Premium Wholesale Metal Core Ceramic PCB with Al203 & Ain

Product Description

Ceramic circuit boards are actually based on electronic ceramics, include the material of Alumina Nitride (AlN) , Alumina (Al2O3), BeO, Quartz , Sapphire, Silicone Carbide(SiC) , Silicone Nitride(Si3N4) , Yttria(Y2O3) or Magnesia(MgO) partially stabilized Zirconia(Y-PSZ/Mg-PSZ), 
can be made of various shapes. Among them, the ceramic circuit board has the most outstanding characteristics of high temperature resistance and high electrical insulation performance. It has the advantages of low dielectric constant and dielectric loss, high thermal conductivity, good chemical stability and close to the thermal expansion coefficient of the components. The fabrication of ceramic circuit board will use LAM technology, that is, laser fast activation metallization technology. Applications in the field of LED, high power semiconductor modules, semiconductor refrigerators, electronic heaters, power control circuits, power hybrid circuits, intelligent power components, high frequency switching power supplies, solid state relays Automotive electronics, communications, aerospace and military electronic components.
Ceramic materials have excellent high frequency and electrical properties, high thermal conductivity, excellent chemical stability and thermal stability, etc. It is an ideal packaging material for new generation large scale integrated circuits and power electronic modules.
1. Higher thermal conductivity
2. More matching coefficient of thermal expansion
3. A firmer, less resistive metal film.
4. The solderability of the substrate is good and the use temperature is high.
5. Good insulation
6. Low loss at high frequency
7. High density assembly
8. Free of organic components, cosmic ray resistant, high reliability in aerospace, long service life
9. Copper layer does not contain oxide layer, can be used in reductive atmosphere for a long time
