There are a lot of components that make up finished hermetically sealed devices. These components could be placed into finished products such as an instrument, machine, rocket, analyzer, or person’s body. Due to the different harsh environments that these finished devices could possibly encounter, it is important for the engineers of these components to ensure that they are impenetrable – or rather hermetically sealed. To be hermetically sealed essentially means to be airtight so that nothing can come in or get out (i.e., gas, moisture, liquid, etc.). it is impervious to external influence. If the part isn’t hermetically sealed, damaged, or defective seals can allow an ingress of gas inside, which can result in an unwanted chemical reaction that can ultimately lead to product failure.
The finished devices that these components help build can be widely found in industries like aerospace and defense, implantable medical electronics, semiconductor, and automotive. Some examples of
