Abstract
A film-shaped adhesive application apparatus includes a supply reel retainer for mounting a film-shaped adhesive supply reel used to wind into a roll shape a film-shaped adhesive 1 comprising a base film and an adhesive layer formed thereon, thermocompression bonding means for thermocompression-bonding the film-shaped adhesive drawn from the film-shaped adhesive supply reel to an adherend, and a winding reel retainer for mounting a winding reel used to wind the base film of the thermocompression-bonded film-shaped adhesive, and further temperature control means (thermal shield plate, cooler, or the like) for controlling the film-shaped adhesive supply reel mounted on the supply reel retainer at a prescribed temperature.
Claims6
A method for applying a film-shaped adhesive comprising:
- supplying a film-shaped adhesive from a film-shaped adhesive supply reel;
- controlling an amount of adhesive squeezed out of the film-shaped adhesive while the film-shaped adhesive is on the film-shaped adhesive supply reel in a range of from about 3 μm to about 11 μm;
- the controlling comprising controlling a temperature of the film-shaped adhesive supply reel with a temperature control device to be from 10° C. to 30° C., the controlling of the temperature also preventing formation of condensation on a surface of the film-shaped adhesive;
- bonding an adhesive layer of the film-shaped adhesive to an adherend by thermocompression bonding;
- and
- removing a base film of the film-shaped adhesive from the adhesive layer, following the bonding,
- wherein the bonding is achieved by a film-shaped adhesive application apparatus, and the film-shaped adhesive application apparatus comprises:
- a supply reel retainer for mounting the film-shaped adhesive supply reel used to wind into a roll shape the film-shaped adhesive composed of a base film and the adhesive layer formed thereon, so that a reel tension of the film-shaped adhesive is 100 g or less,
- a thermocompression bonding device, the thermocompression bonding device thermocompression-bonding the film-shaped adhesive drawn from the film-shaped adhesive supply reel onto the adherend,
- a winding reel retainer for mounting a winding reel used to wind the base film of the thermocompression-bonded film-shaped adhesive, and
- the temperature control device.
