Method for manufacturing a planar electronic device having a magnetic component
First Claim
1. A method for manufacturing a planar electronic device, the method comprising:
- applying a non-conductive fluid polymer to a lower side of a planar substrate, the substrate including a hole extending through the substrate between the lower side and an opposite upper side of the substrate;
curing the fluid polymer to form a solid centering layer on the lower side of the substrate, the centering layer extending across the hole along the lower side of the substrate;
loading a ferrite material body into the hole of the substrate through the upper side of the substrate such that the ferrite material body contacts the centering layer, the centering layer preventing the ferrite material body from moving beyond the lower side of the substrate;
embedding the ferrite material body in an encapsulating material that is deposited into the hole and around the ferrite material body; and
forming one or more conductive loops around the ferrite material body, wherein the ferrite material body is held within the substrate between the lower side and the upper side of the substrate by the encapsulating material.

Abstract
A method for manufacturing a planar electronic device includes applying a non-conductive fluid polymer to a lower side of a planar substrate. The substrate includes a hole extending through the substrate. The method also includes curing the fluid polymer to form a solid centering layer on the lower side of the substrate, with the centering layer extending across the hole along the lower side of the substrate. The method further includes loading a ferrite material body into the hole of the substrate through the upper side of the substrate, embedding the ferrite material body in an encapsulating material in the hole, and forming one or more conductive loops around the ferrite material body. The ferrite material body is held within the substrate between the lower side and the upper side of the substrate by the encapsulating material.
