  • Publication number: 20240098880
    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.

  • Publication number: 20240088553
    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.

  • Publication number: 20150159265
    Abstract: Provided herein is a metal chalcogenide thin film and a method for preparing the metal chalcogenide thin film, the method including forming a metal layer on a substrate; and forming a metal chalcogenide thin film by inserting the substrate into a chamber for low temperature vapor deposition, injecting a gas containing chalcogen atoms and an argon gas into the chamber, generating a plasma such that chalcogen atoms decomposed by the plasma chemically combine with metal atoms constituting the metal layer to form the metal chalcogenide thin film.
