Should You Consider Epoxy Vacuum Feedthroughs?

For years, designers and engineers were constrained to glass-to-metal and ceramic-to-metal feedthroughs. Epoxy has changed that. Today’s epoxy feedthroughs can conform in ways unfathomable with glass or ceramic. Learn some of the benefits of today’s epoxy vacuum feedthrough. Is it the right choice for your project? Flexibility One of the major benefits of epoxy electrical…

Which Is the Best Hermetic Seal: Glass or Ceramic?

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.…

Understanding Electrical Feedthroughs

Glass-to-metal seals are more effective than O-rings and epoxy when it comes to maintaining an hermetic seal. Sometimes, glass isn’t effective at high voltage or high operating temperatures. The solution is a ceramic-to metal seal and electrical feedthrough. Although there is more labor and time involved in creating this type of seal, it will work…

Getting the Right High Vacuum Feedthrough

A hermetic feedthrough must be secure enough to prevent leakage, even the smallest amount. It has to maintain a vacuum under certain conditions, which are different for every application. Fortunately, there are three main types of feedthroughs which operate in hermetic vacuums:   Low voltage Water-cooled and RF High-voltage   We have the experience to…
