Nowadays, many mobile phones focus too much on appearance and ignore practical three-proof functions.。A three-proof mobile phone is a mobile phone with slight dustproof, shockproof and waterproof functions.，Therefore, it has always been loved by young users who love outdoor sports.

Three-proof mobile phone back case waterproof detectionMold

For rugged mobile phones on the market, the side waterproof structure usually uses screws to fix the upper and lower shells, and the upper and lower shells directly interact to compress the waterproof rings to achieve waterproofing effect. However, the waterproof consistency of this structure is not perfect, and the assembly process is cumbersome and needs to be improved.Rugged mobile phones often use the internal sealing technology of the mobile phone motherboard, so that each component is covered with white glue orblackThe glue is encapsulated to have an insulating effect, which also achieves the purpose of waterproofing.

Product to be tested: Rugged mobile phone back case

Current waterproof testing technology generally tests the back shell of a three-proof mobile phone. This time, the customer needs to test the back shell of a three-proof mobile phone.IP67For the waterproof level test, Hirays Technology used the following equipment and solutions:

Equipment used: HiraysHPPioneer seriesAir tightness and waterproof detector

Solution: Use direct testing method to test, design a copy mold according to the structure of the mobile phone back case, use the mold to seal the opening of the mobile phone back case and the camera part, test parameters: test pressure17KPA, inflation time10S, stabilization time10S, test time5S, upper limit of leakage value0.02KPA, put the back case of the mobile phone into the mold and press the start button on the instrument or tooling. The mold presses down to seal the back case of the mobile phone. The instrument inflates, stabilizes and tests the back case of the mobile phone. It detects its leakage by monitoring the air pressure changes inside the back case of the mobile phone, and automatically determines products that exceed the upper limit of leakage or fail to reach the test pressure.NG, the qualified products are judged asOK。
