Abstract

According to the present invention there is provided a method of handling devices comprising the steps of, receiving a tray on which devices to be tested are supported, into a flipping station; positioning the tray under a boat, so that the devices which are supported on the tray are sandwiched between the tray and a surface of the boat which can support devices, to form a first stack; flipping the first stack, so that the tray is positioned over the boat, to cause the devices to fall, under the influence of gravity, away from the tray to become supported on the surface of the boat, thereby transferring the devices from the tray to the surface of the boat; moving the boat to a testing station and testing the devices on the boat; receiving the boat of tested devices into the flipping station; positioning a tray over the boat, so that the devices which are supported on the surface of the boat are sandwiched between the surface of the boat and tray to form a second stack; flipping the second stack so that the boat is positioned over the tray, to cause the devices to fall, under the influence of gravity, away from the surface of the boat to become supported on the tray, thereby transfe…
