Shaanxi Puwei Electronic Technology Co., Ltd. — HTCC (High-Temperature Co-Fired Ceramic) substrates are advanced ceramic base materials created by printing high melting point metal pastes such as tungsten, molybdenum, or molybdenum-manganese onto 92–96% alumina ceramic green tapes. These are then laminated with sintering additives and co-fired at 1500–1600°C. The result is a robust, efficient, and thermally stable ceramic structure widely used in electronics.
What Makes HTCC Unique?
HTCC substrates are valued for their corrosion resistance, high-temperature stability, long service life, and excellent thermal conductivity. Their uniform temperature distribution and fast heat compensation make them ideal for high-performance applications.
Advantages and Limitations
- High mechanical strength
- Excellent thermal conductivity
- Stable chemical properties
- High wiring density
Cons:
- Limited electrical conductivity of refractory metals
- Cannot directly print resistors
- Relatively high production cost
Key Application Areas
1.Ceramic Heaters
HTCC ceramic substrates are energy-efficient alternatives to PTC ceramic heaters. They are widely used in hair dryers, portable heaters, thermal plates, heated toilet seats, medical warmers, and infrared therapy devices.
2.Multilayer Ceramic Substrates
Due to their mechanical and thermal advantages, HTCC substrates are ideal for high-reliability microelectronic circuits and power electronic modules in automotive and industrial fields.
3.Ceramic Packages
HTCC tubes and housings are crucial in electronic packaging for components such as vacuum tubes, power switches, and semiconductor chips. The high-temperature sintering process ensures excellent insulation and durability.
