I believe everyone is very aware of the importance of waterproofing mobile phones.Now the mobile phone is one before leaving the factoryWaterproof testing, is an indispensable and necessary link for all manufacturers.The air-tightness test of mobile phone waterproofing is a standard to ensure that the waterproof performance of mobile phones can meet the standards. As the first barrier to waterproofing, the mobile phone shell is important and cannot be ignored!What I want to share with you this time isAir tightness detection of mobile phone back shellcase.

As you can see from the picture above, we put the mobile phone case into a customized mold and then inflated it with compressed air to conduct an air tightness test. Then we used the instrument's high-precision sensor to detect changes in air pressure, and judged whether the waterproof performance of the mobile phone case was qualified based on the leakage value.
