Embodiment 1

[0043] First, endless belts (A, B, and C) having three types of compositions shown in "Table 1" were prepared for a continuous preparation test to compare durability time and 0.2% endurance. Through continuous operation under the heating temperature condition of 300°C, a double-belt pressing method is adopted to realize continuous preparation and testing. For the sheet, a polyimide-based film (manufactured by Ube Industries, Ltd. under the trademark UPILEX, 25 micrometers in thickness), and copper foil (manufactured by Nippon Denkai, Ltd., 18 micrometers in thickness) can be used.

Abstract

Provided is double belt pressing equipment and the like, which enable a flexible metal foil laminate with a good appearance to be stably formed, even if the flexible metal foil laminate is continuously manufactured over a long period of time. This double belt pressing equipment is fitted with an endless belt wherein 0.2% proof stress on condition of 300[deg.]C is 1,100 N / mm<SP>2< / SP>or more. Since this enables an increase in the durability of the endless belt and the securement of the surface smoothness of the endless belt, a scratch is prevented from being transferred to a product. Thus, theflexible metal foil laminate with the good appearance can be continuously manufactured.

Description

technical field [0001] The present invention relates to a double-belt press apparatus to be used for the preparation of laminates and a manufacturing method using such an apparatus. More particularly, it relates to a double-belt press apparatus for producing flexible metal foil laminates by thermocompression bonding multilayer polyimide films to metal foils, and the production using such apparatus method. Background technique [0002] A laminate prepared by bonding an aromatic polyimide film to a metal foil has been widely used as a substrate material of electronic components and the like. Among these laminates, the flexible metal foil laminate is a multilayer polyimide film (a high thermal resistance aromatic polyimide layer that has been laminated and integrally formed by a cast film forming method and a thermocompression bonded aromatic polyimide layer) A laminate prepared by thermocompressing a polyimide layer to a metal foil. Since no adhesive (epoxy resin, etc.) is ...
