Aluminum Nitride Ceramic Substrate Precision Laser Processingmerits
Precision laser processing technology is through the workpiece to be processed on the surface of the local laser heating, so that the material to be processed in the softening of the material area, change the yield strength of the material so that it is less than the fracture strength, to achieve the material removal from brittle damage to the quasi-plastic deformation of the change in the material removal mechanism of the brittle fracture at normal temperatures, so as to achieve the purpose of high-efficiency, high-precision machining of the aluminum nitride ceramic substrate.
Description
Advantages of Precision Laser Processing of Aluminum Nitride Ceramic Substrates
Through the workpiece to be processed surface local laser heating, so that the material to be processed area material softening, change the yield strength of the material so that it is less than the fracture strength, material removal from brittle damage to the transformation of quasi-plastic deformation, change the normal temperature brittle fracture material removal mechanism, so as to achieve the high efficiency, high precision machining of aluminum nitride ceramics purpose.
Applications of Aluminum Nitride Ceramics
Aluminum Nitride (AlN) ceramics have high thermal conductivity and electrical insulation, so they can be used in a variety of electronic devices. Aluminum nitride has a thermal conductivity greater than 170W/(mk), good resistance to thermal shock, and can be used in high temperature environments up to 2200℃. Therefore, aluminum nitride ceramic products are ideal for many industries, such as:
- Radiators and heat sinks
- Electronics Packaging Substrates
- Substrates and insulators for microelectronic and optoelectronic devices
- Laser Thermal Management Components
- electrical insulation
- Molten Metal Fixture
Basic Properties of Aluminum Nitride Ceramics
Aluminum Nitride (AlN) is a covalently bonded compound, atomic crystal, diamond-like nitride, hexagonal crystal system, fibrillated zincite crystal structure, non-toxic, white or off-white.
- High thermal conductivity (>170W/m-K), close to BeO and SiC, more than 5 times that of Al2O3;
- The coefficient of thermal expansion matches that of Si and GaAs;
- Various electrical properties (dielectric constant, dielectric loss, body resistivity, dielectric strength) are excellent;
- Good mechanical properties, higher flexural strength than Al2O3 and BeO ceramics, can be sintered at atmospheric pressure;
- It can be produced by casting process and is a promising substrate and packaging material for high power integrated circuits.
