Silicon Nitride PCB (Si₃N₄) – Under Development

A next-generation ceramic PCB with approximately twice the fracture toughness of alumina (Al₂O₃). Its superior resistance to cracking overcomes one of the key limitations of conventional ceramics. The material also maintains its mechanical strength at high temperatures, providing excellent reliability and long-term cost performance.

Key Features

High heat resistance (over 300°C)
High thermal conductivity (85 W/m·K)
Low coefficient of thermal expansion (2.8 × 10⁻⁶/K)
Excellent chemical and solvent resistance
High design flexibility, including three-dimensional PCB structures
Inorganic material
