Zusammenfassung: | PURPOSE:To enhance the adhesive of a copper foil with a prepreg in a circuit board, in which the prepreg, in which a cloth-shaped base material is impregnated with a fluororesin, and the copper foil are bonded. CONSTITUTION:A composite body, in which the non-baked thin layer of a fluororesin is formed onto the mat surface of a copper foil, is prepared, and the fluororesin non-baked thin layers of said composite body are superposed on both surfaces of a fluororesin prepreg so as to be faced oppositely, and heated and pressed and unified. |
