Magnetic component with integrated component circuit board

摘要

A component printed circuit board is provided between a magnetic component and a main printed circuit board. The magnetic component includes a device such as an inductor or transformer and includes a bobbin for winding one or more coils and a magnetically permeable core. Terminal pins protrude from the bobbin toward the main printed circuit board and provide electrical connection between the magnetic component and the main printed circuit board. The component printed circuit board includes component vias positioned to accept one or more of the terminal pins allowing the terminal pins to be used for electrical connection to both the component printed circuit board and the main printed circuit board. One or more component traces or shielding layers are disposed on the component printed circuit board. Each component trace provides an electrical connection between two or more terminal pins passing through the component printed circuit board.
