Manufacturing method of coil embedded type inductor using soft magnetic molding liquid and coil embedded type inductor

摘要

The present invention relates to an optimal condition in which a composition of a soft magnetic molding solution includes 94 to 98 wt% of a soft magnetic powder and 2 to 6 wt% of an organic vehicle, in order to manufacture a coil-embedded inductor having various advantages such as high inductance, a low core loss, and high reliability. Provided is a manufacturing method of a coil-embedded inductor having a structure in which a part of a coil is embedded in a magnetic core, which includes preparing an organic vehicle, preparing a soft magnetic molding solution having the density of 5.5 to 6.5 g/cc by mix-milling a soft magnetic powder with the organic vehicle, positioning and fixing a part of the coil in the case, and forming the magnetic core by injecting and curing the soft magnetic molding solution into the case.
