AlN Ceramic Mo Mn Metalized Substrate

The AlN Ceramic Mo Mn Metalized Substrate is a kind of advanced material. It has really good properties and is widely used in the electronics industry.

It's made with aluminum nitride (AlN) ceramic as the base material. AlN has a high thermal conductivity, which is several times higher than that of alumina. That's why it's a perfect choice for getting rid of heat in high-power electronic devices.

Molybdenum (Mo) and manganese (Mn) are used for the metalization process. The Mo Mn metal layer is put on the surface of the AlN ceramic substrate. This layer gives good electrical conductivity and makes sure that there's a reliable connection for electronic components.

When it comes to making the AlN Ceramic Mo Mn Metalized Substrate, there are usually a few important steps. First, high-purity AlN powder is heated at high temperatures to make a dense ceramic substrate. Then, the Mo Mn paste is either screen-printed or sprayed onto the surface of the substrate. After that, it's heated at a certain temperature to make sure that a uniform and well-bonded metal layer is formed.

Performance Advantages

Excellent Thermal Conductivity: The high thermal conductivity of AlN allows for efficient heat dissipation, reducing the temperature of electronic components and improving the reliability and lifespan of the device.

Good Electrical Insulation: AlN ceramic has good electrical insulation properties, which can effectively isolate different electrical signals and prevent electrical leakage and short circuits.

High Chemical Stability: It shows high chemical stability in various harsh environments, resistant to corrosion and oxidation, ensuring the stability of the substrate and the electronic devices using it.

Strong Adhesion of the Metal Layer: The Mo Mn metal layer has strong adhesion to the AlN ceramic substrate, which can withstand mechanical vibrations and thermal cycling without peeling off.

Applications

Power Electronics: It is widely used in power electronic devices such as power amplifiers, power modules, and high-power LEDs. The excellent heat dissipation performance of the substrate can effectively solve the heat problem of these devices and improve their power density and reliability.

Microwave and RF Devices: In microwave and radio frequency (RF) circuits, the substrate's high thermal conductivity and good electrical insulation can meet the requirements of high-frequency signal transmission and heat dissipation. It is often used to make microwave substrates, RF filters, and antennas.

Automotive Electronics: With the increasing demand for automotive electronics reliability and miniaturization, AlN Ceramic Mo Mn Metalized Substrate is used in automotive power electronics, engine control units, and other components to improve the heat dissipation and reliability of automotive electronics.
