The working principle of mobile phone air tightness testing equipment

With the advancement of science and technology, the performance of mobile phones has been gradually improving. Mobile phones have become an essential item for people when going out every day, and as a result, competition among them has become increasingly fierce.

Therefore, solving phone leakage is one of the headaches for phone suppliers. In fact, if you want to solve this problem, you need to use phone air tightness testing equipment. It features a high-precision pressure sensor, so people do not need to inspect it with the naked eye. Of course, our eyes cannot see phone leakage. Phone leakage is the result of data calculation.

The working principle of the mobile phone air tightness testing equipment: The interior of the mobile phone or the inner cavity of the simulated mold is inflated through a pressure valve. The air pressure value should be specified based on the volume of the internal space of the product and the inner cavity space of the simulated mold.

When the mobile phone air tightness testing equipment reaches the standard value, the gas source is cut off to ensure that the constant air pressure inside the product or the simulated mold cavity remains stable for a period of time.

Once the air pressure has stabilized, the test phase begins. The pressure sensor of the phone air tightness tester records the current pressure value in real time. After a period of testing, the real-time pressure value of the product cavity or the model cavity is recorded according to the standard phone test time.

By analyzing and calculating the leak detection system of the mobile phone air tightness tester, the differential pressure between the two pressure values is compared to determine whether the mobile phone has a leak.
