Machining Method Of Aluminum Nitride Ceramic Heat Sink


Aluminum nitride ceramic substrate has excellent thermal conductivity (5-10 times that of alumina self-ceramic), low dielectric constant and dielectric loss, reliable insulation performance, excellent mechanical properties, non-toxic, high temperature resistance, It is resistant to chemical corrosion and has a thermal expansion coefficient similar to that of silicon. It is widely used in sub-communication devices, high-brightness LEDs, power electronic devices and other industries.

Aluminum Nitride Ceramic Machining Form

  • According to customer requirements, the surface can be metallized with gold plating, silver plating, copper plating and other metals, and its thermal conductivity is better.
  • Conventional ceramic products can be polished (single and double-sided polishing can be performed). The surface finish after polishing is Ra: 0.02-0.05μm, and there is no hole phenomenon.
  • Other machining methods can be processed according to the customer’s drawing requirements.

Processing Form Of Aluminum Nitride Ceramic Products:

  • Mould-opening machining: All products except laser machining require mould-opening machining.
  • Laser machining products: according to customer requirements, laser products (aluminum nitride, alumina, aluminum nitride, etc.) are used for scribing, drilling and slotting machining. The minimum diameter of laser drilling is 0.05mm, and the thickness of laser cutting is less than 2mm. , its products have high machining precision and good repeatability.

Applications

Aluminum nitride ceramic substrates are widely used in hybrid integrated circuit interconnect substrates, microwave devices, optoelectronic communications, sensors, MCM and other fields. Including optoelectronic device substrates, ceramic carriers, laser carriers, chip capacitors, chip power dividers, sensors, also referred to as capacitors and spiral inductors.

Aluminum nitride ceramic is a ceramic material mainly based on aluminum nitride. It is widely used in daily life and has the advantages of high temperature resistance, high hardness, corrosion resistance, oxidation resistance and low thermal expansion coefficient.

Because the hardness of aluminum nitride ceramics is very good, it is difficult to process with ordinary CNC machine tools. Pintejin ceramics has been machining ceramics for many years, and CNC machine tools that process ceramic materials are used for machining.

How does this machine work? It is designed for machining ceramic materials, which can effectively improve the efficiency of processed products and ensure the quality of products.
