Abstract:
1. A molecularly flexible dielectric electronic substrate having a modulus of elasticity less than about 500,000 psi, said molecularly flexible dielectric electronic substrate comprising: a first layer of molecularly flexible dielectric adhesive having a modulus of elasticity less than about 500,000 psi, having a glass transition temperature less than about 0° C., and having the ability to withstand soldering at a temperature of about 220° C.; a metal foil on a first surface of said first layer of molecularly flexible dielectric adhesive, wherein said metal foil is patterned to define a pattern of electrical conductors having a plurality of contact sites for receiving a plurality of contacts of an electronic device; and a plurality of electrically conductive vias through said first layer of molecularly flexible dielectric adhesive, said plurality of electrically conductive vias being in a pattern for providing electrical connection between ones of said pattern of electrical conductors on the first surface of said first layer of molecularly flexible dielectric adhesive and corresponding contact sites on a second surface of said first layer of molecularly flexible dielectric adhesive opposite the first surface thereof.
