A method of producing layered cores for magnetic circuit components such as inductors and transformers suitable for use in the microelectronics industry. A series of pillars are created on a carrier Layers of the magnetic core are plated onto the exposed surface of the pillars. After the desired number of core layers are plated, the plated layers are ground down to expose the pillars, leaving a series of magnetic cores between the pillars. The pillars can then be removed, leaving a series of magnetic cores. The pillars are created by either building up pillars, such as copper pillars, or by slitting plastic mediums, such as dry film or epoxy plastic, the roughness of the magnetic cores produced depends on the method of forming the pillars.

The present disclosure generally relates to techniques for magnetic electro-plating or electro-deposition. Example methods may include utilizing a magnet during electro-deposition to modify kinetics of deposition of plating material on a substrate.
