Method and apparatus for reducing crosstalk and signal loss in flexing interconnects of an electrical lead suspension

摘要

A method and apparatus for reducing crosstalk and signal loss in an electrical interconnect is disclosed. The electrical interconnect includes a laminate. A plurality of signal traces and a subsequent plurality of traces are in a first formed layer of the laminate. The subsequent plurality of traces may be signal traces or power traces. The laminate has a dielectric layer between the first formed layer and a second formed layer. A plurality of serpentine patterns are in the second formed layer of the laminate. The plurality of serpentine patterns is separated from subsequent patterns. The plurality of serpentine patterns supports the plurality of signal traces and the subsequent plurality of patterns supports the subsequent plurality of traces. The supporting of the plurality of signal traces separate from the subsequent plurality of traces reduces write-to-read crosstalk and signal loss.
