Speedstack Flex flex-rigid PCB stackup design tool allows PCB fabricators and OEM engineers to create and document flex-rigid PCB layer stackups using the Speedstack family of PCB stackup design tools.

It allows OEM designers to create an accurate and efficient flex-rigid PCB stackup in minutes, with error-free documentation for tighter control over the finished board. On the other hand, for PCB fabricators, Speedstack Flex provides the flexibility to quickly calculate the possible impact of substituting alternative materials to improve manufacturability and reduce cost while maintaining the specified parameters and performance of the board.

 Main Features

  • Mesh / Crosshatch ground planes
  • Internal Coverlays
  • Doublets - provides for situations where two or more flexi cores are present with an air gap in between.
  • Definable colours per material
  • Powerful stack browser / search option
  • High quality error-free documentation

XFE Cross Hatch Flex Enhancement

Polar has produced an alternative approach to modeling crosshatch using a proprietary technique, XFE (Crosshatch Flex Enhancement) this technique uses Polar's 2-D field solvers but uses a unique algorithm to correct for the effects of flex over a wide range of typical controlled impedance structures.

This approach has enabled solvers to model more closely the effects of a wide variety of crosshatch geometries. The XFE option, applicable to both Polar’s Si8000 lossless transmission line impedance solver and to the lossless mode of the Si9000 frequency dependent, lossy transmission line field solvers allows for configuration of hatch pitch (HP) and width (HW) as shown in the above graphic

Main Benefits of XFE

  • Reduces prototype turns when producing impedance controlled flex PCB
  • Provides modeling for controlled impedance lines with crosshatch or mesh ground returns
  • Modeling is based on proven Polar BEM solver
  • Available as an option for Si8000m and Si9000e for all lossless transmission lines
  • Useful for any PCB type deploying meshed / crosshatched return planes e.g. interposers
