  • Patent number: 12005481
    Abstract: An embodiment system, configured to clean a semiconductor package assembly, may include a sprayer device including a plurality of nozzles configured to direct a pressurized cleaning fluid toward the semiconductor package assembly; a conveyor configured to move the semiconductor package assembly relative to the sprayer device along a first direction; and a dryer spatially displaced from the sprayer device and configured to direct a pressurized gas flow toward the semiconductor package assembly to remove cleaning fluid introduced by the sprayer device. Each of the plurality of nozzles may be displaced from one another along a second direction to thereby generate respective separate spray distribution patterns. Adjacent nozzles may be further displaced from one another along a third direction to thereby a reduce an overlap of adjacent spray distribution patterns relative to a configuration in which the adjacent nozzles are not displaced from one another along the third direction.
