Abstract: A method of manufacturing a heat dissipation sheet including preparing a preliminary sheet including a matrix-forming component, a crosslinking agent, and a heat dissipation filler, and crosslinking the matrix-forming component included in the preliminary sheet and thus obtaining a heat dissipation sheet. The heat dissipation sheet manufactured has remarkably excellent heat dissipation properties because it contains a high content of heat dissipation filler. Due to the material properties of the matrix-forming component and the crosslinking of the matrix-forming component and the resulting matrix formation, the occurrence of cracking, shrinkage, pore formation, thickness change, and the like is minimized or prevented, and excellent flexibility can be attained. Moreover, since processability is improved through processes such as cooling when manufacturing the heat dissipation sheet, productivity is excellent, and the sheet can be suitable for mass production.

Abstract: Provided is an organic thin film forming apparatus, an organic thin film forming method, and a method of manufacturing an organic thin film device using the same, in which an organic light-emitting layer (photoactive layer) and/or an electron transport layer can be formed on a substrate when an organic light emitting diode (OLED) or an organic solar cell is manufactured. The organic thin film forming apparatus includes: a solution spray unit for spraying a solution on a substrate; and a hot gas spray unit for spraying a hot gas onto fine liquid droplets that have been sprayed from the solution spray unit and that are in flight, to thereby evaporate a solvent contained in the fine liquid droplets.

Abstract: Provided herein is a magnetic sheet. The magnetic sheet according to one embodiment of the present invention includes a magnetic layer formed of crushed pieces of a magnetic body to improve flexibility of the magnetic sheet, and a thin film coating layer formed on at least one surface of the magnetic layer to maintain the magnetic layer in a sheet shape and buffer an external force applied to the crushed pieces of the magnetic body. According to the present invention, since the magnetic sheet is improved in mechanical strength properties, such as a tensile property, a bending property, and the like, to have significantly superior flexibility, degradation of physical properties, such as magnetic permeability and the like, caused by physical damage such as unintended cracks in the magnetic body provided in the magnetic sheet can be prevented even in the process of storing, transferring, and attaching the magnetic sheet to a target object and during usage of an electronic device provided with the target object to which the magnetic sheet is attached, and the magnetic sheet can be attached to a target surface of the target object with a superior adhering force even when a stepped portion is present at the surface, and at the same time, the magnetic sheet can block the influence of a magnetic field on parts of a portable terminal device or a human body of a user using the portable terminal device, significantly increase transmission and reception efficiencies and distances of a data and/or wireless power signal, and maintain the above-described performance for a long period of time, such that the magnetic sheet can be widely used in various portable devices such as mobile devices, smart appliances, devices for the Internet of Things, and the like.

Abstract: A housing for repeater having an accommodation part accommodating therein a device for repeating an RF signal, and at least a portion of the housing is implemented with heat dissipation plastic having, at a frequency of 28 GHz, a relative permittivity of less than or equal to 4 and a thermal conductivity of greater than or equal to 3 W/mK. Accordingly, as the housing has a high heat dissipation performance against high heat generated from various types of devices provided inside the repeater for transmitting and receiving a signal in a high frequency band and minimizes the interference of transmission and reception of the signal in the high frequency band, the housing can be widely used as a housing for repeater in the mobile communication field or the like using a signal in a high frequency band.
