Method for forming laminate and laminating device
A surface of a laminate base body including a projection is caused to penetrate at least a film-shaped laminating body and surely laminated by a simple configuration, and a laminate thereof is formed at a uniform thickness without an occurrence of voids. A laminating device is provided with a heating unit configured to heat at least an insulating resin film; an upper plate and a lower plate configured to be capable of opening and closing, and configured to form a chamber that becomes sealed upon closing; a receiving member having an elasticity and disposed on the upper plate; an elastic membrane body disposed on the lower plate; a vacuuming unit configured to vacuum inside of the chamber; and a compressing unit configured to bloat the elastic membrane body.
1. A method for forming a laminate by layering a laminate base body including a projection and a film-shaped laminating body, and heating and compressing the same so that the projection of the laminate base body completely penetrates at least the film-shaped laminating body, the method comprising:
layering the laminate base body and the film-shaped laminating body with each other by causing a side of the laminate base body on which the projection is formed to oppose the film-shaped laminating body;
disposing the layered laminate base body and film-shaped laminating body between a receiving member having an elasticity and an elastic membrane body so that the film-shaped laminating body opposes the receiving member and the laminate base body opposes the elastic membrane body; and
compressing the laminate base body and the film-shaped laminating body between the elastic membrane body and the receiving member by bloating the elastic membrane body in a state in which at least a space between the laminate base body and the film-shaped laminating body is vacuumed,
wherein:
the receiving member is made of a rubber material having heat resistivity;
the elastic membrane body is made of a rubber material having heat resistivity and is made to bloat outward by compressed air; and
a rubber member having a hardness that is harder than a hardness of the elastic membrane body is disposed on the surface of the receiving member.

wherein:
the receiving member is made of a rubber material having heat resistivity;
the elastic membrane body is made of a rubber material having heat resistivity and is made to bloat outward by compressed air; and
a rubber member having a hardness that is harder than a hardness of the elastic membrane body is disposed on the surface of the receiving member.
3. The method for forming a laminate according to claim 1 , wherein:
the laminate base body is mounted on a carrier film,
the layered laminate base body and film-shaped laminating body are conveyed between the receiving member and the elastic membrane body, and
the elastic membrane body compresses the laminate base body and the film-shaped laminating body via the carrier film toward the receiving member.
