Abstract
The invention relates to an integrally-formed inductor and a manufacturing method thereof, the integrally-formed inductor comprises a magnetic body, a hollow coil and a conductive layer, the hollow coil is provided with an embedded part and an exposed part, the embedded part is embedded in the magnetic body, and the exposed part is arranged on the embedded part and located outside the magnetic body; the conductive layer comprises a copper-containing coating and a tin-containing coating, the copper-containing coating is coated on the exposed part, and the tin-containing coating is coated on the copper-containing coating; according to the integrally formed inductor and the manufacturing method thereof, the exposed part of the hollow coil is coated with the copper-containing coating and the tin-containing coating in sequence, so that the copper-containing coating and the tin-containing coating can be generated on the terminal surface of the inductor; compared with a mode of forming the connection terminal through an external guide sheet, a mode of extending a copper wire outwards or a mode of electroplating, the mode of forming the connection terminal through a printing mode is low in cost, and the manufacturing process is simple.
