As hand-held electronic devices and military communications become more sophisticated, the internal electronic enclosures must be protected against water, soap, dust and dirt. Electronics generate heat during use, increasing internal temperatures, and building pressure inside the enclosure. When temperatures abruptly drop, a vacuum of more than 200 mbar (3 PSI). Over time, these rapid variations in pressure and resulting vacuums cause seals to develop gaps that allow contaminants to enter and damage the electronics.
