Helium fluorine oil pressure leak detection device is a set of automatic leak detection device, which is specially used for fine and rough inspection of semiconductor devices, integrated circuits, electronic products and other electronic components. It can be used together with helium mass spectrometer leak detector and heavy fluorine oil heater to carry out the whole process of fine and rough inspection of electronic components. Working principle 1. Helium pressure fine inspection of components. First, put the components in a pressurized sealed container. If there is leakage in the components, the helium will be pressed into the inner cavity. After taking out the components, put them into a vacuum container and use helium mass spectrometer leak detector to detect the leakage. 2. The components to be tested are put into the pressure vessel, and then injected with low boiling point fluorine oil to submerge the workpiece, and pressurize it for a certain period of time. After pressurization, take out the tested piece, and then immerse it in the heavy fluorine oil heated to 125 * C, and observe the bubbles. If bubbles are found, it can be judged as unqualified.

Application background

There is no clutch between the engine and gearbox of automatic transmission vehicle. The connection between them is realized by hydraulic torque converter. The hydraulic torque converter contains hydraulic oil. Once the hydraulic torque converter leaks, the transmission effect will be seriously affected. Therefore, the products should be tested for leakage before leaving the factory.
