The relative cost is also high. For mass-produced electronic products, the long delivery period will affect the time of listing. 2. If there is leakage in the pressure chamber itself and the seal, the pressure will also drop. Therefore, it is impossible to judge whether the electronic device or the sealed chamber is leaking, which will affect the detection result and its accuracy will be lowered.

Moreover, a fixture (not shown) is disposed in the container 20 for fixing the electronic device 10. The fixture is not the focus of the present invention and will not be further described herein.

In this embodiment, the compressed gas supply device 30 mainly supplies the compressed gas required by the detecting device, and the compressed gas supply device 30 is coupled to the air supply side of the outer casing 11 of the electronic device 10 in the sealed container 20, and the present embodiment For example, the outer side 14 of the electronic device casing 11 is provided, and the inner side 13 of the electronic device casing 11 is provided as the inspection side, since the gas supply side is filled with the compressed gas, and the inspection side is the general atmospheric pressure, therefore, the gas supply is performed. The side pressure is greater than the pressure on the side to be inspected. Example Further, a pipe 73 is connected to the gas supply side of the compressed gas supply device 30 and the electronic device casing 11 in the hermetic container 20, that is, the outer side 14 of the electronic device casing 11.

After the high-pressure gas expands, the flowmeter 40 is actuated through the flowmeter 40 through the pipeline 71, and the leakage of the electronic device casing 11 can be judged. If the electronic device casing 11 does not leak, the high-pressure gas does not enter the inspection side, so that no gas is output to the flowmeter 40 on the inspection side, and therefore, the flowmeter 40 does not operate. The advantage of this embodiment is that when the sealed container 20 also leaks (refer to the arrow L1 in FIG. 1), if the electronic device casing 11 has a leak (L2), the flow meter 40 operates, and when the electronic device casing 11 does not leak, the flow meter 40 does not act, therefore, the leakage of the closed container 20 does not affect the detection result of the flow meter 40, and can solve the problem in the prior art that when the pressure gauge is used for detection, if the sealed container 20 also leaks, the detection result will be affected. The problem, and the flow meter is very sensitive, can complete a test in 2~5 seconds, compared with the traditional pressure detection takes about 30 seconds, convenient and fast.

The input/output module 45 can adopt a touch screen as an operation panel, and can be used as an input command and an output graphic message. The flow analog signal obtained by the flow meter 40 is converted into a digital signal, processed by the operation module 42 and displayed by the output module 45. The accuracy is very high, and a small leak can be detected and displayed.
