In an evident indication that Apple is exploring the 'waterproofing' feature for its new iPhone, a recently-filed patent by the company describes different waterproofing methods for the iPhone, iPad and MacBook.

The patent which Apple has recently filed with the United States Patent and Trademark Office is titled 'Methods for shielding electronic components from moisture.' The patent application chiefly describes how a device can be made water-proof by applying a protective 'hydrophobic' covering to its internal components.

According to AppleInsider, which first spotted the patent filing by Apple, the device-waterproofing mechanism detailed by Apple in its patent application primarily anticipated the damage that fluid can potentially cause to cellphones and other devices.

The waterproofing mechanism described by Apple in its patent application uses the 'chemical vapor deposition' technology. The waterproofing technique using the technology can help overlay water-sensitive components of cellphones; thereby protecting them against water damage.

Using the waterproofing technique detailed by Apple, a waterproof covering is applied to the cellphone's printed circuit board (PCB) as well as its electromagnetic interference (EMI) shield. The technique aims at making the whole device waterproof, rather than making it 'water resistant' to a certain extent.
