Embodiment Construction

[0024] The ferrite consistency detection jig and detection method proposed by the present invention are described below with reference to the accompanying drawings and specific embodiments.

[0025] for further details. It should be noted that, the accompanying drawings are all in a very simplified form and in inaccurate scales, and are only used to facilitate and clearly assist the purpose of explaining the embodiments of the present invention. Furthermore, the structures shown in the drawings are often part of the actual structure. In particular, each drawing needs to show different emphases, and sometimes different scales are used.

[0026] It should be noted that “first”, “second”, etc. in the description and claims of the present invention and the description of the drawings are used to distinguish similar objects, so as to describe the embodiments of the present invention, rather than to describe a specific order or precedence, it should be understood that the structur...

Abstract

The invention provides a ferrite consistency detection jig and detection method. The ferrite consistency detection jig comprises a substrate, a coil, a matching circuit and a network analyzer, the coil and the matching circuit are printed on the surface of the substrate, and the coil is electrically connected with the network analyzer through the matching circuit; the ferrite detection jig is configured to place standard ferrite on the surface of the area, printed with the coil, of the substrate, debug the matching circuit to enable the frequency range displayed by the network analyzer to be within the preset frequency range, and replace the ferrite to be detected for consistency detection. Based on the principle that corresponding electromagnetic frequency can be displayed on the network analyzer through electromagnetic induction between the coil and the ferrite, the electromagnetic frequency of the standard ferrite is enabled to be within a preset frequency range through debugging of the matching circuit, and then the ferrite to be detected is replaced for testing; and therefore, consistency of the ferrite can be confirmed by judging whether the frequency displayed on the network analyzer is within the preset frequency range or not, and a problem of how to detect consistency of the ferrite is solved.

Description

technical field [0001] The invention relates to the technical field of ferrite detection, in particular to a ferrite consistency detection fixture and a detection method. Background technique [0002] Ferrite, also known as magnetic ceramics, refers to a composite oxide magnetic material composed of iron ions, oxygen ions and other metal ions. It is characterized by high initial permeability, easy magnetization and easy demagnetization. Ferrite is a functional material with a wide range of uses. As one of the basic materials in the electronics industry, it has been greatly developed in recent years. Many new ferrites have been researched and developed, such as high-frequency low-power ferrites for switching power supplies, broadband microwave absorption ferrites, high-coercivity nanocrystalline magnetic ceramics and magnetically ordered materials, and room temperature magnetic refrigeration materials. and many more. [0003] As NFC (Near Field Communication Technology) dev...
