1. Electronic device packaging: Kovar is widely used in the packaging of semiconductor devices, integrated circuits, and other electronic components to provide stable packaging and protect electronic components from environmental influences.
2. Optoelectronics: Kovar finds widespread application in lasers, photodetectors, and other optical components due to its excellent thermal expansion coefficient and stability.
3. Aerospace: Kovar is widely used in guidance systems, navigation systems, and other devices in the aerospace field due to its high strength, corrosion resistance, and high-temperature resistance.
In summary, Kovar finds wide applications in the packaging of electronic components or protection of optoelectronic components due to its thermal expansion coefficient that matches that of borosilicate glass.
