Have anyone seen a QFN package like that? Why does it have a second row of pads between the die attach pad and the pins? Is the second row extensions of the outer row pins?

@NickAlexeev Best guess it that the QFN package is pad-limited, and those wires lead to a closer bonding location. The BGA package is half the size (like 4.5mm vs. 9.0mm), so it's possible that's the lead frame extending out more.

but I've never seen the leadframe extend through the bottom of the package that way before
looks like a nightmare for shorting pins together
