The test board assembly and the inspection apparatus according to the embodiments of the present utility model will be described in detail with reference to fig. 1 to 11.

FIG. 1 is a schematic structural view of the test board assembly of the present utility model, which does not represent the actual structure of the test board assembly of the present utility model, as shown in FIG. 1, and includes: detection circuitry 110, conductive elements 120, and interconnect lines 130.

In the related art, a part of the board body needs to be connected with other board bodies to work together in the working process, and at the moment, a circuit in the part of the board body and a circuit in the other board bodies can form a working circuit; when circuits of the part of the board body facing the other board bodies need to be detected, the other board bodies need to be separated from the part of the board bodies, and at the moment, the part of the board bodies cannot form a working circuit and the circuits in the part of the board bodies cannot be detected; the circuit on the board body 200 to be tested forms a working loop through the interconnection circuit 130; the detection circuit 110 is electrically connected with the board to be detected 200 through the conductive component 120, and the detection circuit 110 can form an electrical connection with the circuit to be detected 210 in the circuit on the board to be detected 200 through the conductive component 120 to form a detection loop, so that the working parameters of the circuit to be detected 210 can be detected through the detection circuit 110.

In the embodiment of the present utility model, the detection circuit 110 can detect the power consumption or the current of the electronic component in the circuit 210 to be detected. For example, as shown in fig. 2, the detection circuit 110 may include a resistor 170. By detecting the voltage across the resistor 170, the current of the circuit under test 210 can be obtained, thereby realizing the detection of power consumption.

In some embodiments, an inductor is connected in series to the output end of the power module to work normally. Referring to fig. 2, the circuit under test 210 may include a power module (not shown), an inductor 190 and a device under test 250, and the current of the detection circuit 110 can be determined by detecting the voltage difference across the resistor 170, and since the detection circuit 110 and the circuit under test 210 are connected in series to form a detection loop, i.e. the current of the circuit under test 210 can be determined, at this time, the power consumption of the device under test 250 in the circuit under test 210 can be determined. Of course, the power consumption of the device under test 250 in the circuit under test 210 may also be determined by directly detecting the current of the detection circuit 110.
