High-temperature co-fired ceramics (HTCC) mainly use aluminum oxide or aluminum nitride green ceramic ribbons and high-melting-point metal slurries such as tungsten, molybdenum, and manganese as the main raw materials. They are printed by screen printing. The slurry is printed on the green porcelain tape to form a metal circuit, and through-hole filling is used to conduct the upper and lower layers, and then multi-layer lamination and high-temperature sintering are performed (the sintering temperature of aluminum nitride HTCC is above 1800°C, and the aluminum oxide HTCC The sintering temperature is above 1500℃), and finally undergoes electroplating, welding and other processes to form a monolithic structure of a three-dimensional wiring system, which has corrosion resistance, high-temperature resistance, long life, high efficiency and energy saving, uniform temperature, good thermal conductivity, and thermal compensation speed Advantages of waiting quickly.
