obtained, so positioning copper ring 2 and
Positioning between line pattern is very accurate；On the other hand, location hole 3 is run through with mounting hole, insert hole or via hole etc.
Hole synchronous processing obtains, so the positioning between the through holes such as location hole 3 and mounting hole, insert hole or via hole is also very
Precisely.Therefore, by comparing the concentricity of location hole 3 and positioning copper ring 2, so that it may judge the hole location and line map of machine drilling
Deviation situation between shape.Further, the concentricity of location hole 3 and positioning copper ring 2 can be converted to location hole 3 and positioning again
The distance between the inner circle 201 of copper ring 2 difference.
Further, when in the inner circle 201 that location hole 3 is located at corresponding positioning copper ring 2 and location hole 3 and inner circle 201 not
When tangent, the hole offset distance of machine drilling is from the radial difference for being less than both inner circle 201 and drill；When location hole 3 with it is corresponding fixed
When 201 inscribe of inner circle of position copper ring 2, the hole offset distance of machine drilling is from the radial difference for being equal to both inner circle 201 and drill；Work as portion
Point or whole location hole 3 when falling on other than the inner circle 201 of corresponding positioning copper ring 2, the hole offset distance of machine drilling is interior from being greater than
Justify the radial difference of both 201 and drill.Preferably, judge for convenience, the axis of all positioning copper rings 2 is same flat
In face；The positioning copper ring 2 is arranged successively from small to large according to the size of internal diameter, the distance between adjacent positioning copper ring 2 phase
Deng, and the internal diameter difference between adjacent positioning copper ring 2 is equal.
Specifically, as long as observing the positional relationship between each location hole 3 and corresponding inner circle 201, so that it may which device to hole is inclined
Distance carries out a general judgement, simple and convenient without increasing measuring tool.For example, the radius of drill is 2mil；Position copper
There are five rings 2, and radius is followed successively by 3.5mil, 4mil, 4.5mil, 5mil, 5.5mil:
As shown in Figure 1, illustrating that this is each if each location hole 3 is respectively positioned in the inner circle 201 of corresponding positioning copper ring 2
The inclined situation in the hole of location hole 3 is successively: being not more than 1.5mil, is not more than 2mil, is not more than 2.5mil, is not more than 3mil, is little
In 3.5mil, to sum up, the hole offset distance of this machine drilling is from no more than 1.5mil；
As shown in Fig. 2, if first and second location hole 3 are partially or entirely located in corresponding positioning copper ring 2
Except inner circle 201,201 inscribe of inner circle of third location hole 3 and corresponding positioning copper ring 2, and the 4th and the 5th positioning
Hole 3 be respectively positioned on it is corresponding positioning copper ring 2 inner circle 201 in, then illustrate the inclined situation in hole of this each location hole 3 be successively: greater than
1.5mil, it is greater than 2mil, is equal to 2.5mil, is not more than 3mil, is not more than 3.5mil, to sum up, the hole offset distance of this machine drilling
From equal to 2.5mil；
As shown in figure 3, if first and second location hole 3 are partially or entirely located in corresponding positioning copper ring 2
Except inner circle 201,3 part of third location hole is intersected with the inner circle 201 of corresponding positioning copper ring 2, and the 4th and the 5th
Location hole 3 is respectively positioned in the inner circle 201 of corresponding positioning copper ring 2, then illustrates that the inclined situation in hole of this each location hole 3 is successively:
Greater than 1.5mil, be greater than 2mil, be greater than 2.5mil, no more than 3mil, be not more than 3.5mil, to sum up, the hole of this machine drilling
Offset distance is from greater than 2.5mil and no more than 3mil.
So analogize, change by visual observation it may determine that be hole offset distance from approximate range, between adjustment positioning copper ring 2
Internal diameter difference between spacing and adjacent positioning copper ring 2, can also further be adjusted the accuracy of measurement result.This
Cumbersome analysis directly can be verified process visualizing, letter by the inclined distance measurement method in hole for the machine drilling that embodiment provides
It is single efficient.
Specifically, for machine drilling, if positioning copper ring 2 is replaced using circular locating plate, due in locating plate
Between be solid rather than hollow out, locating plate drilling after inner wall be easy etching when be snapped erosion, cause influence visualizing judgement
As a result.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
Invention is explained in detail, those skilled in the art should understand that: it still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features；And these modification or
Replacement, the spirit and scope for technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution.
