Scripts - Intelligent Connection to Encore BGA

By the time you have finished with FA3ST you will have a complete package "shell" - die, wirebonds, fingers, rings, balls, fiducials and masks. But you still don't have:

  • vias
  • routing traces
  • tear drops
  • While it is certainly possible to do this within AutoCAD, many companies have invested in high end package design tools such as Xynetix Encore BGA and Cadence Advanced Package Designer. It would be ideal if one could transfer the entire package shell intelligently to one of these programs to do routing, DRC and manufacturing output.

    With our FA3ST script generators you can do this.

    FA3ST includes a script generator that automatically creates scripts for the ball array, die, power and ground rings, fiducials, solder mask, bond fingers and wire bonds.

    User Interface

    To start the script generator just use the FA3ST pulldown and select:
    Export Xynetix Scripts...

    Then check off the scripts you wish to generate. Each script is a simple ASCII file that can be sent to Encore BGA. Using the Import Script function you then transfer the information intelligently into Encore.

    Script Functions

    AutoCAD Entity Script Encore BGA Action
    Die Pads/Outline die.inp Open a new package for your die. Read in die.inp. save the package. You will use this package in your circuit design.
    bond fingers finger.inp After reading in the netlist use the finger.inp to add "intelligent" bondfingers (with wire). Encore rotates the bondfinger to align with the wire. Note: you must create the padstack in advance and also a special padstack for power/ground nets!
    Power Ring power.inp Import power.inp to get your power ring. Convert from figure to metal.
    Ground Ring ground.inp Load ground.inp. Convert from figure to metal.
    Fiducials fid.inp Load fid.inp. Convert from figure to metal.
    Solder Mask Openings smask.inp Load smask.inp. do not need to convert to metal.
    Die Flag dieflag.inp Load dieflag.inp. Convert from figure to metal.
