SURFACE-MOUNT INDUCTOR AND A METHOD FOR MANUFACTURING THE SAME
A surface-mount inductor, having a coil formed by winding an insulated wire, and a mounting body incorporating the coil where the coil has lead ends, which are extended over the mounting face of the mounting body, the mounting face has a recessed portion formed by removing insulation of the lead ends, and the recessed portion is filled with sealant to make the mounting face of the mounting body flat, as well as a method for manufacturing the same are herein disclosed.
1 . A surface-mount inductor having a coil made by winding an insulated wire, and a mounting body accommodating the coil inside, wherein
the coil has lead ends,
the lead ends extend over a mounting face of the mounting body,
the mounting face of the mounting body has a recessed portion formed by removing insulation from the lead ends, and
the recessed portion is filled with metal so that the mounting face of the mounting body are flat.
2 . The surface-mount inductor according to claim 1 , wherein
the recessed portion is filled with a metal layer consisting of a combination of an Sn layer, an Ag layer and a Ni layer.
3 . A method for manufacturing a surface-mount inductor having a coil made by winding an insulated wire, and a mounting body accommodating the coil inside, comprising the steps of:
forming a coil;
incorporating the coil in the mounting body and extending lead ends of the coil over the mounting face of the mounting body;
removing insulation from the lead ends; and
filling a recessed portion, formed by removing insulation from the lead ends, with metal to form a surface to be level with the mounting face of the mounting body so as to make external terminals.
