The pass rate of mobile phone waterproof testing has always been a headache for mobile phone manufacturers, so mobile phoneWaterproof testing equipmenthas attracted widespread attention. In this context, a new generation of air tightness detector has been produced, dedicated to mobile phones.Waterproof testingAir tightness testing equipment.

When it comes to mobile phone waterproof testing, we have to start with the waterproof structure of the mobile phone.

The maturity of the new generation of waterproof technology allows mobile phones to add waterproof functions without being as bulky as three-proof phones. Flagship mobile phones represented by Sony series mobile phones and Samsung flagship S7/NOTE7 have maturely applied the highest level of IP68 waterproof function. Apple's latest iPhone 7 also supports IP67 waterproof, and watches support IP6850m waterproof, Apple has always been a technological benchmark, and is expected to lead the follow-up of domestic brands next year, fully extending watches to wearable and other 3C products, and also making great achievements in many fields such as automobiles and medical care.It is expected that domestic brands will fully participate in waterproof innovation next year, and the tens of billions of market explosion is imminent.To ensure the pass rate of mobile phone waterproof testing, air tightness testing equipment can be used.

  Compared with industrial applications, the requirements for all aspects of the waterproof process of mobile phones (design, manufacturing, and testing) are more stringent and demanding. Air tightness testing,Waterproof testing equipmentMore complex.From the overall situation, to achieve high-level waterproofing technology (IPX6 or above) requires the cooperation of a variety of processes, and the waterproofing methods are diverse for different parts.Some local processes are quite different from the traditional concept of waterproofing. For example, in the microphone and earpiece parts, due to the need to conduct sound, special processes must be used that can only allow air molecules to pass through, but not water molecules.Generally speaking, the waterproof technology of smartphones adopts different isolation solutions for different parts. First, the outer casing is sealed with silicone rubber (rings, pads) and waterproof adhesive, acoustic waterproofing (waterproof and breathable membrane), and further uses various methods such as circuit board waterproofing (nano material coating) to achieve high-level waterproofing and air-tightness effects, thereby achieving a higher level of waterproofing detection level.

The combination of so many waterproofing technologies will definitely lead to various non-waterproofing problems. How to solve the difficulties in this aspect has become an important research topic in the mobile phone industry.Shenzhen Hiraysi Automation Technology has been committed to the research and development of air tightness detectors for ten years.Recently, I am more interested in mobile phones.Waterproof testing equipment, conducted a special study on air tightness detection technology.And we have done a lot of mobile phone air tightness and waterproof level testing experiments.

After a lot of experiments and practice, mobile phone air tightness detection technology research and summary.A non-destructive compressed air air tightness tester specially used for mobile phone waterproof testing equipment and air tightness testing has been developed.

This waterproof testing equipment is equipped with a barcode scanner and a remote formulation system.

The waterproof detection equipment uses imported pressure sensors and highly sensitive large-screen touch screens.The test accuracy can reach 0.1pa, and the positive and negative pressure air tightness detection system is integrated, which can be fully applied to all aspects of mobile phone waterproof detection difficulties.The pressure test range is -80 to 1000Kpa.

Waterproof testing methods for waterproof testing equipment:

1. Connect the power supply and air source of the waterproof testing equipment, and connect the test port to the mobile phone waterproof testing tooling. The tooling needs to be made according to the size of the mobile phone.

2. Start the mobile phone air tightness tester with both hands, and then the air tightness test goes through the process of inflating, stabilizing, and testing, and then the air leakage rate is obtained.

three,Waterproof detectorThe waterproof level of the mobile phone can be determined based on the leakage upper limit of the device. If it is less than the leakage upper limit, it is qualified, and if the size is less than the leakage upper limit, it is unqualified.The whole test process only takes more than 10 seconds
