Silicone sheet and mounting method using the same

Abstract

A silicone sheet 1 of the present invention is a silicone sheet that is at least one selected from a silicone gel sheet and a silicone putty sheet. The silicone sheet has a Shore 00 hardness of 75 or less. The silicone sheet is cut in a thickness direction and cut faces 5 a - 5 m and 6 a - 6 f of the silicone sheet are adjacent to each other without gap. The cut faces of the silicone sheet are non-tacky, and the silicone sheet is separable at the cut faces. Preferably, the cut faces have a tackiness of 0.6 N or less based on a tackiness checker. The mounting method of the present invention is a method of mounting the above silicone sheet by pick and place mounting using an automatic mounting machine.

What is claimed is: 
     
         1 . A silicone sheet that is at least one selected from a silicone gel sheet and a silicone putty sheet,
 wherein the silicone sheet has a Shore 00 hardness of 75 or less,   the silicone sheet is cut in a thickness direction and cut faces of the silicone sheet are adjacent to each other without gap,   the cut faces of the silicone sheet are non-tacky, and   the silicone sheet is separable at the cut faces.   
     
     
         2 . The silicone sheet according to  claim 1 , wherein the cut faces have a tackiness of 0.6 N or less based on a tackiness checker. 
     
     
         3 . The silicone sheet according to  claim 1 , wherein the silicone sheet has a heat conductivity of 0.5 W/mK or more. 
     
     
         4 . The silicone sheet according to  claim 1 , wherein cover films are disposed on upper and lower surfaces of the silicone sheet. 
     
     
         5 . The silicone sheet according to  claim 1 , wherein the cut faces exhibit non-tackiness by at least one selected from an application of a remover and high crosslinking. 
     
     
         6 . A method of mounting a silicone sheet that is at least one selected from a silicone gel sheet and a silicone putty sheet by pick and place mounting using an automatic mounting machine,
 wherein the silicone sheet has a Shore 00 hardness of 75 or less,   the silicone sheet is cut in a thickness direction and cut faces of the silicone sheet are adjacent to each other without gap,   the cut faces of the silicone sheet are non-tacky, and   the silicone sheet is separable at the cut faces.   
     
     
         7 . The method of mounting a silicone sheet according to  claim 6 , wherein the cut faces have a tackiness of 0.6 N or less based on a tackiness checker. 
     
     
         8 . The method of mounting a silicone sheet according to  claim 6 , wherein the silicone sheet has a heat conductivity of 0.5 W/mK or more. 
     
     
         9 . The method of mounting a silicone sheet according to  claim 6 , wherein cover films are disposed on upper and lower surfaces of the silicone sheet. 
     
     
         10 . The method of mounting a silicone sheet according to  claim 6 , wherein the cut faces exhibit non-tackiness by at least one selected from an application of a remover and high crosslinking.
