METHOD FOR MANUFACTURING LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide a laminate having a small size change rate suitable for a flexible board material. SOLUTION: A method for manufacturing the laminate comprises the step of laminating a plurality of materials to be laminated each containing a heat fusion bondable material to be laminated and a metal material by a heating and pressurizing molding machine. The method further comprises the steps of disposing a protective material between a pressurizing surface of the machine and the material to be laminated, heating and pressurizing molding the material at 200 deg.C or higher, and releasing the material from the laminate after cooling. In this method, a tension operating at the material to be laminated until the time before the materials are laminated by the machine is set to a necessary minimum limit for stably linearly moving the material, and the tension of the metal material is set to three times as large as that of the material to be laminated.
