PCB component and method for manufacturing voltage regulator module

Abstract

A PCB component is disclosed and includes a PCB and an inductor. The PCB includes a top surface and a bottom surface opposite to each other. The inductor includes a magnetic core, a winding, an upper surface and a lower surface opposite to each other. The winding runs through the magnetic core, and the winding forms an upper outlet terminal on the upper surface and a lower outlet terminal on the lower surface. The inductor is embedded in the PCB, the top surface is spatially corresponding to the upper surface, the bottom surface is spatially corresponding to the lower surface, a plurality of conductive layers are respectively disposed above the upper surface and below the lower surface, an upper welding position is disposed on the top surface and electrically connected to the upper outlet terminal, and a lower welding position is disposed on the bottom surface and electrically connected to the lower outlet terminal. The upper welding position is electrically connected to a power device and configured to transmit an input electrical signal, the lower welding position is electrically connected to an external circuit board and configured to transmit an output electrical signal, and the power device, the PCB component and the external circuit board are stacked vertically in sequence. Electrical connections between the power device and the upper welding position, and between the lower welding position and the external circuit board are implemented through one reflow welding process to form a voltage regulator module.
