Mobile phones are essential electronic products for daily use, but the airtightness rate of mobile phones has always been a headache for mobile phone manufacturers. The reason is that its waterproof level must reach IP67/IP68 to ensure its waterproof performance.In order to ensure that the internal components of the mobile phone are not damaged when the mobile phone falls into the water or accidentally enters the water, it must go through the process during production.Air tightness testWhether it is qualified for this process.Mentioned mobile phoneAir tightness testing/Waterproof test, and we have to start with the waterproof structure of the mobile phone.In this article, Hai Ruisi will briefly introduce to you about mobile phones.Waterproof testthe importance of mobile phonesWaterproof testplans, mobile phonesWaterproof testtest methods.

Brief description of the structure of a mobile phone:

When mobile phones are produced, the waterproofing process involves all aspects (design, manufacturing, and testing), and the requirements are even more stringent.Air tightness testingThis process is more complicated and rigorous.All mobile phone manufacturers know that to ensure the waterproofness of mobile phones, each component must be tested for air tightness. The camera, headphone jack, speaker, SIM card, buttons, screen frame, back cover, etc. all need to be tested.Air tightness testing, including semi-finished mobile phones and finished mobile phones as a whole, need to be carried outAir tightness testing。

Shenzhen Hiraysi Automation Technology has been committed toMobile phone air tightness testingWe have extensive technical experience in the R&D and production of mobile phone devices, and have conducted a large number of mobile phone air tightness and waterproof level testing experiments.The most representative mobile phone test manufacturers that we have served include OPPO, Huawei, Apple, Foxconn, Xiaomi and other internationally renowned brands.

Mobile phone air tightness testBrief description of method:

Hai RuisiMobile phone air tightness testThe instrument uses imported sensors and a highly sensitive large-screen touch screen.The test accuracy reaches 0.1PA, and the integrated positive and negative pressure detection system is fully suitable for all difficulties in waterproof testing of mobile phones. The pressure test reaches -80 to 1000KPA, which is fully satisfactory for mobile phones.Air tightness testRequire.For those on mobile phonesAir tightness testThe principle is the pressure attenuation method. We will pressurize the finished or semi-finished mobile phone with gas to see the pressure change of the gas.To test the air tightness of a mobile phone we need to make a mold for the mobile phone.To test the air tightness of a mobile phone, many parts need to be sealed. Some parts can leak but water cannot pass through. We must seal these parts when making the mold.This is a major difficulty across the industry.However, Hirays has already overcome this problem and has now applied it to various components of mobile phones.Air tightness test。
