Each of the first and second lead portions may be spaced apart from the third lead portion by a predetermined distance. | 2015-01-22 |
20150021083 | ELECTRONIC DEVICE AND MANUFACTURING METHOD THEREOF - An electronic device comprising a first magnetic powder; a second magnetic powder, wherein the mean particle diameter of the first magnetic powder is larger than the mean particle diameter of the second magnetic powder, the Vicker's Hardness of the first magnetic powder is greater than the Vicker's Hardness of the second magnetic powder by a first hardness difference, and the first magnetic powder mixes with the second magnetic powder; and a conducting wire buried in the mixture of the first magnetic powder and the second magnetic powder; wherein by means of the first hardness difference of the first magnetic powder and the second magnetic powder, the mixture of the first magnetic powder and the second magnetic powder and the conducting wire buried therein are combined to form an integral magnetic body at a temperature lower than the melting point of the conducting wire. | 2015-01-22 |
