METHOD FOR PRESS PROCESSING OF PRINTED BOARD USING RELEASE FILM

摘要

PROBLEM TO BE SOLVED: To provide a method for the press processing of a printed board excellent in the releasability with the printed board or the anti-staining properties against the printed board. SOLUTION: In the method for the press processing of the printed board using a release film, a transfer layer transferable to the printed board is provided on at least one surface of the release film. The glass transition temperature Tg (°C) of the resin constituting the transfer layer, a release film disassembling temperature Tk (°C) after press processing and the flow beginning temperature Tf (°C) of the adhesive resin arranged between boards show a relation represented by the formula: Tf≥Tg≥Tk.
