DuPont™ DuPont™ Kapton® EN-A, EN-C, EN-Y, and EN-Z are the premium performance polyimide films for use as a dielectric substrate for chip on film, flexible printed circuits and high density interconnects. These polyimide films show superior surface quality, high modulus, and excellent CTE control, which makes them preferred dielectric films or very fine pitch circuity and next generation IC packaging application.

Applications include:

• Chip on Film (COF)
• Metallized FPC
• Semiconductor
• Package TFT
