One of the things iPhone owners should be worried about is water damage. However, if a patent application sees the light of day, iPhone owners may never have to worry about water damage ever again. Apple has filed a patent application, suggesting that the next iPhone may be waterproof. The patent application with the USPTO was spotted by AppleInsider.
METHODS FOR SHIELDING ELECTRONIC COMPONENTS FROM MOISTURE
Methods for applying a hydrophobic coating to various components within a computing device are disclosed. More specifically, a hydrophobic coating can be applied by a plasma assisted chemical vapor deposition (PACVD) process to a fully assembled circuit board. Frequently, a fully assembled circuit board can have various components such as electromagnetic interference (EMI) shields which cover water sensitive electronics. A method is disclosed for perforating portions of the EMI shields that overlay the water sensitive electronics. Methods of sealing board to board connectors are also disclosed. In one embodiment solder leads of the board to board connectors can be covered by a silicone seal.
A method for enhancing moisture resistance of an electronic component mounted on a printed circuit board (PCB) and within an electromagnetic interference (EMI) shield having a plurality of openings, comprising: depositing a hydrophobic conformal coating on an exterior surface of the EMI shield, wherein at least some of the hydrophobic conformal coating passes through at least some of the plurality of openings and forms a moisture resistant coating on the electrical component.
Note that not all patents see the light of day. But if this patent does, it suggests that the iPhone 6S and the iPhone 6S Plus will be waterproof.
