Product Description

HTCC ALN Aluminium Nitride Ceramics Heating Sheet From China

High-Temperature Co-Fired Ceramic (HTCC) and Low-Temperature Co-Fired Ceramic (LTCC) modules are essential in advanced semiconductor packaging,

requiring materials that offer both thermal efficiency and process compatibility. Our AlN special-shaped parts, crafted from 170 W/(m·K) thermal conductivity

AlN ceramic boards, are designed to integrate seamlessly into HTCC/LTCC manufacturing processes. These custom-machined components—including via holes,

cavities and interconnection structures—exhibit excellent sintering properties and dimensional stability, ensuring precise integration with other packaging materials.

Their high thermal conductivity facilitates efficient heat dissipation in multi-layer modules, while their chemical inertness prevents reactions with other components during firing. Customizable to meet diverse module designs, our AlN special-shaped parts enhance the thermal and electrical performance of HTCC/LTCC packages,

supporting the miniaturization and high-integration of semiconductor devices.
