What Are Kovar Packages?


Kovar is a nickel-cobalt ferrous alloy that was developed to have a coefficient of thermal expansion (CTE) similar to that of glass. This makes it an ideal material for use in electronic packages that house sensitive components, as it can help to reduce stress on the components due to temperature changes. Additionally, kovar offers excellent mechanical properties, making it a popular choice for hermetic packages that need to withstand harsh operating conditions.
