insulating Al2O3 Aluminiumoxidkeramik ceramic parts
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
The ceramic substrate refers to a special process plate in which a copper foil is directly bonded to a surface of an alumina (Al 2 O 3 ) or aluminum nitride (AlN) ceramic substrate (single or double sided) at a high temperature. The ultra-thin composite substrate produced has excellent electrical insulation properties, high thermal Aluminum Nitride Ceramic conductivity, excellent solderability and high adhesion strength, and can etch various patterns like a PCB board, and has a large current carrying current. ability. Therefore, ceramic substrates have become the basic material for high-power power electronic circuit structure technology and interconnection technology.
Features:
◆ Strong mechanical stress, stable shape; high strength, high thermal Aluminum Nitride Ceramic conductivity, high insulation; strong bonding, anti-corrosion.
◆ Better thermal cycle performance, the number of cycles is up to 50,000 times, and the reliability is high.
◆It can etch various graphic structures like PCB board (or IMS substrate); it is non-polluting and pollution-free.
◆The use temperature is wide -55 °C ~ 850 °C; the thermal expansion coefficient is close to silicon, simplifying the production process of power modules.
Alumina substrate is the most commonly used substrate Aluminum Nitride Ceramic material in the electronics industry. It has high mechanical and thermal properties and high chemical stability compared to most other oxide ceramics. Technical manufacturing and different shapes. Slyton Alumina substrates are already available for 3D customization.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
