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 transferring the devices from the surface of the boat to the tray; characterized in that the method further comprises the steps of, interposing a grid, which comprises a plurality of cut-outs defined therein, between the surface of the boat and tray on which the devices are supported, so that the first stack further comprises the grid; arranging the grid so that, after the first stack has been flipped, the devices which are supported on the surface of the boat project into a respective cut out in the grid; after the first stack has been flipped, vibrating the grid and the boat so that each of the devices abuts an edge defining a respective cut-out, so as to move the devices into predefined respective positions on the surface of the boat. 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 transferring the devices from the surface of the boat to the tray; characterized in that the method further comprises the steps of, interposing a grid, which comprises a plurality of cut-outs defined therein, between the surface of the boat and tray on which the devices are supported, so that the first stack further comprises the grid; arranging the grid so that, after the first stack has been flipped, the devices which are supported on the surface of the boat project into a respective cut out in the grid; after the first stack has been flipped, vibrating the grid and the boat so that each of the devices abuts an edge defining a respective cut-out, so as to move the devices into predefined respective positions on the surface of the boat.
