It is advantageous to provide a material having a low dielectric constant (E(r)) for use as a dielectric layer between the signal and power planes of a printed circuit board. Normally, an epoxy laminating resin is used for the purpose of fabricating the several layers of a circuit board. As the E(r) goes down, the electrical performance of the circuitry, i.e., time delay, capacitance and coupled noise, is improved.
