Texas_DSBGA-10_1.36x1.86mm_Layout3x4_P0.5mm and Texas_DSBGA-12_1.36x1.86mm_Layout3x4_P0.5mm have no correct size reference and violate KLC F5.1(3)
The document specified as reference for these 0.5mm pitch DSBGAs ( http://www.ti.com/lit/an/snva009ag/snva009ag.pdf ) does not actually specify a footprint for DSBGAs of this pitch. The document only specifies footprint recommendations for BGAs with 0.4mm pitch, and for 0.5mm BGAs of a particular type (picostar) which these are not. The datasheets for the parts using these footprints have correct size references.
These two parts have the orientation mark on pad A3, not A1. The footprints don't indicate this.
In addition, these two fps have the silkscreen less than 0.1mm from exposed copper. KLC specifies 0.2mm from exposed copper.
