1. An automated method of cleaning trays used in handling circuit device packages, comprising:
placing a plurality of trays on a tray loading station of an automated tray cleaning machine;
vertically lowering in an automated manner a first tray of the plurality of trays onto a pair of spaced apart conveyor belts while supported on a first support plate that moves vertically relative to the pair while a remainder of the plurality of trays are maintained vertically spaced above the first tray, the first support plate being lowered between the pair to allow the first tray to contact the pair;
conveying in an automated manner the first tray from the tray loading station into a cleaning chamber with the pair;
automatically applying pressurized air in the cleaning chamber to one or more surfaces of the first tray to remove debris from the first tray;
conveying in an automated manner the first tray out of the cleaning chamber and to a tray unloading station with the pair; and
raising in an automated manner the first tray above the pair with a second support plate of the tray unloading station that moves vertically relative to the pair while the second support plate is disposed between the pair and vertically positioned relative to the pair to allow the first tray to be conveyed over the second support plate, which vertically raises the first tray off the pair.
