Method and Structure for Implementing Control of Mechanical Flexibility With Variable Pitch Meshed Reference Planes Yielding Nearly Constant Signal Impedance

摘要

A method and structure are provided for implementing flexible circuits of various electronic packages and circuit applications. A meshed reference plane includes a variable mesh pitch arranged for control of mechanical flexibility. A dielectric core separates a signal layer from the variable pitch meshed reference plane. An electrically conductive coating covers the surface of the variable pitch meshed reference plane yielding substantially constant signal impedance for the signal layer.
