Abstract
A circuit board having an embedded inductor and a process for making the circuit board is provided. In general, the process begins by providing a core structure including a dielectric core layer and a first metal layer on a top surface of the dielectric core layer. The first metal layer is etched to form first inductor windings. A material, such as an epoxy material, including magnetic filler material is deposited over the first inductor windings. Thereafter, a prepreg layer is placed over and attached to the material deposited over the first inductor windings to form the circuit board having the embedded inductor.
