Sealed Sensor Assembly Gets A Reliability Boost

Traditionally hermetically sealed wire feedthroughs are the best way to incorporate sensors and sensing electronics into a pressure or vacuum chamber. However, there is another lesser-known way: you can instead hermetically seal circuit board assemblies that interface with a sensor. In the right applications, sealed circuit board assemblies have some persuasive performance and cost benefits.
