Making an Airtight Case for Hermetically Sealed Packaging
A hermetic seal is any type of sealing that makes a given object or package airtight, preventing the passage of air, oxygen or other gases. Hermetically sealed packaging is essential to the correct and safe functionality of many electronics, especially for high reliability applications such as aerospace, downhole drilling and industrial.
Common requirements for high reliability
- Metal or ceramic materials
- Hybrid products
- Internal ceramic substrates (electrically isolated & thermally conductive)
- Wide temperature range (low as -55˚C & high as 200˚C)
- Nitrogen interior with 0% moisture
5 types of high reliability packages
- TO-3
- PowerDIP
- Ceramic DIP
- PowerSIP
- PowerQuad
Main applications
- Aerospace
- Downhole drilling
- Motor drives
- Heavy robotics
