When to Use Ceramic Feedthroughs

Posted by Kaylyn on

Engineers are often tasked with the job of creating seals around ceramic feedthroughs. Sometimes the seal is as simple as an epoxy or glue. For those situations that require a stronger seal, a mechanical or glass seal is necessary. The ceramic feedthrough is often a vital part of the seal and is used in situations where the highest performance is expected.

The Advantages of Ceramic vs. Glass

Ceramic feedthroughs offer some important benefits, superior resistance to both mechanical and thermal shock, an ability to resist corrosion, and protection from leaks. Glass can resist the effects of temperature changes, fluctuating pressure, and variations in humidity. Ceramic, however, provides better performance. Ceramic-to-metal applications require complicated engineering and typically comes at a higher cost.

Who Uses Ceramic Feedthroughs?

There are some industries that require the high level of performance delivered by ceramic feedthroughs. These industries include the aerospace market, medical implant device manufacturers, and industries using high voltage or current laser applications.

Look for Providers of Great Quality Feedthroughs

Which Is the Best Hermetic Seal: Glass or Ceramic?

Posted by Kaylyn on

If you are in the market for a hermetic seal, you may wonder if it is better to purchase a glass to metal seal or a ceramic to metal seal. Each variety has its respective advantages and disadvantages. Some people prefer to stick with one kind, while others use different seals depending on the function.

Glass to Metal Seal and Feedthrough

A glass to metal seal is made with glass molten right to the metal. This provides an advantage of a secure seal that is connected directly with the metal. Glass is thought of as fragile, but it has a high level of compression strength. It is also a less expensive alternative to ceramic seals.

Ceramic to Metal Seal

A ceramic to metal seal is more costly than a glass to metal seal, and some say the difference in price is worth it. Ceramic can be made in custom designs and show more resistance to mechanical and thermal shocks. However, these seals can have a greater tendency to chip than glass does, but can last longer before these chips form.

Some people swear by their favorite kind of glass to metal seal, while others prefer ceramic. The kind you choose depends on the job you need to do, cost considerations and how much shock you want the seal to withstand.

Understanding Hermetic Seal Types and Uses

Posted by Kaylyn on

A hermetic seal is known as a go-to choice for superior protection when it counts. Whether you require protection from air, gasses, moisture, soil or any other hazard, hermetic connections are the gold standards across many industries. But a seal protects best when it is the right seal for the job. Learn more about the main types of hermetic sealing and find out which ones are best for your job.

To start with, there are three main types of airtight seal. They are:

  • Glass to glass seal
  • Glass to metal seal
  • Ceramic to metal seal

Glass to Glass Hermetic Seals

When two glass pieces require a perfectly sealed environment, glass to glass sealing is the choice. As many as five layers may be involved in the creation this type of seal, which is often used in sealing flat windows, glass tube components and glass envelopes to name just a few applications.

Glass to Metal Seals

Glass and metal fused together to form leak-tight joints are glass to metal seals. These types of seals are all around you every day, due mainly to their versatility and strength.  Known for their exceptional hermetic values, these types of seals are critical in the construction of vacuum tubes, pressure tight glass windows and any number of electronic components to name just a few applications. GTMs are especially useful in the lighting industry, with the most common application being the seal on a lamp bulb.

 Ceramic to Metal Seals

Ceramic to Metal seal is more costly and time consuming to make than a glass to metal seal. Some say it is worth for applications where high operating temperatures, high voltage and harsh environments are required. Ceramic can be made in custom designs and show more resistance to mechanical and thermal shocks.

When zero porosity is required, hermetic sealing is the reliable choice. Know your options by understanding the different sealing possibilities and ensure you’re choosing the best sealing method.

3 Rules for Choosing Hermetic Packages

Posted by Kaylyn on

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.
