Trigger crossbar front panel board is back from fab.
It looks like I mostly pulled off the 0.5mm pitch BGA, but the Vbat via looks to be insufficiently tented so I might get it failing open there. Should have moved the via slightly further away from the ball to reduce the risk of such a failure.
Good news is, I don't think this will matter for two reasons.
The actual Vbat ball is not the one next to the via, it's the one to the right. The outer-ring ball is an unused GPIO that I'm just using as a route-through. The same is true of the via in the northeast corner of the array where the annular ring is eating into the BGA land.
In both cases the outer-ring ball is a route-through and so some wicking resulting in the BGA failing open at that pin won't matter whatsoever.
I'm not using the backup-memory feature anyway, and when Vdd is supplied the MCU runs off that instead.
