Ultra-High Vacuum Feedthrough Solutions

Posted by admin on

 

High vacuum feedthroughs are designed for applications requiring ultra-low leak rates and stable performance under vacuum conditions. These components allow electrical current to pass through sealed chambers without compromising pressure integrity.

 

Vacuum Integrity and Leak Protection

In high-vacuum systems, even minute leaks can contaminate processes or reduce equipment efficiency. High vacuum feedthroughs are tested using helium mass spectrometry to ensure airtight sealing performance.

 

Sealing Technologies

Complete Hermetics produces glass-to-metal feedthroughs and ceramic-to-metal feedthroughs optimized for vacuum compatibility. Glass seals provide cost-effective solutions for moderate conditions, while ceramic seals support higher temperatures and voltages.

 

Optimized for Ultra-Low Leak Rates

Ultra-high vacuum systems require feedthroughs capable of maintaining exceptionally low leak rates. Precision sealing and material selection are critical to minimizing outgassing and ensuring vacuum consistency. High vacuum feedthroughs manufactured by Complete Hermetics are engineered with compatible metals and sealing materials to withstand thermal expansion and mechanical stress. This ensures consistent pressure stability in research, semiconductor, and aerospace systems.

 

Custom Configurations

Feedthroughs may include multi-pin layouts, bulkhead mounting, and laser-welded installations. Materials such as stainless steel, titanium, and Kovar ensure mechanical durability and corrosion resistance.

 

Applications

High vacuum feedthroughs are essential in semiconductor fabrication equipment, aerospace simulation chambers, laboratory research systems, and medical imaging technology.
