What Are Hermetic Feedthroughs?
Hermetic feedthroughs are specialized components that allow electrical current or signals to pass through an airtight barrier while maintaining a perfect seal. They are essential in industries like aerospace, defense, medical, and semiconductor manufacturing, where even microscopic leaks can compromise safety and performance. Designed with absolute precision, these feedthroughs maintain the stability of electrical systems under high vacuum, pressure, and temperature variations.
How Hermetic Feedthroughs Work
A hermetic feedthrough uses glass-to-metal or ceramic-to-metal sealing to create a molecular bond between conductive pins and their housing. This ensures gas-tight performance while electrically isolating the conductive elements. The result is stable electrical transmission in environments where ordinary connectors would fail due to temperature or atmospheric stress.
Custom Feedthrough Design
Complete Hermetics designs and manufactures custom hermetic feedthroughs for single-pin, multi-pin, RF, and high-voltage configurations. Each product is precisely engineered to meet customer-specific requirements for dielectric strength, mechanical endurance, and leak-rate performance. Every feedthrough undergoes helium leak testing (as low as 1 × 10⁻⁸ cc He/sec) to ensure consistent quality and compliance with industry standards.
Materials for Maximum Reliability
Using advanced materials such as stainless steel, Kovar, titanium, and high-grade ceramics, Complete Hermetics ensures excellent thermal stability, corrosion resistance, and electrical performance. Optional plating in gold, silver, or nickel further enhances conductivity and long-term reliability. These materials perform consistently across wide temperature and pressure ranges, making them ideal for mission-critical applications.
