1. A method for implementing enhanced low loss, thin, high performance flexible circuits performed by a processor, said method comprising:
said processor performing the steps of: receiving a plurality of predefined values including predefined layout, spacing and density of conductor, signal trace construct, shape and feature values for each signal layer in a flexible circuit; performing volumetric calculations using the predefined values for each signal layer in the flexible circuit; and responsive to said volumetric calculations, characterizing a respective adjacent adhesive layer for each signal layer providing an optimized adjacent adhesive layer; and wherein characterizing said respective adjacent adhesive layer for each signal layer providing said optimized adjacent adhesive layer includes strategically reducing an amount of adhesive residing within a signal trace geometry cross section and providing an increased thickness of an electrical insulator polyimide layer having a lower dissipation and dielectric properties, lower coefficient of thermal expansion (CTE), providing a reduced overall cross sectional thickness for the flexible circuit.
