And when the communication is successfully established, the circuit board to be detected enters a preset test state. The circuit board testing device enables a circuit board to be tested to enter various testing states, and collects the same voltage, current and/or level logic in the various testing states, so that the circuit board to be tested is more comprehensively tested, and the reject ratio is reduced. And then, the circuit board testing device collects the feedback signal of the circuit board to be detected and compares the feedback signal with the standard signal value stored in the storage unit to form a comparison result.
Further, in the embodiment of the invention, when a plurality of circuit boards to be detected are accessed (for example, the first type circuit board and the second type circuit board are accessed simultaneously), the circuit board testing device detects the plurality of circuit boards to be detected simultaneously.
Step S400: and the display unit of the circuit board testing device displays the detection result. In the embodiment of the invention, when the data received from the detected first type circuit board or second type circuit board is judged to be fault data after comparison, a fault code is formed according to the corresponding detection content, wherein the fault code gives details of each fault of the detected first type circuit board or second type circuit board.
Further, in an embodiment of the present invention, the method for testing a circuit board includes a self-checking step, that is, the self-checking unit performs self-checking on the internal detection environment of the circuit board testing apparatus before detecting the first type circuit board and/or the second type circuit board (before step S200). More specifically, it is preferable that, in order to ensure that the circuit board testing apparatus itself is good before each inspection, the circuit board testing apparatus is subjected to a self-inspection before each inspection of the circuit board, and whether the internal test environment of the circuit board testing apparatus is normal is detected, thereby ensuring that each inspection is accurate.
In summary, in the circuit board testing apparatus and the circuit board testing method provided in the embodiments of the present invention, since the circuit board testing apparatus includes the first type circuit board access portion and the second type circuit board access portion, the first type circuit board and the second type circuit board can be simultaneously detected, and the detection speed of the circuit board is increased.
