Overview of aluminum nitride ceramics

Aluminum Nitride Ceramic is an advanced ceramic material with aluminum nitride as the main component. It has been widely used in electronics, optics, and mechanics due to its unique properties.

Features of aluminum nitride ceramics

High thermal conductivity: Aluminum nitride ceramics have relatively high thermal conductivity, usually between 170-260 W/m·K, which makes it an excellent heat dissipation material. It is especially suitable for electronic devices that require efficient heat dissipation, such as substrate materials for power semiconductor devices.

Good electrical insulation: Despite its high thermal conductivity, aluminum nitride ceramics are excellent insulators of electricity, which can effectively prevent current leakage and ensure the safe operation of electronic components.

Low dielectric constant and dielectric loss: These characteristics make aluminum nitride ceramics very suitable for use in high-frequency circuits because it can reduce energy loss during signal transmission.

High temperature resistance: Aluminum nitride ceramics can maintain structural stability and strength at extremely high temperatures. Its melting point is about 2800°C, so it is suitable for applications in high temperature environments.

Low thermal expansion coefficient: Compared with semiconductor materials such as silicon, aluminum nitride has a lower thermal expansion coefficient, which means it has better dimensional stability when the temperature changes, which helps improve packaging reliability.

Corrosion resistance: Aluminum nitride ceramics have good chemical stability to most molten metals and are not easily oxidized or corroded, allowing them to perform well in harsh environments.

High mechanical strength: Although not as hard as some other types of ceramic materials, aluminum nitride ceramics still provide enough mechanical strength to allow them to be used in many structural applications.

Specifications of High thermal conductivity thick film aln aluminum nitride ceramic pcb and alumina pcb substrate

High thermal conductivity thick movie light weight aluminum nitride (AlN) ceramic PCBs and alumina (Al ₂ O TWO) PCB substrates serve crucial duties in advanced electronic devices. Both materials master managing warmth and guaranteeing reliability sought after atmospheres. AlN ceramic PCBs attract attention for their extraordinary thermal conductivity, usually ranging in between 170-200 W/mK. This makes them optimal for high-power applications where warm dissipation is essential. Alumina substrates supply reduced thermal conductivity, around 24-28 W/mK, yet stay widely used due to their cost-effectiveness and robust efficiency in standard problems.

Electrical insulation is a key attribute of both materials. AlN and alumina substrates give high dielectric strength, avoiding present leakage also under high voltage. This ensures secure procedure in circuits calling for specific electrical seclusion. Mechanical strength is another benefit. Alumina substrates are recognized for high sturdiness and resistance to physical anxiety, making them ideal for harsh settings. AlN, while a little much less mechanically durable than alumina, maintains sufficient stamina for most applications while outshining in thermal management.

Temperature level security is important. AlN substrates hold up against operating temperature levels as much as 850 ° C, while alumina manages slightly greater arrays, around 1600 ° C. Both materials resist thermal development inequalities, decreasing the danger of delamination or fracturing throughout rapid temperature changes. Thick movie modern technology boosts these substratums. Conductive traces are screen-printed making use of specialized pastes, allowing precise circuit patterns. This procedure makes sure compatibility with high-temperature soldering and wire bonding.

Surface surfaces vary. AlN PCBs typically use gold or silver finishes to boost conductivity and corrosion resistance. Alumina substratums may employ more affordable finishes like copper or nickel, balancing performance and expense. Applications differ based upon demands. AlN is preferred in high-power LED components, RF/microwave devices, and automotive power electronics. Alumina matches customer electronics, industrial sensing units, and less thermally intensive systems.

Price stays a determining element. Alumina substratums are much more cost effective, appealing for budget-sensitive projects. AlN’s superior thermal performance justifies its greater price in specialized applications. Both materials sustain miniaturization and high-density layouts, meeting the demands of contemporary electronics. Compatibility with automated setting up procedures makes certain simplicity of combination right into assembly line.
