Specification of High Purity Aluminum Nitride Aln for Ceramic Substrate

This High Purity Aluminum Nitride (AlN) ceramic substrate material offers exceptional performance. It features very high purity, typically exceeding 99% AlN content. This purity is critical. Impurities negatively impact key properties. The material delivers outstanding thermal conductivity. Values range from 170 to 220 W/mK. This is much higher than alumina ceramics. Efficient heat dissipation is essential for demanding electronics.

AlN ceramic substrates provide excellent electrical insulation. They have high volume resistivity. This prevents current leakage. The material shows good dielectric strength. It withstands high voltages. The thermal expansion coefficient of AlN closely matches silicon. This is important. It minimizes thermal stress when bonded to silicon chips or devices. Reliability improves significantly.

The material possesses high mechanical strength. It is hard and rigid. This allows handling thinner substrates. Thinner substrates aid miniaturization. AlN resists chemical attack well. It performs reliably in harsh environments. This includes high temperatures and corrosive atmospheres. The material is non-toxic. It meets safety standards for electronic use.

Manufacturing processes ensure consistent quality. Tight control guarantees purity and properties. Applications include power modules, LED packages, and semiconductor equipment. AlN substrates handle high heat loads. They are ideal for high-power density circuits. Laser cutting and precision machining are possible. This achieves exact dimensions and tight tolerances. Surface finishes are available for metallization. This ensures strong bonds for circuit layers.

Applications of High Purity Aluminum Nitride Aln for Ceramic Substrate

High purity aluminum nitride ceramic substrates offer significant advantages in demanding electronics. This material handles heat extremely well. Electronic components generate heat during operation. This heat must go somewhere. Aluminum nitride moves heat away efficiently. It prevents dangerous temperature buildup. That protects sensitive parts. It also keeps performance stable. You see this in high-power LED lighting. Bright LEDs create intense heat. Aluminum nitride substrates manage that heat. They ensure long LED life and consistent light output. Power electronics use these substrates too. Think of electric vehicle systems or industrial motor drives. These applications push high currents. Aluminum nitride keeps power modules cool. That means better reliability and smaller designs.

RF and microwave devices benefit similarly. Signals travel fast. Heat is a problem again. Aluminum nitride provides a stable, low-loss platform. Signal integrity stays high. Another key point is thermal expansion matching. Materials expand when hot. Aluminum nitride expands at a rate close to silicon. Silicon is the base for most chips. This matching reduces stress. Connections between chip and substrate stay strong. It prevents cracking or failure. Electrical insulation is another vital feature. Aluminum nitride stops unwanted current flow. It isolates circuits safely even at high voltages. This combination is powerful: excellent heat spreading, good expansion match, and strong electrical isolation. Manufacturers choose aluminum nitride for critical thermal management tasks. It enables smaller, more powerful, and reliable electronic systems. Its performance is crucial where standard materials fall short.
