Aluminum Nitride (AlN) is the best available thermally conductive material (170 W/mK) that is also a strong electric insulator. It is therefore used in a variety of applications where heat
Yellowing has been observed on the Al₂O₃ ceramic portions of Direct Bonded Copper (DBC) substrates, with varying degrees of discoloration. Recently, some customers have expressed concerns that this phenomenon might
Silicon nitride (Si₃N₄) ceramics are compound ceramics formed from silicon and nitrogen elements through high-temperature sintering. Their unique crystal structure and chemical bonds endow them with distinctive physical and chemical
Common alumina ceramics are classified based on their Al₂O₃ content, including variants with 99%, 95%, 90%, 96%, 85%, and sometimes 80% or 75% alumina. 99% alumina refers to alumina with
