Abstract
A flexible circuit is presented having a flexing (cyclic bending) section of lower stiffness than adjacent parts of the circuit. The lower stiffness in the flexing section is achieved by reducing the thickness of the flexing section, either by omitting or removing some or all of the dielectric material of the flexible circuit in the flexing section, or by replacing conventional dielectric material in the flexing section with a polymer of lower modulus of elasticity.
