Title:
耐熱性フレキシブル積層板の製造方法およびこれにより製造される耐熱性フレキシブル積層板
Document Type and Number:
Japanese Patent JP3534405
Kind Code:
B1
Abstract:
A method for manufacturing a heat resistant flexible laminate effectively enabling avoidance of not only visual defects but occurrence of dimensional changes, and a heat resistant flexible laminate are provided. In a process for laminating a heat resistant adhesive material and a metallic foil by thermal lamination, a film-like protective material is disposed between a pressurized surface and the metallic foil at the time of thermal lamination. At this time, coefficients of linear expansion in a temperature range of 200 degree C to 300 degree C of the heat resistant adhesive material and the protective material are within a range of a coefficient of linear expansion of the metallic foil +/- 10 ppm/degrees C. Thereby, occurrence of visual defects is not only effectively avoidable, but excellent dimensional change after etching may be exhibited.
