Abstract: The present disclosure relates to an electronic device, and more specifically, to an electronic device including a printed circuit board including a heat-generating element arranged on one surface thereof, and a heat transfer coin provided such that one surface of the heat transfer coin comes into contact with a portion of the other surface of the printed circuit board, opposite to the heat-generating element, so as to dissipate heat generated from the heat-generating element. Accordingly, the present disclosure provides an advantage of improving heat dissipation performance without increasing the thickness of the printed circuit board.

Abstract: A communication apparatus is provided to include an apparatus enclosure that includes a substrate seating surface and at least one or more connection grooves formed on the substrate seating surface, a first printed circuit board disposed on the substrate seating surface, a second printed circuit board disposed on the substrate seating surface on one side of the first printed circuit board, and at least one or more connectors disposed within the connection groove and configured to electrically connect the first printed circuit board and the second printed circuit board.

Abstract: The present invention relates to a signal shielding apparatus and an antenna apparatus including same, and in particular, comprises a shield cover which is stacked and disposed on a printed board assembly (hereinafter, abbreviated to “PBA”), in which a plurality of signal-related components are mounted on one side thereof to prevent leakage of a signal from the plurality of signal-related components, wherein a grooved shield cover seating groove is formed in one surface of the PBA, and an insertion end insertably seated in the shield cover seating groove is integrally formed in the other surface from among one surface and the other surface of the shield cover, the other surface facing the one surface of the PBA, thereby providing advantages in that an increase in the manufacturing cost may be prevented, EMI shielding may be facilitated, and heat dissipation performance may be significantly improved.

Abstract: A system for charging a battery for a vehicle may include a charging control device having a power factor correction circuit configured to convert an alternating current (AC) voltage of a charging apparatus into a direct current (DC) voltage, a DC-DC converter connected to the power factor correction circuit and configured to transform the DC voltage, a capacitor connected to an output terminal of the DC-DC converter, and a relay unit provided between the capacitor and the battery; and a control unit connected to the charging control device and configured to perform initial charging control in consideration of a capacitor voltage of the capacitor when the charging apparatus and the power factor correction circuit are connected by the control unit.
