Title:
METHOD AND APPARATUS FOR MANUFACTURING THERMAL CONDUCTIVE SHEET
Document Type and Number:
Japanese Patent JP2020192694
Kind Code:
A
Abstract:
To provide a method for manufacturing an electric insulating sheet improved in thermal conduction performance.SOLUTION: A method for manufacturing a bellows-like sheet VS containing a filler F having thermal conduction anisotropy comprises: a bellows-like sheet forming step of forming a bellows-like sheet VS in which a plurality of mountain folds and valley folds are alternately continuous; and a shaping step of compressing the bellows-like sheet in a direction in which an interval between the mountain folds or the valley folds becomes small to shape the bellows-like sheet into a flat plate shape. The bellows-like sheet forming step includes a thin film forming step of forming a thin film TF by attaching a synthetic resin material containing the filler F to a surface of a predetermined molding die; and a solidification step of solidifying the synthetic resin material.SELECTED DRAWING: Figure 3
