Substrate-embedded transformer with improved isolation

Abstract

An embedded-core device including a substrate, a core embedded in the substrate, a winding arranged around the core, and a dummy pin in direct contact with the core and not in direct contact with the winding. A method of a manufacturing an embedded-core device includes providing winding pins and a dummy pin, inserting a core between the winding pins using the dummy pin such that the dummy pin is in direct contact with the core and not in direct contact with the winding pins, and sealing the core with resin.
