Abstract
A manufacturing method of a coil component including the steps of: holding a plurality of semi-finished products, each of which includes a base and a coil before forming the coil component, with a jig having a holding portion; setting the plurality of semi-finished products held by the jig to the setting positions of the jig in a mold; and sealing at least a portion within the base and the coil with resin by filling the resin into a cavity of the mold.
Claims8
A manufacturing method of a coil component comprising the steps of:
- preparing a plurality of semi-finished products, each of the plurality of semi-finished products is configured with a base, a coil, and a held member;
- preparing a jig, the jig having a plurality of holding members, the jig being configured with a lower jig and an upper jig;
- placing each of the held members of the plurality of semi-finished products to each of the holding members of the jig so that the plurality of semi-finished products are held by the jig;
- placing the plurality of semi-finished products held by the jig in an inner space of a mold so that the plurality of semi-finished products are set at a setting position in the inner space of the mold;
- and
- filling a resin in the inner space of the mold to seal part of each of the plurality of semi-finished products with the resin so that a plurality of molded products are formed,
- wherein, when each of the held members of the plurality of semi-finished products is placed to each of the holding members of the jig, each of the semi-finished products is sandwiched between the lower jig and the upper jig.
A jig used for manufacturing a coil component, the coil component being formed by each of a plurality of semi-finished products, each of the semi-finished products being configured with a base, a coil assembled to the base, and a metal lead frame fixed to the base, a first area of each of the metal lead frames outwardly extending from the base in a first direction, the jig comprising:
- a longitudinal plate extending in a second direction perpendicular to the first direction, the longitudinal plate having first and second sides basing each other and third and fourth sides facing each other, the first and second sides being longer than the third and fourth sided;
- a fixing plate that is attachable to the longitudinal plate;
- and
- a plurality of holding members that are disposed along the first of the longitudinal plate, the plurality of holding members being spaced apart from each other via a first interval aloe the first direction,
- wherein when each first area of the metal lead frames of the plurality of semi-finished products is placed at each of the holding members at the first interval, each first area is sandwiched between the longitudinal plate and the fixing plate so that each of the coils and the bases of the plurality of semi-finished products extends from the jig in the first direction.
