Method of manufacturing heat sink for memory module

Abstract

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 ) is painted, an adhesive pad ( 5 ) is adhered to the painted heat sink molded sheet ( 10 ), and the heat sink is separated by cutting the bridge ( 12 ).

1 . A method of manufacturing a heat sink for a memory module, the method comprising cutting and detaching the heat sink from a metal plate coil by using a press device,
 in which the heat sinks  11  are connected to a heat sink molded sheet  10  at a pre-determined interval through a bridge  12 , and are detached from the heat sink molded sheet  10  by the press device.   
   
   
       2 . The method as claimed in  claim 1 , further comprising
 painting the heat sink molded sheet  10  after the cutting and detaching steps;   adhering an adhesive pad  5  to the painted heat sink molded sheet  10 ; and   separating the heat sink by cutting the bridge  12 .   
   
   
       3 . The method as claimed in  claim 1 , wherein the bridge  12  of the heat sink molded sheet  10  consists of first bridges  12   a  connected to left and right ends of the heat sink  11 , and second bridges  12   b  connected to the first bridges  12   a  to maintain an arranging interval of the heat sinks  11 . 
   
   
       4 . The method as claimed in  claim 1 , wherein in the cutting and detaching steps, a cut line  12   c  is formed on each front end of the first bridges  12   a , and through-holes  12   d  are formed on the second bridge  12   b  at a predetermined pitch.
