At Hermetix, we take pride in offering high-quality kovar packages, specifically designed to meet the demands of industries requiring reliable hermetic sealing solutions. Our kovar packages feature a glass-to-metal seal and various unique specifications, ensuring exceptional performance and longevity. In this article, we will delve into the features, dimensions, and applications of our kovar packages, demonstrating why Hermetix is the brand of choice for superior glass-to-metal sealed enclosures.


Glass-to-Metal Seal Technology

Hermetix’s kovar packages are manufactured using advanced glass-to-metal seal technology. This sealing mechanism ensures a robust and airtight enclosure, effectively protecting sensitive electronic components from external factors such as moisture, temperature fluctuations, and mechanical stress. The glass-to-metal seal provides excellent electrical and thermal conductivity, making it an ideal choice for a wide range of applications.


Unique Specifications and Construction

Our kovar packages are designed to meet specific industry requirements. We offer a 54-lead kovar package with a fiber optic channel, allowing for seamless integration of fiber optic components. Additionally, assembly eyelids provide further protection against contaminants while facilitating easy access for maintenance and repairs. With an Au finishing, our kovar packages not only offer corrosion resistance but also ensure excellent solderability for efficient assembly processes.


Dimensions and Important Tolerances

Hermetix’s kovar packages exhibit precise dimensions to fit the needs of diverse applications. The package dimensions are L:68mm, W:66mm, H:12.75mm, ensuring compatibility with standard electronic components. It is essential to note that our kovar packages adhere to strict manufacturing tolerances, with unspecified tolerances being ±0.2mm. These precise dimensions guarantee proper fitment and alignment of components, enhancing overall performance.


Insulation Resistance and Hermeticity

We understand the criticality of insulation resistance and hermeticity in electronic enclosures. Our kovar packages boast an insulation resistance of ≥1× 1010 Ω (500V DC), ensuring excellent electrical isolation between components. Additionally, their hermeticity is ≤1 x 10-3 Pa * cm3/s, guaranteeing a high level of protection against moisture or other external contaminants that could compromise the performance of the enclosed electronics.
