Notes: 1)Take Connection Film out of the refrigerator or other storage without taking it out of its hermetic containers. Leave the Connection Film in the containers at room temperature for
2)Connection resistance: The table indicates a half of the resistance between neighboring circuits.
Current measured: 1mA. Includes the circuit resistances of the FPC and ITO glass.
3)Tack strength: Pre-bond an Connection Film sample to an ITO glass, peel its separator off, then tack s FPC to
it at room temperature. Then measure the tack strength of this sample.
4)Operating range: As per reliability tests using Hitachi’s test pieces.(This range varies according to the material used and external stress app
