1. A carrier boat for die package flux cleaning, comprising:
a body having at least one pair of substantially parallel sides, the body comprising one or more die package receptacles each oriented at a non-parallel angle relative to the substantially parallel sides of the body such that, when a die package is seated in a die package receptacle of the one or more die package receptacles, a first pair of opposing sides of a die of the die package are substantially perpendicular to the substantially parallel sides, wherein the body is configured to be directed in an X/Y plane via a conveyor belt through a flow of one or more stationary nozzles in a direction that is at a non-perpendicular angle relative to each side of each die package receptacle, wherein each of the one or more stationary nozzles is angled substantially perpendicular, in the X/Y plane, to the first pair of opposing sides of the die, and wherein each of the one or more stationary nozzles is angled toward the conveyor belt at a downward angle non-perpendicular to the conveyor belt.
