Interpretation of the Story Behind the History of Mobile Phone Waterproofing

发布者:管理员   日期:2019-10-15

Nowadays, more and more consumers' mobile phones are damaged by water, oil or other liquids. According to the statistical repair equipment, liquid intrusion is the second biggest cause of damage after the broken screen, accounting for up to 35%. According to IDC survey data, in 2015, about 328 million smartphones worldwide were damaged by liquid intrusion, and the loss of the city due to liquid intrusion was as high as 96.7 billion US dollars.

What is the concept of $96.7 billion? The US$96.7 billion is equivalent to a country with more than 60 global GDP rankings. It can be seen that the economic loss caused by liquid intrusion is extremely heavy. In addition, as smartphones become more powerful, they are not only increasingly integrated into the lives of consumers, but consumers also want them to be used in more harsh environments. In summary, it is especially important that the phone has a waterproof function.

The mobile phone's water inlet board is corroded and there is "internal injury"

According to the IDC report, less than 10% of smartphones worldwide are waterproof. According to the Global Action Association (GSMA) report, by the middle of 2017, the number of mobile phone users worldwide will exceed 5 billion; this means 45 The mobile phone of 100 million users does not have waterproof performance, and may be subjected to "injury" due to liquid intrusion at any time. So why are most smartphones not waterproof?

The author believes that the first mobile phone support waterproof technology will increase the cost, the estimated cost should reach 15-20 US dollars, some low-end smart phones can not afford this cost; secondly, support the waterproof will also limit the degree of freedom, which is what we see Many mobile phones with waterproof performance are slightly cumbersome; on the other hand, the mobile phone adopts waterproof design, and the increase of the process will affect the production yield of the product; if the order quantity is large, the production capacity may have problems.

What is the current waterproof phone?

It is not difficult to understand that the thick and rigid three-proof mobile phone is not able to get the "love" of consumers. In 2012, Sony Mobile put the dustproof and waterproof function into the focus of mobile phone design, starting from Xperia Acro S, to the ultimate thin and light The Xperia Z L36h, and then the Xperia Z3+ brings new breakthroughs in waterproof technology. The Xperia Z3+ uses Capless uncovered bare waterproof technology on the USB interface, and the waterproof level reaches IP65/IP68.

First of all, in the waterproof technology of mobile phones, the author believes that the future will be the world of nano-waterproof coating. Nano-plating not only prevents liquid from entering or eroding, but also greatly reduces the contact between liquid and internal and external parts of the mobile phone; and compared with mechanical physical seals. Nano-waterproof coatings are sufficient for everyday waterproofing, at a lower price and more efficient, and also improve the thermal performance of the product.

Nano-plating technology will be a cost-effective solution for users who want waterproof equipment. In addition, with the waterproof performance of Samsung's flagship mobile phone and Apple iPhone 7, there will be more smartphones supporting waterproof in the future; however, it should be noted that the current nano-coating waterproof technology is still not perfect and does not reach waterproof. The waterproof effect of technology (IPX6 and above) remains to be further studied and strengthened. However, according to the current situation, nano-waterproof coating technology is expected to usher in "quality change" in the next two years.

Nano-waterproof technology refers to the application of a layer of polymer on the entire surface of the product in nanometers. This film can be attached to the surface of the product in molecular form and is inseparable. This process reduces surface energy to an extremely low level - as low as one-third of PTFE (polytetrafluoroethylene). Once in contact with the coating, the liquid condenses into water droplets and the material remains unchanged. Therefore, it has good oil and water resistance.
