A magnetic component provides both electrical interconnectivity and mechanical support between stacked circuit boards. The magnetic component includes a bobbin structure and a magnetically permeable core. The bobbin structure includes an upper bobbin pin rail and a lower bobbin pin rail. The upper bobbin pin rail includes one or more upper bobbin pins extending from the upper bobbin pin rail. Each upper bobbin pin may be adapted for soldering onto a first circuit board. At least one lower bobbin pin extends from the lower bobbin pin rail. Each lower bobbin pin may also be adapted for soldering onto a second circuit board, forming a circuit board assembly. Each soldered connection between a bobbin pin and a circuit board may provide an electrical connection between the circuit board and the magnetic component. Each soldered connection may also provide a mechanical attachment between a printed circuit board and the magnetic component. A conductive coil is positioned on the bobbin structure and may be connected to an upper or lower bobbin pin. The core is positioned near the conductive coil for providing an electrical connection between the circuit boards through magnetic coupling.
