DEVICE FOR PRODUCING SEALING RESIN SHEET AND METHOD FOR PRODUCING SEALING RESIN SHEET

摘要

The present invention enables inexpensive production of a sealing resin sheet for insulated sealing of a plurality of electrical components mounted onto a substrate, and enhanced precision in the thickness of the sealing resin sheet. A device (30) for producing a sealing resin sheet is provided with: a molding die (40) for molding a sealing resin sheet (11) from a resin body (22); heating mechanisms (33A, 33B); a vacuum mechanism (38); and a pressurizing mechanism (34). The molding die (40) comprises: a pair of pressing plates (43, 45); a rigid body plate (44) for setting the thickness of the sealing resin sheet (11); and an elastic member (48). The elastic member (48) is thicker than the rigid body plate (44) and can be deformed by a pressing force coming from the pressing plate (45). The resin body (22) is stretched by pressing but is dammed between a deformed elastic member (28) and the pressing plate (45), and thus the resin body is prevented from leaking to the outside of the molding die (40).
