How are watches and smartphones made to be waterproof?
In: Technology
There are a variety of methods which can be used to make electronic components water resistant. Conformal coating of electronic components, airtight enclosures etc. The problem with mobile phones and water resistance is the need for consumer accessories which require external connections such as conventional headphones 3.5mm jacks and charging ports which can leak water into the mobile phone assembly. Hence the push by Apple and Google et al to move along mobile telephone assemblies to all BLE and contactless charging mechanisms.
