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.
Claims9
A flexible, shielded circuit board comprising:
- a substrate having first and second opposing substantially planar surfaces and one or more conductors disposed in the substrate;
- and
- first and second shield layers comprised of electrically conductive material respectively disposed on said first and second planar surfaces, said first and second shield layers each having a mesh pattern of voids and conductive regions, said voids being defined by said conductive regions;
- the mesh pattern of said first shield layer being offset from the mesh pattern of said second shield layer.
