Why Vent? Improve reliability for rugged electronics

Customers use electronics anytime and anywhere, so these products need to be able to withstand any situation. Yet designing a device to be used in harsh environments presents many unique challenges. The device must be sealed to protect its sensitive electronics against water, dirt, dust, and other contaminants. To create effective seals, many designers choose to increase wall width or use stronger o-rings; however, these solutions do not address the underlying issue – pressure variations caused by the environment. This presentation investigates the causes of product failure and how venting alleviates many of these issues.
