Abstract
A flexible circuit suitable for high density applications and having a long flexural life is disclosed. A thin film metallic ground plane deposited on a dielectric substrate electrically shields the conductor traces in the flexible circuit and eliminates cross-talk between conductor traces without reducing the flexibility or the flexural life of the flexible circuit.
