20090241340 | METHOD OF MANUFACTURING HEAT SINK FOR MEMORY MODULE - A method of manufacturing a heat sink for a memory module is provided to remarkably improve its productivity by treating a plurality of heat sinks, which are arranged at a pre-determined interval, as a single body in detaching, painting and adhesive pad adhering steps to reduce a manufacturing cost, and improve its merchantability by interrupting direct contact between the heat sinks to prevent scratch of the heat sinks. The method of manufacturing a heat sink for a memory module comprises cutting and detaching the heat sink from a metal plate coil by using a press device. The heat sinks are connected to a heat sink molded sheet at a pre-determined interval through a bridge, and are detached from the heat sink molded sheet by the press device. After the cutting and detaching steps, the heat sink molded sheet ( | 10-01-2009 |
