Technical field
The present invention relates to PCB impedance informations to acquire field, in particular to a kind of PCB impedance information automatic collection and analysis side
Method.
Background technique
With the swift and violent raising and the extensive use of high-frequency circuit of signaling rate, printed circuit board also proposed
Higher requirement will obtain the transmission signal of complete, reliable, accurate, noiseless noise it is necessary that printed wiring board circuit
It is low that reflex, signal integrity, transmission loss do not occur in transmission process for signal, plays the role of matching impedance, meanwhile, it is right
For PCB manufacturer, other than short, the breaking qualification of pcb board to be guaranteed, also to guarantee impedance value within the limits prescribed, only
The all qualified printing plate in the two directions just really meets the requirements of the customers.
To sum up, it is necessary to obtain the data of pcb board testing impedance in time and analyze it, improve, therefore testing impedance
The timely acquisition of data is particularly important, however the acquisition of existing pcb board testing impedance data often stores data
It behind backstage, is acquired again after a period of time, and impedance data process flow confusion causes data pipe random.
Summary of the invention
It is an object of the invention to a kind of PCB impedance informations for solving shortcoming in the prior art and providing to adopt automatically
Collection and analysis method, not prompt enough for solving current pcb board impedance information acquisition, flow chart of data processing confusion leads to data
The situation of pipe unrest.
The purpose of the present invention is achieved through the following technical solutions:
A kind of pcb board impedance information automatic collection and analysis method, which comprises the following steps: (a) passes through impedance and survey
It tries instrument and obtains pcb board testing impedance data；(b) test data is stored in impedance instrument backstage；(c) test data save to
After impedance instrument backstage delay 3 minutes, IT program determines test data, then valid data are sent to ERP system；
(d) test data file is compared with the last modification date of file, file size in ERP system record, as long as there is one
Difference then needs to re-read file content, only when the last modification day of file in test data file and ERP system record
When phase, file size are all identical, just the data correlation of acquisition to ERP system；(e) test data processing is report by ERP system
The form of table.
Further, the impedance instrument is specially Polar CITS800s4/CITS900s4 impedance machine.
Further, the impedance data for being stored in backstage is clf format file.
Further, the clf format file content is English or Chinese.
Further, the IT program is adapted to distinct device/software version.
Further, the test data includes corresponding model, and testDate qualification points, fail points, qualified clusters number,
Failure group number.
The beneficial effects of the present invention are: compared to the prior art, the present invention is realized by IT program to testing impedance data
Timely automatic identification and acquisition, then simple and clear report form is showed by ERP system, not only increase the people of company
Member's efficiency facilitates analysis, is conducive to improve, and thus extends, also provides possibility for company's other equipment automatic data collection, simultaneously
Also realize that intelligent production provides reliable basis for company.

Specific embodiment
The invention will be further described with the following Examples.
Embodiment 1
A kind of pcb board impedance information automatic collection and analysis method of the present embodiment, as shown in Figure 1, the present embodiment includes following
Step :(a) pcb board testing impedance data are obtained by impedance instrument；(b) after test data being stored in impedance instrument
Platform；(c) test data is saved to impedance instrument backstage delay 3 minutes, and IT program determines test data, then will have
Effect data are sent to ERP system；(d) test data file and the last modification date of file, file size in ERP system record
It is compared, when the last modification date of file, file size are different from test data file and ERP system record,
The data correlation of acquisition to ERP system；(e) form that ERP system is handled test data as report.
In the present embodiment, preferably, impedance instrument selects Polar CITS800s4/CITS900s4 impedance
Machine, the impedance machine can provide difference and single-ended measurement function, four channels of the band for flexible probe connection, core TDR mould
Group dominant frequency bandwidth 1.75GHZ, stay in grade, precision is accurate, and antistatic effect is strong.
