Abstract: An amorphous powder core and a manufacturing method thereof are provided to process the amorphous powder at a low pressure by increasing the coupling between powders by forming a rough surface on the amorphous powder. An amorphous powder is formed by curing the powder at a high speed. Copper is coated on the amorphous powder surface. The amorphous powder with the coated copper is oxidized, so that the copper oxide is formed on the surface thereof. An amorphous powder core is obtained by forming the amorphous powder with the copper oxide. The copper is applied on the amorphous powder with a thickness less than 1 um by using an electroless plating scheme. The oxidation of the electroless plating device is performed at a temperature higher than 400 degrees centigrade for less than 60 minutes.
