A method and related configuration for attenuating high-frequency noise
that may appear on power planes in printed circuit boards. In one
embodiment, the noise attenuation means of the present invention involves
applying a lower conductivity material between the conductive and
dielectric layers within a printed circuit board. High-frequency noise is
then attenuated by the skin effect. In another embodiment, the low
conductivity material is applied between the power plane and dielectric
layer within the printed circuit board. The low conductivity material may
be a material, such as nickel or lead, having an electrical conductivity
ranging between about 1.times.10.sup.4 mhos/m and 5.8.times.10.sup.7
mhos/m for layers having a thickness of about 2 mils.
