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 Bulkhead Feedthroughs for Secure System Penetrations

Posted by admin on

What Are Bulkhead Feedthroughs?

Hermetic bulkhead feedthroughs are specialized sealing components that permit electrical conductors to pass through pressure boundaries while maintaining an absolute airtight separation between two environments. These components are essential for systems where internal integrity must not be compromised—such as vacuum chambers, propulsion systems, laboratory reactors, marine equipment, and industrial process vessels.

How Bulkhead Feedthroughs Maintain Integrity

Bulkhead feedthroughs must withstand intense mechanical stress, extreme temperatures, pressure cycling, chemicals, radiation, and vibration. Complete Hermetics engineers these feedthroughs using robust glass-to-metal and ceramic-to-metal sealing technologies that ensure leak rates as low as 1×10-8 cc/sec. These seals resist cracking, corrosion, and long-term fatigue.

Configuration & Mounting Options

Vacuum, electric, glass, and ceramic feedthroughs—terms often used interchangeably—serve the essential function of carrying electrical current into or out of a hermetic or vacuum system while maintaining an airtight seal. Complete Hermetics designs and manufactures custom glass-to-metal and ceramic-to-metal feedthroughs engineered to prevent gas transmission through pressure barriers.

The company also produces multi-pin hermetic feedthroughs and bulkhead electrical feedthroughs, which route multiple electrical paths through a single flange-mounted bulkhead. Available in laser-weld or solder-in configurations, these feedthroughs are built for extreme environments. They are used in submersible pumps, downhole drilling tools, exploration devices, implantable medical systems, and cryogenic surgical probes, where long-term electrical continuity and hermetic integrity are essential.

Industry Applications

Bulkhead feedthroughs are widely used in:

  • Aerospace propulsion and environmental testing
  • Subsea robotics & marine exploration vessels
  • Cleanroom vacuum chambers & semiconductor tools
  • High-pressure reactors and cryogenic systems
  • Defense-grade electronics and hardened enclosures

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

Custom Engineering Expertise

Every environment demands unique electrical, mechanical, and thermal characteristics. Complete Hermetics provides fully customized feedthrough solutions—with tailored pin counts, geometries, voltage ratings, sealing materials, and mounting styles. Engineers collaborate with customers throughout design, prototyping, and qualification to ensure maximum performance.
