Abstract
The utility model discloses the pcb board with test boring, is equipped on four corners of the pcb board and is respectively equipped with a graphics field, and one group of test boring and alignment target are equipped in each graphics field.The pcb board with test boring of the application provides graph area and carries out test boring on it for drilling personnel, and the problem of be adjusted according to test boring, prevent offset.
Description
Technical field
The utility model is related to pcb board manufacture fields, more specifically, a kind of pcb board with test boring.
Background technology
Pcb board is subject to cover plate materials such as that improper, base material is selected to generate harmomegathus, drill bit operation production during Drilling operation
The influence of raw resonance etc. factor can often lead to the problem of offset.And when there is the problem of offset apertures, it can only be straight by pcb board
It is informed of a case useless, cost of idleness.
Utility model content
Since the prior art is there is the above problem, the utility model proposes a kind of pcb boards with test boring, can be effective
Solution problems of the prior art.
The utility model solves the above problems by the following technical programs：
Pcb board with test boring is equipped on four corners of the pcb board and is respectively equipped with a graphics field, and each
One group of test boring and alignment target are equipped in graphics field, the alignment target is concentric with the test boring and diameter is more than institute
State the diameter of test boring.
It is preferred that each group of test boring includes 5 test borings, every group of test boring is apart from the corner of the pcb board
For 5-20 millimeters, and every test drilling interporal lacuna is 1.5 millimeters.
It is preferred that each test boring in each group of test boring apart from the gap of graphics field be respectively 1 mil, 2 mils,
3 mils, 4 mils and 5 mils.
Exist due to providing graph area using the pcb board with test boring of above-mentioned technological means, the application for drilling personnel
The problem of carrying out test boring thereon, and being adjusted according to test boring, prevent offset.
Description of the drawings
Fig. 1 is the structure diagram of one embodiment of the utility model.
Specific embodiment
With reference to embodiment, the utility model is described in detail.
Shown in Figure 1, Fig. 1 is the structure diagram of one embodiment of the utility model.
Pcb board with test boring is equipped on four corners of the pcb board 1 and is respectively equipped with a graphics field 2, and every
One group of test boring and alignment target 3 are equipped in one graphics field 2, the alignment target is concentric with the test boring and diameter is big
In the diameter of the test boring.
As shown in Figure 1, each group of test boring include 5 test borings 21,22,23,24 and 25, every group of test boring away from
Corner from the pcb board 1 is 5-20 millimeters, and the gap between every test boring is 1.5 millimeters.In each group of test boring
Each test boring is respectively 1 mil, 2 mils, 3 mils, 4 mils and 5 mils apart from the gap of graphics field.I.e. test boring 25 away from
Gap from graphics field is 1 mil, and test boring 24 is apart from 2 mil of the gap of graphics field, test boring 23 apart from graphics field
3 mil of gap, test boring 22 apart from 4 mil of the gap of graphics field, test boring 21 apart from 5 mil of the gap of graphics field.
The present embodiment can cause operator to carry out test boring on the pcb board in identical material, avoid material difference
When image, in addition, by pcb board test boring, according to the situation of drilling into the instant adjustment of line displacement.
It is to be understood that these embodiments are merely to illustrate the utility model rather than limitation the scope of the utility model.
In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art can make the utility model
Various changes or modification, these equivalent forms also fall within the scope of the appended claims of the present application.
