Critical Role of Vacuum Feedthroughs in HighVacuum Systems
Ensuring Integrity in High-Pressure Environments
by Douglas Electrical Components
Introduction to HighVacuum Systems
1 Defining High-Vacuum
High-vacuum systems operate at pressures far below atmospheric, requiring precise control of leaks and contamination.
2 Critical Applications
Found in semiconductor fabs, space simulations, medical imaging, and scientific research, these systems are vital across industries.
3 The Role of Feedthroughs
Hermetic sealing of all connections to the outside is essential to maintain a high-vacuum environment.
The Function of Vacuum Feedthroughs
What Are Vacuum Feedthroughs?
Feedthroughs are connectors that allow electrical, optical, or mechanical components to pass through the walls of a vacuum system without compromising the vacuum seal.
Types of Feedthroughs
Key Challenges
Electrical feedthroughs (power and signal)
Optical feedthroughs (fiber optic)
Fluid feedthroughs
Preventing gas leakage into the vacuum
Maintaining electrical and thermal insulation
Ensuring long-term durability under extreme conditions
Critical Design Features of Vacuum Feedthroughs
Hermetic Sealing
Feedthroughs must be hermetically sealed to prevent any leaks, even under extreme pressure differentials.
Material Selection
Carefully chosen materials like stainless steel and glass-to-metal seals are essential to withstand thermal and mechanical stresses.
