THE INSPECTION MACHINE HAS A CONVEYER FOR CARRYING A SOLAR WAFER, AN OPTICAL INSPECTION SYSTEM FOR INSPECTING THE SURFACE AND COLOR APPEARANCE OF THE WAFER AND AN ILLUMINATION INSPECTION SYSTEM. A HOLDER IS PROVIDED IN THE INSPECTION POSITION WHERE THE WAFER IS CLAMPED ALONG ITS WIDTH DIRECTION TO PREVENT THE WAFER FROM OFFSET. DURING THE OPTO-ELECTRICAL INSPECTION, PROBES ARE BROUGHT INTO CONTACT WITH CONDUCTIVE BUSES OF THE WAFER AND LIGHT IS APPLIED TO THE WAFER TO ALLOW THE PROBING OF ELECTRIC ENERGY THUS GENERATED. AN ADJUSTING DEVICE IS EMPLOYED TO ADJUST THE CLAMPING GAP OF THE HOLDER AND THE DISTANCE OF THE PROBES IN ACCORDANCE WITH THE SIZE OF THE SOLAR WAFER. THE DATA ARE COLLECTED AND TRANSMITTED TO A SORTING SYSTEM FOR SORTING THE WAFER.

Abstract: A system and a method for calibration of optical measurement devices are described. In one embodiment, the optical measurement device comprises an imaging lens, and the calibration system includes a projection light source, a lens module, and a projection element. The light emitted from the projection light source passes through the projection element and is projected by the lens module, and then captured by the imaging lens of the optical measurement device. The exit pupil of the lens module in the calibration system is coincident with the entrance pupil of the imaging lens of the optical measurement device, providing a compact and highly efficient optical calibration mechanism.

Abstract: A heat exchange device and a cooling system are provided. The heat exchange device includes a low-pressure chamber and a high-pressure chamber disposed in the low-pressure chamber. The low-pressure chamber has a first wall for enabling heat exchange and an output portion in communication with the outside to output the low-pressure fluid. The high-pressure chamber has an input portion in communication with the outside to admit the high-pressure fluid and nozzles in communication with the low-pressure chamber. The fluid discharged from the nozzles undergoes a pressure drop and undergoes heat exchange through the first wall. Cooling capability is developed in the heat exchange device and works in the heat exchange device to thereby dispense with a pipeline which must be otherwise provided to link an expansion process and an evaporation process of the fluid and may otherwise cause cooling capability loss, so as to greatly enhance heat exchange capability and cooling efficiency.

Abstract: An inlet module is adapted to be disposed on a housing of an electronic device, and includes an insert board and at least one adjusting plate. The insert board has a plurality of first air passages, at least one second air passage, and at least one positioning unit. The second air passage is located between two of the first air passages, and has an area larger than that of each first air passage. The adjusting plate has an opening having an area smaller than that of the second air passage. The adjusting plate is operable to be positioned at a position where the opening and the second air passage are overlapped with each other, thereby reducing an area of the airflow passing through the second air passage.

Abstract: A source measure device includes a current sampling circuit, a voltage sampling circuit, an overvoltage detecting circuit, and a comparing circuit. The current sampling circuit is configured to sample a current of a device under test. The voltage sampling circuit is configured to sample a voltage of the device under test. The overvoltage detecting circuit is coupled to the current sampling circuit and the voltage sampling circuit, and receives a first operation voltage of the current sampling circuit and a second operation voltage of the voltage sampling circuit so as to generate a detection voltage. The comparing circuit is coupled to the overvoltage detecting circuit, and determines whether the detection voltage is within a voltage range. If the detection voltage is not within the voltage range, the comparing circuit generates an abnormal signal.
