Title:
METHOD FOR MANUFACTURING RADIATING MEMBER FOR ELECTRONIC EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2002/077303
Kind Code:
A1
Abstract:
A method for manufacturing a radiating member for electronic equipment comprising a composite material composed of a matrix metal containing Al as a primary component and SiC particles dispersed therein, which comprises a charging step of charging a SiC powder into a mold, a preheating step of preheating the mold after the charging step to a preheating temperature which is not lower than the melting point of the matrix metal and is lower than a reaction starting temperature at which a melt of the matrix metal starts to react with SiC particles in the SiC powder, and a melt pouring step of pouring a melt of the matrix metal having a temperature not lower than the melting point thereof and lower than the above reaction starting temperature to the mold after the preheating step and applying a pressure to thereby impregnating the SiC powder with the melt. The method allows the prevention of the formation of a substance having a low thermal conductivity during the above melt pouring step, while securing the impregnation of a SiC powder with a molten metal, due to the use of a melt pouring temperature and a preheating temperature which are both not lower than the melting point of the metal and lower than the reaction starting temperature defined above.
