Ion-Mask Coating Could Make Waterproofing Electronics Easy

Engadget is reporting that a new chemical coating, originally designed to repel toxic vapors and liquids from soldiers' uniforms, may be the solution to small waterproof electronics. "The Ion-Mask is a special invisible coating that is chemically bonded to the device and repels water. It should allow waterproofing to make it into devices that are too small for the seals that are usually used to do the trick. Devices can have joins and gaps coated for a general level of water repellence, or have individual components treated for even more protection."

I don't know why this is a big deal for the Slashdot crowd. Might be nice for keeping the water out of my sneaks, but for electronics? Conformal coatings (like Humiseal) have been around forever... they're just expensive and make rework miserable.

Don't think this would work all that well on entire systems. Remember, most battery-module interfaces are connectorized. If you overcoat the connector, you will reduce surface contact between the connector sides, which increases electrical resistance. In other words, a little jiggle on the connector and your device resets itself.

If they don't waterproof the connector, no problem, but then you destroy the battery when the phone or ipod or whatever goes in the toilet. Which is better than losing the whole device, but most consumers won't know the difference. Or they use waterproof connectors which are bulky and expensive and don't belong in the middle of consumer equipment.
