Ceramic metal shell and brazing process thereof
The invention provides a ceramic metal shell and a brazing process thereof. The ceramic metal shell comprises a bottom plate and a shell body, the shell body is arranged at the top of the bottom plate, a copper column and a ceramic sealing hole are arranged in the shell body, an insulator, a flat head lead and an insulation heat dissipation module are arranged in the ceramic sealing hole, and the insulation heat dissipation module comprises beryllium oxide ceramic and a molybdenum sheet. According to the ceramic metal shell and the brazing process thereof, the introduced beryllium oxide ceramic has high insulation coefficient, strength and heat conductivity coefficient and is mainly used for integrated circuit substrates, high-power gas laser tubes, packaging shells and the like, beryllium oxide plays an irreplaceable role in application of aviation, spaceflight and military equipment, and the application range of the beryllium oxide ceramic is widened. And the beryllium oxide has good packaging process adaptability, so that the application of the beryllium oxide in packaging pieces is wider and wider.
