XFE (Crosshatch Flex Enhancement) technique couples novel 2-D field solvers with a unique algorithm to correct for the effects of flex over a range of typical controlled impedance structures. Enables solvers to more closely model the effects of a wide variety of crosshatch geometries. Permits configuration of hatch pitch (HP) and width (HW). Reduces prototype turns when producing impedance controlled flex PCBs. Models controlled impedance lines with crosshatch or mesh ground returns. Is said to be for any PCB type deploying meshed/cross-hatched return planes (e.g., interposers). Is for Si8000 and Si9000 field solvers.
