Abstract:
1. A compression bonding device comprising: a pedestal; a dam member; a pressing head; a protective film, the protective film being deformable and releasable from an anisotropic conductive film; and a heater with which the anisotropic conductive film is heated, the pressing head and the pedestal being movable relative to one another to press an object to be pressed placed on a mounting face of the pedestal with the pressing head, wherein the pressing head has a head body and a pressing rubber which is placed in the head body, the protective film is placed on the object placed on the pedestal, the pressing rubber is configured to press the object while being in contact with the protective film, the dam member having a surface level that extends beyond the pressing rubber is placed around the pressing rubber while the object is pressed, and a lateral flow of the pressing rubber due to deformation of the pressing rubber is stopped by the dam member when the object is pressed with the pressing rubber, wherein said protective film extends along either a side surface of the pedestal or extends along a side surface of said dam member when the components are pressed.
