Wherein the coil assembly 204 is located on the element 203 inducing magnetic flux and the communication interface 205 is also located on the FPC board 202. The communication interface 205 is electrically connected to the coil block 204 and the magnetic flux inducing element 203 through the FPC board 202, respectively. As shown in fig. 1, the coil assemblies and the magnetic members are in a one-to-one correspondence relationship, that is, when there are two coil assemblies 204, there are also two corresponding magnetic members 103, but of course, there may be two or more, and the present invention is not limited thereto.
In this embodiment, the first end portion a of the first fixing plate 101 is connected to the second end portion B of the second fixing plate 201 through a rotating mechanism 301, so that the first fixing plate 101 rotates around the rotating mechanism 301, and the first fixing plate 101 and the second fixing plate 201 form a predetermined angle, in this embodiment, the rotating mechanism 301 is specifically a rotating shaft and the like.

In this embodiment, when the first fixing plate and the second fixing plate are rotationally locked, the magnetic component 103 faces the circuit board to be tested. Specifically, the size of the magnetic component 103 is slightly larger than the size of the coil assembly 204, so that when the first fixing plate 101 is fastened to the second fixing plate 201, the magnetic component 103 is located above the coil assembly 204, wherein the coil assembly 204 is specifically a coil winding, and the coil winding includes a hollow portion, and only when the magnetic component 103 is larger than the size of the coil assembly 204, the magnetic component 103 does not fall into the hollow portion of the coil assembly 204, so that the magnetic component 103 is located above the coil assembly 204.

The upper computer or the computer judges the received magnetic flux, and compares the two magnetic fluxes induced by the two magnetic flux inducing elements 203 because the magnetic fluxes of the two magnetic flux inducing elements 203 are received, and if the difference between the two magnetic fluxes is larger, the upper computer or the computer shows that the magnetic flux inducing elements 203 are normal and the assembly damage does not occur; if the two magnetic flux values are not very different, i.e., difficult to distinguish, the component 203 that induces the magnetic flux is welded or damaged in assembly.
The test board can also test whether the coil component 204 is damaged, and by recording the introduced current value and receiving the actual current value by the upper computer, when the actual current value is halved relative to the introduced current value, the coil component 204 is determined to have a fault in the assembling process.
By the testing mode, whether each device is damaged or not is tested before the T-FPC board is assembled, so that bad conditions can be intercepted before finished products, and the yield is further improved. Of course, the test board can also test other types of circuit boards, and will not be described in detail herein.
And after the test is finished, replacing another circuit board to be tested to carry out a test step of another circuit board to be tested.
