The QFN-12 part designated U4 corresponds with a RF switch that includes a ground pad. To accommodate this footprint the project publishes a custom module.
Steps to reproduce
Refer to the layout design
Examine the ground pad of U4
Refer to the X.274 archive paste layer
Compare the U4 lithography shape
Expected result
Both layout and manufacturing files indicate a ground pad in the U4 paste layer.
Actual result
The U4 module is flawed and only indicates a ground pad in the layout.
Workaround
Ask the steel foil fabrication service to manually open the U4 ground pad aperture.
Severity level
This is medium priority because the U4 RF switch is of high importance for proper runtime to correctly specify.
