Abstract
A method and system are provided for flipping a tray of parts such as integrated circuit packages including a pair of flippable storage trays. A first storage tray has an upper surface which forms a grid of storage compartments wherein each of the storage compartments is adapted to hold a single integrated circuit package. Initially, the first tray is received at a flip station from a first part processing station. Then, the first and second trays are joined together so that they mate. Then, the mated first and second trays are inverted so that the packages are held in the second tray. Then, the first and second trays are separated and the second tray which now holds the plurality of packages is transferred to a second part processing station. Then, the cycle is repeated with a third tray of parts and the now empty first tray.
