Where Can You Find Hermetic Packages?

Electronic components can be quite fragile, which is why it’s important to shield them from unsuitable environments. One way to protect semiconductors and other devices from water and corrosive materials is with an airtight seal around the desired area. To keep technology functioning properly over the long haul, you can often find hermetic packages in some of the harshest conditions known to man.


As an object dives into the ocean, water exudes pressure as it tries to infiltrate the enclosure. When exploring the deepest regions of the sea in search of oil or exotic wildlife, electronic equipment takes a lot of abuse. To protect these sensitive components from damages, scientists trust hermetic packages to provide a watertight barrier.

Outer Space

 As satellites travel in an orbit and probes explore the outer reaches of the solar system, sophisticated equipment transmits information back to the planet. If a semiconductor requires a gas environment to function properly, hermetic packages can keep it from escaping into the vacuum of space.


 Your body is mostly water, which is why pacemakers and other implanted devices need to be sealed against fluid incursion. When your health is on the line, you can trust a tight seal to keep you alive.

Protection for Electronics

These are just a few uses for hermetic packages, but they’re the perfect solution whenever you need to shield sensitive components from harsh environments.

Nowadays, hermetic packages are offering solutions for high reliability and high performance applications so they are extensively used in aerospace, medical and commercial applications.

3 Rules for Choosing Hermetic Packages

Whether in medical, military, aeronautic or any myriad of settings, failure of hermetic headers can have catastrophic outcomes. How can you ensure that your hermetic packages are up to the challenge of your unique hermeticity needs? Here are three ideas to ensure your devices won’t fail.

Hermeticity Testing

Hermeticity testing primarily involves either fine leak testing or gross leak testing. The former examines hermetic packages for defects that can lead to leakage, while the latter focuses on damage that can cause gross package leakage. Periodic testing is a good way to detect faults before a major incident.

Choose the Right Seal

The proper hermetic seals are key to preventing leakage. Glass to metal seals might be best for pressure-tight windows, while glass to glass might be better for glass tube components. When choosing hermetic headers and packages, consider the material you are sealing.

Pick an Experienced Manufacturer

The market for hermetic headers is a broad one and it can be difficult to know which manufacturers are ideal. A good rule of thumb is to find a manufacturer specializing in more than one type or market of hermetics. Choose a company offers a good mix of seal types with hermetic packages designed for various industries. Finally, look for one with a trusted name and years of experience to ensure hermetics you can depend on.
