How to check waterproof test and air tightness test for mobile phones

The methods of waterproof testing and air tightness testing of mobile phones mainly include water testing method and pressure attenuation methodHuber&Ranner non-standard air tightness test equipment can inflate, stabilize and test mobile phones in a short time, so as to accurately measure the leakage rate of air. Based on the upper limit of the leakage rate, you can accurately determine whether the waterproof level of the mobile phone meets the standard. This efficient and accurate detection method greatly improves the waterproof pass rate of mobile phone production.
