Description

Technical Field

[0001] The invention relates to the technical field of inductance testing, and in particular to a multi-channel inductance testing device. Background Art

[0002] During the production of electronic products, the inductance of the product needs to be tested to avoid electronic products with large parameter errors from entering the market. An inductor is an electronic component that can store electrical energy and convert it into magnetic energy. When testing an inductor, it is usually necessary to pay attention to whether it is damaged and whether its inductance meets the nominal value. The structure of an inductor is similar to that of a transformer, but it has only one winding, generally consisting of a skeleton, winding, shielding cover, packaging material, magnetic core or iron core, etc. If the inductor is in a state where there is no current flowing through it, it will try to prevent the current from flowing through it when the circuit is connected. If the inductor is in a state where there is current flowing through it, it will try to maintain the current unchanged when the circuit is disconnected.

[0003] According to a Chinese patent with publication number "CN117233472A", a multi-channel inductance test device is disclosed. The multi-channel inductance test device includes an inductance tester, a multi-channel controller, an inductance test fixture and a calibration aluminum sheet. The multi-channel controller includes an input end and multiple output ends, and the output ends are respectively connected to the points to be tested, so that the inductance tester can perform inductance tests on multiple points to be tested at the same time; the inductance test fixture is provided with multiple probe groups, and when the product to be tested is placed on the inductance test fixture, each point to be tested of the product to be tested is connected to the inductance tester through a probe group; the calibration aluminum sheet is used to be placed on the inductance test fixture before testing the product to be tested to perform inductance testing, and the inductance test of the product to be tested is calibrated by the inductance test results. Through the above-mentioned multi-channel inductance testing device, before performing batch inductance testing on multiple test points, inductance test calibration can be performed to make the inductance test result more accurate, and nanohenry-level inductance testing can be performed. When in use, the inductance voltage testing device generally only uses one set of detection heads to detect the inductance, and manual alignment of the detection position is required, which reduces the overall detection speed and thus reduces the overall detection efficiency. Therefore, a multi-channel inductance testing device is proposed to solve the above-mentioned problems. Summary of the invention
