Complex high-precision aluminum nitride ceramics

In the vast field of materials science, aluminum nitride (AlN) ceramics have become an indispensable key material in modern high-tech fields due to their excellent thermal conductivity, excellent insulation performance, good mechanical strength, and chemical corrosion resistance. However, when strict requirements are placed on size, shape, and tolerance in application scenarios, ordinary aluminum nitride ceramics are difficult to meet the demands. Our ‘complex high-precision aluminum nitride ceramics’ are designed to address these challenges, and they are not just a material, but also a precise solution.

The complex high-precision aluminum nitride ceramics we provide are based on traditional aluminum nitride ceramics and achieve ultimate control over product geometry, dimensional accuracy, and surface smoothness through a series of cutting-edge manufacturing processes. We are able to manufacture aluminum nitride ceramic components with complex three-dimensional structures, small feature sizes, and extremely narrow tolerances (up to micrometer level). From precision heat sinks at the micrometer level to complex sensor bases, from irregularly shaped packaging shells to electronic substrates with fine flow channels, we can create them with precision. This material not only maintains the inherent excellent properties of aluminum nitride, but also endows the product with unprecedented precision and functionality, enabling it to be perfectly integrated into cutting-edge systems that require extremely high space, heat dissipation, and signal integrity.

Detailed explanation of product features:
Excellent thermal management capability: Aluminum nitride ceramics have a thermal conductivity of up to 120-220 W/(m · K) (far exceeding alumina ceramics), which can efficiently conduct the heat generated by high-power electronic devices quickly, effectively reduce device operating temperature, improve system stability and reliability, and extend service life.
Excellent electrical insulation: With extremely high dielectric strength and low dielectric constant, it is an ideal electrical insulation material that can effectively isolate high voltages, reduce losses and crosstalk in signal transmission, and ensure the normal operation of electronic systems.
High mechanical strength and hardness: Aluminum nitride ceramics have excellent mechanical strength, hardness, and wear resistance, and can withstand certain mechanical stress and impact, ensuring the structural integrity of components in complex working environments.
Good chemical stability: It has good corrosion resistance to most acids, bases, and salts, and can maintain stable performance even in harsh chemical environments.
Dimensional accuracy and complex shapes: The core advantage lies in the ability to achieve complex three-dimensional structures and high-precision dimensional control. We use advanced technologies such as precision molding, isostatic pressing, injection molding, precision machining (such as CNC milling, grinding, EDM, etc.), and special connections (such as laser welding, brazing) to ensure that our products meet strict design tolerance requirements and can achieve complex geometric shapes that are difficult to achieve with traditional processes.
High surface smoothness: High smoothness surfaces can be provided according to requirements, reducing contact thermal resistance, improving heat dissipation efficiency, or meeting specific application needs such as optics and sealing.
Low coefficient of thermal expansion: The thermal expansion coefficient is close to that of semiconductor materials such as silicon (Si), making it an ideal material for semiconductor device packaging and substrate, which can effectively reduce stress caused by thermal mismatch and improve packaging reliability.

Application area
Complex high-precision aluminum nitride ceramics, with their unique performance combination, are widely used in cutting-edge technology fields that require extremely high performance, size, and reliability:
High power electronic device packaging: substrates, heat dissipation substrates, and insulation bases for wide bandgap semiconductor devices such as IGBT modules, power MOSFETs, SiC/GaN, etc. Its high thermal conductivity and thermal expansion coefficient matched with silicon are the key to achieving efficient and highly reliable power packaging.
Radio frequency (RF) and microwave components: substrates, antenna covers, filters, packaging shells, etc. used for manufacturing high-frequency circuits. The low dielectric constant and low loss characteristics ensure efficient signal transmission and low loss.
Sensors and actuators: As the base or structural components of sensitive elements, they are used to manufacture pressure sensors, temperature sensors, accelerometers, etc. in high temperature, high humidity, and corrosive environments. Its insulation, heat resistance, and mechanical stability are key factors in ensuring sensor accuracy.
Laser and Optoelectronic Integration: Used as a heat dissipation substrate for high-power laser diodes (LDs) and a support structure for optical devices. Efficient heat dissipation can significantly improve the output power and lifespan of lasers.
Micro Electro Mechanical Systems (MEMS): Used to manufacture the base, housing, or partial structural layers of MEMS devices that require high precision and reliability.
Aerospace and Defense: Structural and heat dissipation components used in the manufacturing of radar system components, electronic countermeasures equipment, and satellite communication devices, requiring materials to maintain high performance even in extreme temperature and mechanical environments.
Medical equipment, such as high-intensity ultrasound transducers and high-frequency electronic components in medical imaging equipment, requires materials with good biocompatibility (or easy handling), good heat dissipation performance, and precise dimensions.
High end thermal management solutions, such as CPU/GPU heat dissipation substrates, heat sinks for LED lighting modules, and vapor chamber structural components for high-density integrated circuits, especially for situations that require irregular or small heat dissipation channel designs.
