  Ceramic substrate refers to a special process board in which copper foil is directly bonded to alumina(Al2O3)or aluminum nitride(AlN)ceramic substrate surface(single-sided or double-sided)at high temperature.The made ultra-thin composite substrate has excellent electrical insulation properties,high thermal conductivity,excellent solderability and high adhesion strength,and can be etched into various patterns like a PCB board,and has a large current carrying capacity.ability.Therefore,ceramic substrates have become the basic material for high-power power electronic circuit structure technology and interconnection technology.

  Introduction to the characteristics and common uses of ceramic substrates

  Features:

  1.Strong mechanical stress,stable shape;high strength,high thermal conductivity,high insulation;strong bonding force,anti-corrosion.

  2.Good thermal cycle performance,with 50,000 cycles and high reliability.

  3,the same as PCB board(or IMS substrate)can be etched out of various graphic structures;no pollution and no pollution.

  4.The operating temperature is wide-55℃~850℃;the thermal expansion coefficient is close to silicon,which simplifies the production process of power modules.

  Use:

  1.High-power power semiconductor modules;semiconductor refrigerators,electronic heaters;power control circuits,power hybrid circuits.

  2,smart power components;high-frequency switching power supplies,solid state relays.

  3,automotive electronics,aerospace and military electronic components.

  4.Solar panel components;telecommunications dedicated exchanges,receiving systems;industrial electronics such as lasers.

  The advent of ceramic substrate products has opened up the development of the heat dissipation application industry.Due to the heat dissipation characteristics of ceramic substrates,coupled with the advantages of ceramic substrates such as high heat dissipation,low thermal resistance,long life,and withstand voltage,with the improvement of production technology and equipment,product prices have accelerated and rationalized,And then expand the application areas of the LED industry,such as indicator lights for home appliances,car lights,street lights and outdoor large signs.The successful development of ceramic substrates will provide services for indoor lighting and outdoor lighting products,and broaden the future market areas of the LED industry.
