Abstract
A coil component includes a body, and a coil portion embedded in the body and including a coil pattern having a plurality of coil turns and a support member supporting the coil pattern. A height of an internal coil turn of the plurality of coil turns is lower than a height of an external coil turn of the plurality of coil turns connected to the internal coil pattern and wound outwardly of the internal coil turn. A method of manufacturing the coil component includes forming a spiral-shaped plating seed pattern on a support member, forming a cutting portion cutting the spiral-shaped plating pattern, and forming a coil pattern extending across the cutting portion by performing plating on the spiral-shaped plating seed pattern.
Claims27
A coil component comprising:
- a body;
- and
- a coil portion embedded in the body and including a coil pattern having a plurality of coil turns and a support member supporting the coil pattern,
- wherein a height of an internal coil turn of the plurality of coil turns is lower than a height of an external coil turn of the plurality of coil turns connected to the internal coil pattern and wound outwardly of the internal coil turn.
A method of manufacturing a coil component including a body having a coil portion embedded therein, comprising:
- forming a spiral-shaped plating seed pattern on at least one surface of a support member;
- forming at least one cutting portion cutting the spiral-shaped plating seed pattern;
- forming pattern walls on both sides of the spiral-shaped plating seed pattern;
- and
- forming a coil pattern extending between the pattern walls by a plating process using the spiral-shaped plating seed pattern.
A method of manufacturing a coil component, comprising:
- forming first and second plating seed patterns on a surface of a support member, wherein the first and second plating seed patterns are spaced apart from each other by a cutting portion;
- forming a first plating layer on the first plating seed pattern only by performing a first plating process using the first plating seed pattern only from among the first and second plating seed patterns;
- and
- following the forming of the first plating layer, forming a second plating layer on the first and second plating seed patterns by performing a second plating process using the first and second plating seed patterns.
A coil component comprising:
- a support member;
- and
- a plating seed pattern disposed on a surface of the support member and having a coil shape having a plurality of windings,
- wherein the plating seed pattern comprises a plurality of segments that are spaced apart and isolated from each other by one or more cutting portions.
