Inductor and manufacturing method thereof

Abstract

The invention discloses an inductor and a manufacturing method thereof. The manufacturing method of the inductor comprises the following steps of S1, magnetic core manufacturing: pressing pelleting magnetic powder into a high-density block body; then, cutting the high-density block body into a magnetic core structure; sintering the magnetic core structure into a compact state, wherein a magnetic core comprises a middle post and two swinging blades; S2, coil winding: winding a coil on the middle post; after the winding, enabling the cross section of the coil to be parallel to the long and highplane of the inductor, wherein the two leading-out ends of the coil are positioned at two sides of the middle post and are positioned on the same plane; S3, compression molding: filling the bottom ofa mold with a layer of pelleting magnetic powder for prepressing compaction; then, implanting the magnetic core wound with the coil in the step 2 into the mold; after the implantation, fully filling the mold with the pelleting magnetic powder for compression molding; S4, semi-finished product heat treatment; S5, end electrode manufacturing. The inductor and the manufacturing method thereof have the advantage that on the basis of obtaining the inductor with great induction quantity, higher self-resonant frequency is realized.

Description

【Technical field】 [0001] The invention relates to an inductance device and a manufacturing method. 【Background technique】 [0002] As electronic devices tend to be miniaturized and high-frequency, but the self-resonance frequency has not been improved accordingly, which greatly affects the application of the product. At present, the common one-piece inductance device has a larger coil cross-sectional area, and the same inductance requires fewer turns. However, with the development of miniaturization and thinner inductance devices, the self-resonant frequency is limited, and the application range is hindered. . [0003] The disclosure of the above background technical content is only used to assist in understanding the inventive concepts and technical solutions of the present invention, and it does not necessarily belong to the prior art of this patent application. There is no clear evidence that the above content has been disclosed on the filing date of this patent applicat...
