Method of producing a surface-mount inductor
Abstract:
A method of producing a surface-mount inductor by encapsulating a coil with an encapsulation material containing a resin and a filler using a mold die assembly is provided. In the method, a tablet and a coil are used. The tablet is prepared by preforming the encapsulation material into a shape having a flat plate-shaped portion and a pillar-shaped convex portion on a peripheral thereof. The coil is a wound conductive wire having a cross-section of rectangular-shape. The coil is placed on the tablet to allow both ends of the coil to extend along an outer side surface of the pillar-shaped convex portion of the tablet. The coil and the encapsulation material are integrated together while clamping the both ends of the coil between an inner wall surface of the mold die assembly and the outer side surface of the pillar-shaped convex portion of the tablet, to form a molded body. External electrodes are formed on a surface of or around an outer periphery of the molded body in such a manner that the external electrodes are electrically connected to the both ends of the coil at least a portion of which is exposed to the surface of the molded body.
