Abstract
A compression bonding device has a dam member so that when a pressing head is pressed against an object to be pressed, the bonding part is surrounded by the dam member. Thus, even if the surface of the bonding part bulges by pressing, the bulging part is stopped by the dam member and the surface of the bonding part does not horizontally extend. As a result of the absence of horizontal extension of the bonding part, electric components of the object to be pressed are not subjected to a force that horizontally moves the electric components and the electric components are vertically pressed downward and connected to the terminals of the substrate. Thus, an electric device having high connection reliability is obtained.
Claims5
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.
