摘要： The present invention provides a method for manufacturing a thin film foil, wherein a metal thin film layer is formed on a base substrate through a vacuum deposition process to form an ultra-thin film foil having a thickness of 5 μm or less, preferably 2 μm or less. The provided method for manufacturing a thin film foil comprises the steps of: preparing a base substrate having release properties; preparing a metal raw material; vacuum-depositing the metal raw material on the base substrate to form a metal layer on the base substrate; and separating the base substrate from the metal layer to form a thin film foil, wherein one of a BeCu alloy, a Cu—Ag—Cr ternary alloy, an Ag alloy, a CuMo alloy, and a CuFeP alloy is prepared as the metal raw material.

摘要： Electromagnetic wave shielding material including a conductive fiber web with multiple pores and a heat dissipation unit provided in at least some pores that is so excellent in flexibility, elasticity, and creasing/recovery that it can be changed in shape freely and brought in complete contact with a surface where the material is to be disposed even if the surface has a curved shape, uneven portions, or stepped portions, thus exhibiting excellent electromagnetic wave shielding performance and prevent deterioration thereof despite various shape changes. Since heat dissipation performance is excellent, heat generated in an electromagnetic wave source can be rapidly conducted and released. Even if parts are provided in a narrow area at high density, the material can be brought in close contact with mounted parts by overcoming a tight space between the parts and a stepped portion. The invention is employed for light, thin, short, and small or flexible devices.

摘要： An Fe-based soft magnetic alloy is provided. The Fe-based soft magnetic alloy can be represented by empirical formula FeaBbCcCud, and in the empirical formula, a, b, c and d are atomic percent (at %) of the corresponding element and are respectively 78.5≤a≤86, 13.5≤b+c≤21 and 0.5≤d≤1.5. The alloy has a high saturated magnetic flux density, excellent high frequency characteristics and low coercivity, and thus greatly facilitates the development of use as high performance/high efficiency small/lightweight parts. Since manufacturing costs are very low and the components contained in an alloy are easily controlled in an alloy manufacturing process, thereby enabling mass production of the alloy, the present invention can be widely applied as magnetic parts of electric and electronic devices such as a high power laser, a high frequency power supply, a high-speed pulse generator, an SMPS, a high-pass filter, a low-loss high frequency transformer, a fast switch and wireless charging.

摘要： 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.
