CIRCUIT BOARD AND METHOD FOR MANUFACTURING SAME

摘要

Disclosed is a circuit board with excellent durability wherein a liquid crystal polymer is used for an insulating sheet and embrittlement of the liquid crystal polymer film is suppressed. Also disclosed is a method for manufacturing such a circuit board. Specifically disclosed is a method for manufacturing a circuit board which is characterized in that a liquid crystal polymer film is used as at least one of the surface sheets among the insulating sheets constituting the circuit board. This method is further characterized in that a fluorine-containing porous film is used as a releasing material when the liquid crystal polymer film is subjected to thermal compression bonding. A circuit board manufactured by such a method is excellent in durability.
