Inductor manufacturing method and inductor manufactured through inductor manufacturing method

Abstract

The invention discloses a manufacturing method of an inductor and the inductor manufactured through the method. The manufacturing method of the inductor comprises the steps that a lead is welded to a soldering lug at the leading-out end of a coil; heating a mold, and after the mold is heated to a first preset temperature, putting a soldering lug with a lead into the mold; loading a bulk molding compound into the mold, and plasticizing the bulk molding compound to enable the bulk molding compound to flow and fill a mold cavity of the mold; according to the manufacturing method of the inductor, the soldering lug with the lead is placed in the mold, the bulk molding compound is placed in the mold, the bulk molding compound is plasticized and flows to fill the mold cavity of the mold, and the molding process of curing and demolding after curing is completed is carried out, so that the inductor is manufactured. When tests such as vibration, impact and the like are carried out, the unshelling phenomenon does not occur, the impact and vibration resistance of the product is improved, and the reliability of the product is improved.

Description

technical field [0001] The present invention relates to the technical field of electronic components, in particular to a method for manufacturing an inductor and an inductor manufactured by the method, in particular to a method for manufacturing a highly reliable inductor and a highly reliable inductor manufactured by the method . Background technique [0002] Inductors currently on the market are usually packaged by potting technology, and the structure is as follows figure 1 As shown, the specific process is to weld the lead wire 11 to the lead-out end of the coil 13, put it into the casing 14, and then use glue for potting. However, the inductor products made by this process are prone to defects such as depressions and cracks on the surface of the potting compound 15, and are prone to shelling during vibration and impact tests, resulting in poor reliability of the inductor. Contents of the invention [0003] For this reason, the present invention provides a kind of ma...
