摘要： An apparatus and method for plating magnetic cores by periodically transferring a plate directly back and forth between a metal plating environment and an insulation deposit environment. This direct metal to insulation to metal plating is enabled by a nano-scale insulation layer that provides an imperfect coverage of the metal layer while still keeping sufficient insulation to prevent eddy current formation—even during high-frequency current applications. Therefore, this invention enables the practical creation of magnetic cores having layers with widths even under one nanometer and can generate cores having a layer scale that can be varied to suit a variety of uses in the microelectronic industry.
