Add Texas_DSBGA-20_1.56x1.96_Layout4x5_P0.4mm
Created by: potatopplking
Added Texas Instruments DSBGA-20 footprint (used by e.g. SD/MMC voltage-translation transceiver TXS0206)
Link to TXS0206 datasheet, footprint drawing on pages 30-33
Check script check_kicad_mod.py reports 2 warnings
Checking footprint 'Texas_DSBGA-20_1.56x1.96_Layout4x5_P0.4mm':
Violating F6.3
Pad requirements for SMD footprints
Pad(s) potentially missing layers
- Pad 'A1' missing layer 'Paste'
- Pad 'A2' missing layer 'Paste'
...
- Pad 'E4' missing layer 'Paste'
Violating F9.2
Footprint properties should be left to default values.
Attribute solder_mask_margin == 0.05 != 0!
- Violating F6.3: paste and copper pad have different shapes (as recommended in datasheet), therefore are supplied in different pins
- Violating F9.2: all copper pads are the same, therefore using footprint property for setting solder mask margin makes sense
Also this is my first contribution, hopefully everything is ok :)
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!)
