<P>PROBLEM TO BE SOLVED: To greatly suppress displacement also in electrode joining of a narrow pitch by more greatly reducing unevenness of sheet surfaces which contacts COF than conventional products by carrying out laminate unification of the glass cloth which is carried out flat or opening processing, since in the conventional glass cloth, displacement may arise in the electrode joining of narrow pitch, since an intersection of warp and weft is especially strongly forced on a flexible printed circuit board during thermocompression bonding, and in a single layer thermally conductive rubber sheet which does not contain the glass cloth, there is a tendency for displacement to tend to take place especially at the end of flexible printed circuit board, since easily deformed compared with a glass cloth content article. <P>SOLUTION: The silicone rubber sheet for thermocompression bonding is obtained by laminate unification of the glass cloth which is carried out flat or opening processing in the thermally conductive silicone rubber layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
