Abstract

A process of manufacturing inductor includes preparing coil, using a composite material to prepare a T-core and a U-core, disposing the coil in the cavity of the U-core with the extensions disposed externally of the cavity, inserting the projection through the coil with the cavity being covered by the platform, bending the extensions, heating the assembled U-core, the coil, and the T-core to form a half-finished product, baking the half-finished product, painting and peeling the baked half-finished product, and surface treating the peeled half-finished product by electroplating a composite layer on exposed surfaces of the extensions to obtain an inductor. The composite layer includes, from inside to outside, a copper layer, a nickel layer, and a tin layer.
