Product Description
Glass-to-metal sealed metal headers are widely used in semiconductor packaging, laser diode modules, sensors, and electronic components requiring hermetic sealing. The package uses a precision glass sealing process that bonds metal and glass together, forming a highly reliable hermetic structure that protects internal electronic components from moisture, gas leakage, and environmental contamination.
The metal body is typically manufactured from Kovar alloy due to its thermal expansion compatibility with glass materials, ensuring long-term stability under temperature cycling conditions. These headers provide excellent insulation resistance, low leak rate, and reliable electrical performance.
They are commonly used in semiconductor devices, optical communication modules, aerospace electronics, industrial sensors, and medical equipment.
