Patent ID: 8053352

Claim:
A method for forming a mesh reference structure comprising the steps of: forming a mesh power and ground reference plane including a grid of mesh traces; said mesh traces having selected thickness and width dimensions effective for reference current-flow distribution for associated signal traces; providing said mesh power and ground reference plane spaced apart from said associated signal traces; and depositing an electrically conductive coating selectively formed of a selected metal and having a selected thickness on said mesh power and ground reference plane to fill the mesh electrical holes in said mesh power and ground reference plane substantially without affecting mechanical flexibility of the mesh reference structure; said electrically conductive coating covering an entire mesh surface of said mesh power and ground reference plane and eliminating a line-of-sight path between associated signal traces and reducing cross-talk; and wherein depositing said electrically conductive coating includes depositing said electrically conductive coating having a thickness of about one micrometer (10 −6 meter).
