A method for testing dies using a machine grooved storage tray with vacuum channels. The method involves drawing a vacuum upon the dies while held in the storage tray and using an automated vision system to map the location of dies in the pockets of the storage tray. Using the map, the storage tray is maneuvered for 5 each individual die in relation to a test probe in order that contact and testing may be made between the discrete die and the test probe.
