datasheet

se5004l

The datasheet is very particular about this PA footprint since it generates a lot of heat. For that reason I've made the ThermalVia version the default and omitted that modifier from the name. I can't imagine any scenario in which you wouldn't use the thermal vias; the component would overheat and not work. I've made the connection to the copper pour in the bottom left slightly larger than specified in the datasheet, which calls for a width of 0.1mm. This would violate the minimum trace width requirements of many fab houses. I think the one I've used should be supported by most. Please let me know if any concerns/questions.

  1. I've violated the thermal via annular ring requirement since it is connected to the EP and satisfies the requirement anyway.
  2. I believe the mask errors are related to some of the pads overlapping the exposed pad, which is specified in the datasheet.

All contributions to the kicad library must follow the KiCad library convention

Thanks for creating a pull request to contribute to the KiCad libraries! To speed up integration of your PR, please check the following items:

  • Provide a URL to a datasheet for the footprint(s) you are contributing
  • An example screenshot image is very helpful
  • If there are matching symbol or 3D model pull requests, provide link(s) as appropriate
  • Check the output of the Travis automated check scripts - fix any errors as required
  • Give a reason behind any intentional library convention rule violation.

Be patient, we maintainers are volunteers with limited time and need to check your contribution against the datasheet. You can speed up the process by providing all the necessary information (see above). And you can speed up the process even more by providing a dimensioned drawing of your contribution. A tutorial on how to do that is found here: https://forum.kicad.info/t/how-to-check-footprint-correctness/9279 (This is optional!)
