Duno. Which LPI Solder Mask are you using?

Did you get the solder to the temperature? Determine the temperature of the solder with a thermocouple.

We have hand mixed several million grams of solder paste in the last 20 years. No problems to date.

Try: ANSI/J-STD-002, Solderability Tests for Component Leads, Terminations, Lugs, Terminals, and Wires

Sounds like solder is not taking to the pads of the BGA interposer. Check the solderability of the component.
