Vacuum Feedthroughs for High-Integrity Sealed Systems

Posted by admin on

Why Vacuum Feedthroughs Are Essential

Vacuum feedthroughs allow electrical, optical, fluid, or mechanical transfer into or out of a sealed vacuum chamber without compromising the chamber’s integrity. They are crucial in semiconductor processing equipment, scientific research instruments, aerospace simulation chambers, and industrial high-temperature vacuum furnaces. Even the slightest leak can affect process quality, research accuracy, or equipment performance—making hermetic sealing absolutely essential.

Design Requirements for High-Vacuum Environments

Vacuum feedthroughs require materials that tolerate thermal expansion, pressure gradients, plasma exposure, outgassing, and radiation. Complete Hermetics engineers each feedthrough using precision glass-to-metal or ceramic-to-metal bonds calibrated to maintain ultra-low leak rates under severe operating conditions. These feedthroughs maintain performance from cryogenic to extreme high-temperature environments.

Configurations & Materials

Vacuum, electric, glass, and ceramic feedthroughs—often used interchangeably—serve the same core purpose: to route electrical current into or out of a hermetic or vacuum system while preventing any gas leakage. Complete Hermetics designs and manufactures custom glass-to-metal and ceramic-to-metal feedthroughs, including multi-pin and bulkhead hermetic feedthroughs that provide multiple electrical paths through a single flange. Available in laser-weld or solder-in styles, these feedthroughs deliver reliable performance in harsh environments. They are widely used in submersible pumps, downhole drilling tools, exploration instruments, implantable medical devices, and cryogenic surgical probes, where stable electrical continuity and long-term hermeticity are mission-critical.

Applications in High-Tech Sectors

Vacuum feedthroughs support:

  • Plasma etching & PVD/CVD semiconductor tools
  • Space environment simulation chambers
  • Ion beam accelerators & laboratory research equipment
  • Industrial furnaces & metallurgical processing
  • Aerospace test stands requiring high vacuum integrity

Testing & Verification

Every feedthrough undergoes low-helium-leak testing, electrical resistance measurement, thermal cycling, and long-duration vacuum compatibility validation. These processes guarantee reliability in systems where contamination or pressure loss cannot be tolerated.

Medical Hermetic Seals for Life-Critical Electronic Devices

Posted by admin on

Why Hermetic Seals Are Essential

Medical hermetic seals play a critical role in ensuring the safety, reliability, and biocompatibility of implantable and diagnostic electronics. When devices operate inside the human body or are exposed to sterilization processes, they must withstand moisture, bodily fluids, chemical exposure, and extreme thermal variations. Even the smallest leak can cause internal corrosion, signal failure, or biological contamination. As modern medical devices become smaller yet more capable, the demand for advanced hermetic sealing technologies grows significantly.

Glass-to-Metal & Ceramic-to-Metal Sealing Technologies

Complete Hermetics designs medical-grade seals using glass-to-metal (GTM) and ceramic-to-metal (CTM) sealing methods. Glass seals provide cost-effective, high-strength bonding between metal housings and conductive pins, while ceramic seals are ideal for high-voltage or long-term implants due to their exceptional dielectric strength. Using materials such as titanium, stainless steel, and high-purity alumina ceramics, these seals are engineered to perform reliably in demanding biological environments.

Regulatory-Ready Testing & Biological Safety

Medical hermetic seals must meet FDA, ISO 14708, IEC 60601, and biocompatibility standards. Complete Hermetics performs rigorous testing—including helium leak detection, sterilization simulation, thermal shock, electrical insulation analysis, and X-ray inspection—to ensure every seal meets life-critical reliability requirements. Traceability, cleanliness, and manufacturing consistency are maintained at every step.

Applications in Modern Healthcare

Medical hermetic seals enable secure operation in:

  • Pacemakers & implantable cardioverter defibrillators (ICDs)
  • Neurostimulation & pain-management implants
  • Implantable batteries & power modules
  • Surgical navigation tools
  • Diagnostic imaging equipment
  • Long-term biosensor implants

Hermetic Feedthroughs for High-Reliability Sealing

Posted by admin on

What Are Hermetic Feedthroughs?

Hermetic feedthroughs are essential components that allow electrical signals, power, or data to pass through sealed enclosures without allowing any external elements—such as gas, fluid, vapor, or contaminants—to enter. These components are vital in aerospace avionics, semiconductor fabrication, medical implants, power systems, defense platforms, and industrial vacuum equipment. When systems are exposed to high pressure, vacuum, radiation, corrosive chemicals, or temperature fluctuations, hermetic feedthroughs act as the primary barrier protecting internal electronics and maintaining long-term operational stability.

How Hermetic Feedthroughs Maintain Airtight Integrity

A high-performance hermetic feedthrough is created through glass-to-metal or ceramic-to-metal sealing, a process in which insulating materials bond molecularly with the metal shell and internal pins. By carefully matching the coefficient of thermal expansion between materials, Complete Hermetics ensures the seal remains tight even under vibration, pressure cycling, and thermal shock. This engineering precision prevents micro-cracks, corrosion pathways, and seal degradation—factors that can cause catastrophic system failure.

Advanced Materials for Maximum Performance

Hermetic feedthroughs are constructed using specialized alloys such as Kovar, stainless steel, Inconel, and titanium, each chosen for its thermal stability and mechanical resilience. High-purity ceramics offer exceptional dielectric strength, while plating finishes—gold, silver, or nickel—enhance conductivity and corrosion resistance. These materials allow feedthroughs to survive extremely harsh operating environments, from deep-space vacuum to high-pressure oceanic applications.

Applications Across Industries

Hermetic feedthroughs are indispensable in:

  • Satellite propulsion and orbital control systems
  • Semiconductor vacuum etching and deposition chambers
  • Medical imaging, diagnostics, and implantable electronics
  • High-temperature industrial furnaces
  • Defense communication & targeting systems
  • Cryogenic and high-voltage environments
