The story behind the waterproofing of mobile phones

According to what I’ve seen and heard, the most common mobile phone shock is “broken screen”. What is the most common internal injury? The answer should be “because of water in the phone”. Mobile phone water “Angry” I have a difficult situation because it is impossible to determine whether it can be recoverable as before and the damage is irreparable. Light input of water is not harmful, and serious input of water can cause “heart (electrical IC).” “Sudden stopping or even” brain (processor) “death.

Nowadays, more and more consumers’ mobile phones have been damaged by water, oil or other liquids. According to the data for the goods shipped for repair, liquid penetration is the second most common cause of broken screens, accounting for 35%. According to IDC survey data, in 2015 the liquid attack caused the loss of approximately 328 million smartphones worldwide, and the loss of liquid attack amounted to the US $ 96.7 billion.

    What is 96.7 billion? .7DP..7 billion is the equivalent of a country whose global GDP is higher than the ranking. It can be seen that the economic loss of mobile phones is extremely severe due to liquid intrusion. In addition, as smartphones become more powerful, they not only rapidly merge into consumers’ lives, but consumers also hope they can be used in more intense environments. In summary, it is especially important that the mobile phone has a waterproof function.

 According to the IDC report, less than 10% of smartphones worldwide are waterproof at this time. According to a report released by the Global Mobile Communication System Association (GSMA), global mobile phone use by 2017 The number of doers will exceed 5 billion. The mobile phones of such consumers are four and a half billion with no waterproof performance, and liquids can be exposed to liquids at any time to create “internal injuries”. So why doesn’t most smartphones have waterproof performance?

    The author believes that first, the cost of using waterproof technology for mobile phones will increase the cost, and the estimated cost will be $ 15-20. Some low-end smartphones cannot afford this cost. Secondly, the freedom of mobile phone design will be limited with the help of waterproofing. Given that many mobile phones with waterproof performance are a bit cumbersome, the last aspect is that the mobile phone uses a waterproof design, adding to this process will affect the production rate of the product if the order is large. So, productivity can be a problem.

Waterproof phone inventor

  Just like 18 years ago, Ericsson launched the world’s first waterproof mobile phone – the Ericsson R250 PRO, which uses magnesium metal body design with rubber treatment in spaces. Many details are specifically treated to ensure the waterproof performance of the key. It is noteworthy that the Ericsson R250 PR has become something of a waterproof mobile phone replica in the next few years.

What is the current waterproof phone?

    It is not difficult to understand that thick stereotyped mobile phones cannot get the “love” of consumers. In 2012,  Sony  Mobile incorporated the device-proof and waterproof function into the focus of mobile phone design, from the Xperia Acro S to the ultra-thin and light Xperia Z L36h, and then introduced a new breakthrough in the Xperia Z3 + waterproof technology. Is. Xperia Z3 + adapts Capless exposed waterproof technology to the USB interface, and the waterproof level reaches IP65 / IP68.

   In addition to Sony, another major mobile phone manufacturer has also started designing waterproof technology. Starting with the Galaxy S4 Active, Samsung has begun bringing water resistance to its flagship locations. Among them, the Samsung Galaxy S5’s IP protection rating is IP67, which means it can completely prevent foreign objects and dust from attacking, and submerges it in 1 meter of water. Ensure that the product is not damaged by immersion in 30 minutes. In the Samsung  Galaxy S7, the waterproof performance has been improved once again, reaching IP68 dustproof and waterproof. Apple’s  iPhone 7 supports  IP68 dust and water resistance.

So far, is the phone waterproof?

    Generally, a mobile phone is easily exposed to water: the difference between the template and the screen, the opening of the handset, the opening of the speaker, the USB data interface, and the difference between the physical keys and the template. In fact, there is no “black technology” to waterproof mobile phones. The common method used in early waterproof mobile phones was the sealant + rubber ring, and now the waterproofing of smartphones has been upgraded with sealant + rubber color + waterproof coating.

   To obtain a high level of waterproof technology (over IPX6) for mobile phones, it requires the cooperation of several processes. There are different sources of waterproofing in different parts. In some places, this process is different from the traditional concept of waterproofing. Should not use molecules of

    Generally, waterproof technology of smartphones uses different schemes in different parts. First, the shell is sealed with silicone rubber (paint, pad) and waterproof adhesive, sound waterproof (waterproof and breathable membrane), and more circuit boards are used. Other methods for achieving high levels of waterproof and nano-coating.

What to do with waterproof phones in the future?

    As mentioned above, the reasons for the lack of waterproofing in existing smartphones are high cost, restricting design and impacting productivity. So how will the smartphone perform waterproof performance in the future? Will waterproof performance become standard on smartphones?

    First, in regards to mobile phone waterproof technology, the author believes that the future will be the world of nanotechnology coatings. Nanocoatings can not only prevent the fluid from entering or dissolving, and can significantly reduce the contact between liquids and weak components inside and outside the mobile phone. Nano waterproof coating is sufficient to meet daily waterproofing requirements, and it is cheaper and more efficient and can improve product heat dissipation efficiency.

 For users who want waterproof performance of the device, nano-plating technology will be the best solution for cost-effectiveness. In addition, Samsung’s flagship phones and  the Apple iPhone 7  waterproof performance  of the  well  will appear waterproof smartphones in the future, however, however, it is clear that the current Nano plated Water-proof technology is still incomplete. Waterproof has not been reached. The waterproof effect of the technology (IPX6 above) needs to be further studied and strengthened. However, according to the current situation, in the next two years, the introduction of nano water-proof coating technology in “quality changes” is expected.

Many  mobile phone motherboards  currently  use nano-coated waterproof

  Motherboard Waterproofing is the last line of defense for mobile phones. Its main technical solution is to use polymer nanomaterial technology with lotus leaf effect. A polymer nanocomposite is a composite material that is less than 100 nanometers in dimensions of the dispersed phase. Nanomaterials have special properties such as surface effect, small size effect, optical effect, quantum size effect, macroscopic quantum size effect, etc., which can act as coatings. One type of nanomaterial has a lotus leaf effect (or lotus effect), which can obtain the usual super-hydro phobicity of lotus leaves. As a waterproof material, due to the effect of surface tension, The falling water will become water, the beads will not damage the internal contents of the electronic devices.

 The way to add a waterproof nano-coating to an electronic device is to place the electronic device in a vacuum environment and to inject a gaseous waterproof nanomaterial into a low-pressure state so that the gas surrounds the electronic device, and the device Plasma will be removed to facilitate the nanoparticles. By connecting, and then stabilizing, the surface of the electronic device, the surface of the electronic device’s components will consist of a layer of nanometres. After the design process, the thickness of the nano-coating on the entire electronic device is about one-thousandth of the diameter of the hair. At the same time, the surface is smooth and its surface is like lotus leaves.

Companies are currently doing nano-coating materials.

P2i Nano Waterproof Coating Technology  Company

    P2i was founded in 2004. Previously, it was a subsidiary of the British Defense Ministry’s Defense Science and Technology Laboratory. It was primarily committed to the development of various waterproof technologies. With the high quality and strong military background, P2I is a perfect example of the success of military technology transfer in military use. After the shift to the civilian market, P 2 The company is rapidly flashing in different fields. The signature of the brand ayrydyn basic as mobile phones,  MP3 players and electronic devices such as hearing aids are subjected to.  P2I coated the iPhone and iPod at the MWC 2012 conferenceSoaking in water caused a sensation in the venue, which made it famous in the mobile phone industry.

  P2I nano-waterproof technology refers to the coating of an only one-nanometer thick polymer layer on the entire surface of the product. This layer of film can be attached to the surface of the product in a molecular form and is integral. ۔ This process can reduce the surface energy to a very low level, which is a third of PTFE (polytetrafluoroethylene). After contact with the coating, it will penetrate the liquid water droplets and maintain the appearance of the material. Will remain Therefore, it has excellent resistance to oil and water.

HzO Waterproof Technology Enterprise

HzO is a Utah-based high-tech company with water block technology for consumer and industrial electronic components. Waterblock technology is the trademark of the HzO-level therapeutic trademark. This technology can create nano-scale curing on the surface of electronic components, thus preventing electronic components from being damp, sweaty and moisture. And save on mobile phones, media players, notebooks and more. Protects the molecular surface of corrosion from water and other liquids. HzO’s nano-film technology can achieve IPX7 or IP67 waterproof standards for electronic products and can protect at least 30 minutes in one meter of water.

Liquiple water proof technology

   LeCaple is a hi-tech company in California. At CES 2012, LeCapel demonstrated its nanotechnological coating technology. Using this technology can send a mobile phone to the water without damaging the mobile phone. The LeakyPal waterproof solution is to spray nanoparticles in the form of gas on the surface of electronic devices under vacuum environments to create a “water proof output” to detect products that have three proofs to enhance the waterproof function. Capacity is not available. According to the company’s director, a new generation of water proof technology can reach the level of IPX7, which means that equipment using this technology can be used for 30 minutes in one meter of water. Can stay

    The method of liquid coating is to place the body in a vessel, and then create a low-pressure environment near the vacuum so that the injected liquid can convert the waterproof material into a gas state. At the same time, the fans inside the machine There are cedar flaps to allow gas to be covered. At each corner of the device (as long as there is little space to enter the body), the gas is cooled and then it is waterproof coating.
