Abstract: A magnetic component is disclosed and includes a circuit board and a magnetic core set. The circuit board includes two through holes passing through a first surface and a second surface thereof. The magnetic core set includes an upper magnetic cover and a lower magnetic cover disposed on the first surface and the second surface, respectively. The upper magnetic cover includes two magnetic columns connected to the lower magnetic cover through the two through holes. The upper magnetic cover is thermally coupled to a heat dissipation device, and a volume of the upper magnetic cover is greater than that of the lower magnetic cover. A thermal resistance defined from the upper magnetic cover to the heat dissipation device is smaller than that defined from the lower magnetic cover to the heat dissipation device. It helps to make the overall heat distribution of the magnetic component more uniform.

Abstract: A substrate-fastening device and a substrate-assembling structure are disclosed. The substrate-fastening device includes a base and a fastening component. The base correspondingly carries a substrate including a perforation. The fastening component is disposed on the base, corresponds to the perforation, and includes a supporting portion, a positioning portion, a resin-attaching portion, an end portion and a fixation resin. The supporting portion is disposed on the base to support the substrate. The positioning portion is disposed on a supporting surface of the supporting portion and extended along the perforation. The resin-attaching portion is extended along the perforation. The end portion is connected to the positioning portion through the resin-attaching portion. The fixation resin is disposed around the resin-attaching portion and connected between the end portion and the positioning portion. The fixation resin covers the second surface adjacent to the perforation, and fills the gap between the resin-attaching portion and the perforation.

Abstract: A power module includes a power source module and a metallic heat-dissipation substrate. The power source module has an input pin and an output pin soldered on and electrically connected with a system board and includes a printed circuit board. The printed circuit board has a first surface and a second surface. At least a heat-generating component is disposed on the second surface. The metallic heat-dissipation substrate has a first surface and a second surface opposite to each other. The first surface has at least a fixing position and at least a heat-dissipating position. The fixing position is directly or indirectly connected with the second surface. A gap accumulated by tolerances is existed between the heat-dissipating position and the heat-generating component. A gap-filling material is filled into the gap. The second surface and the system board are soldered with each other. Therefore, the heat-dissipation efficiency is enhanced.
