  • Patent number: 6313402
    Abstract: A metallic or an electrical trace having a terminus and a stress relief bend formed in the trace adjacent the terminus. The electrical trace may have a portion carried by a flexible substrate to form a flexible circuit. The stress relief bend may be free floating and extend from the flexible substrate or may be encapsulated by the flexible substrate. The electrical circuit and the flexible circuit each have a generally planar portion extending in the X and Y axis, with the stress relief bend projecting into the Z axis. This allows electrical traces to be spaced with a very narrow pitch because the stress relief bend does not consume any valuable real estate on the flexible circuit or the substrate to which the electrical trace is applied.
