## Abstract

A magnetic inductor coil printing method includes the step of printing at least one first coil winding on a core base, the step of printing a first insulating layer on the core base over the first coil winding, the step of printing at least one second coil winding on the core base over the first insulating layer, and the step of printing a second insulating layer on the core base over the second coil winding.
