Alumina substrate, is a special process board in which copper foil is bonded directly to the surface of aluminum oxide (Al2O3) or aluminum nitride (AlN) alumina substrate at high temperature.
What are the uses of alumina substrates?
1, alumina substrate in the chip application
In led more alumina substrate made of chips to achieve better thermal conductivity. In addition, in the following electronic devices also use alumina substrates made of ceramic chips.
◆High power power semiconductor module.
◆Semiconductor cooler, electronic heater; power control circuit, power mixing circuit.
Intelligent power components; high frequency switching power supplies, solid state relays.
◆Automotive electronic, aerospace and military electronic components.
◆Solar panel components; telecommunication special switch, receiving system; laser and other industrial electronics.
2、alumina substrate in the three generations of semiconductor applications
MOSFETs, IGBTs, transistors and other mainstream power devices represented in their respective frequency bands and power supply power band occupy a place. Due to the comprehensive excellent performance of IGBT, has replaced GTR, become the inverter, UPS, inverter, motor drive, high-power switching power supply, especially the now hot electric vehicles, high-speed rail and other power electronic devices in the mainstream of the device.
3, alumina substrate in the field of electronic power applications
In the field of power electronics, such as power switching power supply, power drive, etc., need dielectric alumina substrates to achieve better thermal conductivity, to prevent current burnout and short circuit.
4, alumina ceramic co-firing plate in the lithium battery industry
With the recommendation of artificial intelligence and environmental protection, the automotive industry also launched the electric car, mainly through the battery storage, the use of alumina substrate to do the lithium battery can achieve better current and heat dissipation function, to promote the market demand for new energy vehicles.
5, alumina substrate in the application of integrated circuits small size alumina substrate chip
Through the technology can also achieve small size integrated circuit packaging, so the application of integrated circuits is also increasingly large; after all, integrated circuit development with precision, miniaturization and other characteristics.
