Problems solved by technology

[0004] The production of the above-mentioned coils needs to be realized by processes such as vacuum coating, photolithography and electroplating copper plating. The insulating film needs to be made by screen printing, photoresist exposure and development or spraying application. In addition, the insulating substrate needs to be made of, for example, a polypropylene glycol substrate. Or ferrite substrate and other materials, the production process is more complicated, and the production cost is higher

Abstract

The invention belongs to the technical field of inductors, and discloses an inductor and a manufacturing method thereof. According to the inductor, a first coil and a second coil are manufactured through enameled flat copper wires, on one hand, the thickness-width ratio of the coils can be increased, meanwhile the production processes of vacuum coating, photoetching, electroplating copper deposition and the like can be omitted, and the production process is effectively simplified, and the production cost is reduced; and on the other hand, a copper wire adopts an enameled structure, so that the insulation effect of the coils is directly realized, one end face of the first coil can be attached to one end face of the second coil, the other end face of the first coil can be attached to the inner wall of a substrate-containing cavity, the other end face of the second coil can be attached to the inner wall of the substrate-containing cavity, and an insulating substrate and an insulating film are omitted, so the structure of the inductor is effectively simplified, meanwhile, the production process is simplified, and the production cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of inductors, and in particular, to an inductor and a manufacturing method thereof. Background technique [0002] Inductors are components that can convert electrical energy into magnetic energy and store them. With the continuous development of electronic power technology and people's diversified use requirements for inductor products, high-current, low-loss and low-cost inductor products are gradually accepted. favored by the market. The larger the aspect ratio of the inductor coil, the smaller the resistance of the coil, that is, the smaller the loss. [0003] In order to improve the aspect ratio of the coil, the prior art discloses an inductor, which includes a first coil and a second coil, each coil is formed by at least two layers of wire patterns, and each coil is provided with a covering conductive pattern The outer side of the surface coating is provided with a plating layer to achieve the...
