BRAZING METHOD AND DEVICE FOR GLASS KOVAR COMBINATION AND OXYGEN-FREE COPPER

摘要

The invention discloses a brazing method for a glass Kovar combination and an oxygen-free copper, wherein the glass Kovar combination, the silver-based solder and the oxygen-free copper are placed within a quartz room with the pressure of 3.0×10⁻⁵˜7.0×10⁻⁵ Pa. The quartz room is heated by the coils of the high-frequency induction power; and the quartz room stops being heated quickly until reaching the melting temperature of the silver-based solder and then being cooled. The invention further discloses a corresponding brazing device, which simplifies the processing technology in the electronic vacuum industry, reduces the rejection rate greatly, has significant industrial economic value and is the important method of the energy conservation and environment protection. It enables the brazing process time to be short; the energy consumption to be reduced; the whole brazing process to be visible; the temperature to be monitored; and the manufacturing cost to be greatly reduced.
