Improved thin power inductor manufacturing process

An improved thin power inductor manufacturing process comprises the steps of forming a spiral inductance coil through metal mask, a sputtering process and a copper electroplating process on a base plate; then printing an adhesive configured for a magnetic material on the outside of the spiral inductance coil so as to form an insulation coating layer and accordingly form a single-layer power inductor; sequentially manufacturing multiple-layer power inductors above the single-layer power inductor and enabling the multiple-layer power inductors to be mutually communicated when repeating the steps and accordingly forming a continuous spiral inductance coil.
