Description
Technical field
The present invention relates to printed-board technology fields, particularly, are related to a kind of printed circuit board Auto-Test System.
Background technology
Each coil circuit itself that circuit is formed in the circuits PCB is to be in consolidated network, i.e., is mutually to be on shape
State, when there is short circuit originally between the PCB circuit coils of mutual conduction in consolidated network, the variation of resistance value is
It is very small, it can not be detected at all under existing resistance test precision, so, mesh can only be passed through to the circuits PCB at present
Whether inspection line inspection circle is intact, and for multi-layer PCB, internal layer PCB is separated by insulating layer and outer layer PCB, then again by internal layer
PCB, insulating layer and outer layer PCB pressings, in this way, internal layer PCB circuit coils are not visible so that the inner coil of PCB finished products can not
Automatic detection.
Invention content
Present invention aims at a kind of printed circuit board Auto-Test System is provided, to solve in the prior art, PCB finished products
Inner coil the technical issues of can not detecting automatically.
To achieve the above object, the present invention provides a kind of printed circuit board Auto-Test System, including：Data acquisition module
The input terminal of block, database and user interface, the data acquisition module is connected with circuit board under test, the data acquisition module
The output end of block is connected with the input terminal of the database, and the output end of the database is connected with the user interface,
Data comparison module is provided in the database.
Further, it is provided with standard value memory module in the data comparison module.

It is connected, data comparison module is provided in the database.Data acquisition module detects printed circuit board and respectively prints electricity automatically
The inductance value in road plate circuit is simultaneously transmitted to database, and after database is by data comparison module, comparing result is sent to user
Interface.The system is changed by automatic measurement inductance, to differentiate the short-circuit conditions in circuit, is differentiated compared to traditional resistance variations,
Inductance variation is more readily detected, and measuring accuracy higher can not be automatic to PCB circuit coils finished product in PCB industries to solve
The problem of detecting inner coil.
Preferably, it is provided with standard value memory module in the data comparison module.Compare test print circuit board respectively to print
The deviation value of the inductance value in the inductance value in printed circuit board circuit printed circuit board corresponding with standard printed circuit board circuit, such as
Each deviation value sends the test print circuit board by checking information within the scope of test stone, to user interface,
If a certain deviation value sends the not verified letter of test print circuit board not within the scope of test stone, to user interface
Breath.
Preferably, the standard value memory module is at least arranged one, plays control.
Preferably, it is provided with operating system and display system in the user interface, display inspection is carried out by display system
Survey result.
It can be seen from the above description that the above embodiments of the present invention realize following technique effect：The system is logical
The variation of automatic measurement inductance is crossed, to differentiate the short-circuit conditions in circuit, is differentiated compared to traditional resistance variations, inductance variation is easier
Detection, measuring accuracy higher can not detect inner coil automatically to solve in PCB industries to PCB circuit coils finished product
Problem.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention；For the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
