ABSTRACT:
A flexible circuit board providing the dual benefits of flexibility and shielding against incidental radiation. The flexible, shielded circuit board includes a number of electrical conductors disposed in a substrate, substantially parallel to opposing surfaces of the substrate. Electrical shield layers in the form of a mesh or grid are disposed on the substrate surfaces and are preferably formed by screen printing a conductive layer on each side of the substrate. A repeating pattern of shield conductors, shield conductor vertices, and voids in the shield layer through which the substrate is exposed is thus created on either side of the substrate.
