1. , a kind of printed circuit board (PCB) loop-around test system is characterized in that this system comprises:

  • Data acquisition module is used for gathering the inductance value in each printed circuit board (PCB) loop of standard printed circuit board and storing database into;

    And the inductance value of gathering each printed circuit board (PCB) loop of printed circuit board (PCB) to be measured, and send to data contrast module;

    Database is used to store inductance value, test stone, the measuring current value in each printed circuit board (PCB) loop of standard printed circuit board of data collecting module collected;

    Data contrast module, be used to receive the inductance value in each printed circuit board (PCB) loop of printed circuit board (PCB) to be measured that data acquisition module sends, from database, read the inductance value in the printed circuit board (PCB) loop of corresponding standard printed circuit board (PCB), and the deviation value of the inductance value in corresponding printed circuit board (PCB) loop in the inductance value in each printed circuit board (PCB) loop of printed circuit board (PCB) more to be measured and the standard printed circuit board, each deviation value is all in the test stone scope as described, send described printed circuit board (PCB) to be measured to data outputting module and pass through checking information, arbitrary as described deviation value sends described printed circuit board (PCB) to be measured to data outputting module and does not pass through checking information not in the test stone scope;

    Data outputting module is used to receive testing result and the output that data contrast the printed circuit board (PCB) to be measured of module transmission.
