Hello,

I can to create 9x9mm Pitch 0.65mm 169 pins BGA package with kicad-3d-models-in-freecad?

Hi Javier, here some tips:

  1. get the drawing details
    http://cache.freescale.com/files/shared/doc/package_info/98ASA00628D.pdf
  2. edit the parameters of the BGA in
    https://github.com/easyw/kicad-3d-models-in-freecad/blob/master/cadquery/FCAD_script_generator/BGA_packages/cq_parameters.py
  3. launch the script
    (have a read at the Readme.adoc)

PS do you have also the footprint? I think this could be easily done by the footprint wizard for BGAs

Hello maui,

Yes, I have done the footprint with that document. 98ASA00628D

Thanks

when you have done also the 3d models, you may think to PR to the kicad libraries and my 3d script generators repo :smiley:

Here the information on how to share 3d models:
new packages 3d repo add the step and wrl file to this repo as well as a credits file where you describe how the models have been created. (via a scipt or by using the standard tools of freecad)
current modules/packages3d directory of the kicad lib repo Add the files to this repo as well. (Currently only this repo is used by kicad. This will change in the near future.)

Source files should go here Use this repo do share your source files. (If you use the scripts by @maui, you don’t need to share source files in this repo. Just give the correct information in the credits file.)

Ok, thanks,

When I can I merge the pull request. I have other models to create, Audio/Video TX + PA, interesting for Drones FPV.

I seem to have problem getting this file (BGA-169_9x9X1.15mm_Pitch0.65mm.kicad_mod). Is it available somewhere else?
