Nowadays, to make smartphones waterproof, companies close the gaps between the frame and back panel, use silicone gaskets and rubber rings on ports and buttons, and apply nano-hydrophobic coating on the motherboard. These measures keep the phone safe from water and moisture, so that users can use the phone even in rain or swimming pool.
Waterproof Smartphone Technology: Nowadays smartphone companies adopt many techniques to make their devices waterproof. Silicone gasket, rubber ring and hydrophobic membrane are used to protect the phone’s body, charging port, SIM tray and buttons. Additionally, nano-hydrophobic coating is applied on the motherboard and connectors. These safety measures protect the phone from water, moisture and accidental liquid exposure, allowing users to use the phone even in the rain or swimming pool, without the fear of the device getting damaged.
Security starts from the body of the phone
Nowadays many smartphones can work even in water for some time. The waterproofing technology of the companies works behind this. While making the phone, any gap between the frame and the back panel is completely closed. This reduces the possibility of water getting inside. Special attention is paid to every small hole and slot so that the internal circuitry of the device remains safe.
Special sealing and port protection
Silicone gaskets and rubber rings are used on parts like charging port, SIM tray and buttons. For example, the waterproof ring installed in the SIM tray gets compressed as soon as it goes inside and prevents water from reaching the internal parts. Hydrophobic acoustic membrane or special mesh material is used for the speaker, which allows sound waves to pass while blocking water.
Boost protection from nano-hydrophobic coating
Despite this, if some moisture or water enters the phone, then nano-hydrophobic coating is done on the motherboard and connector. This coating helps repel water from the surface and gives additional protection to the device. However, this is not full-proof protection and is considered as a backup protection only.
