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 . <EOS>
