TPS61046: Is there a marker or indicator for pin A1 on the package---TPS61046YFFR?

Part Number: TPS61046

Dear Friend

I can't find an indicator of pin A1 for this BGA package (TPS61046YFFR), I am wondering if there is one.

If yes, maybe my magnifier is not good enough, if not, please let me know.

Thank you

Tony

Hi Tony,

There is a filled solid circle on the top side corner (not the ball side), which is the mark of pin A1.

Under the magnifier you may lift one chip side slightly. If the angle of view is good, it should be clear to see the mark.
