Method and apparatus for a submersible electronic device

A submersible electronic device, comprising:

• a leak-proof device body defining an internal chamber therein, wherein the internal chamber includes means for conveying power and data to and from the device;
• a resealable fluid access port disposed on the body of the device, the port being in fluid communication with the internal chamber;
• a user interface disposed on the device body;
• a sealing gasket being disposed between the fluid access port and the user interface;
• electronic components disposed within the device body;
• and
• wherein the device body is completely filled with a liquid having the characteristics of being compatible with sensitive materials found in electronic devices, so that the liquid filled body and device are capable of withstanding extreme environmental pressures.

A method of making a submersible electronic device the submersible electronic device having a fluid access port disposed on the device body, comprising the steps of:

• providing a vacuum chamber work space;
• and then,
• opening the fluid access port on the device;
• and then,
• placing the device inside the vacuum chamber work space;
• and then,
• evacuating air from the vacuum chamber work space;
• and then,
• injecting a fluid selected from the group consisting of a perfluorocarbon liquid, a hydrofluorether liquid, a perfluoropolyether liquid, and a liquid mixture of alkylene glycol, de-ionized water, and a corrosion inhibitor into the vacuum chamber work space to provide total immersion of the device therein;
• and then,
• allowing the fluid to enter the device through the fluid access port;
• and then,
• sealing the fluid inside the body of the device;
• and then,
• removing the fluid filled device from the vacuum chamber.
