Ceramic PCB: ceramic substrate circuit board

Ceramic PCB is a kind of heat conducting ceramic powder and organic binder, and the heat conduction organic ceramic PCB is prepared at a thermal conductivity of 9-20W/m. In other words, ceramic PCB is a printed circuit board with ceramic base material, which is highly thermally conductive materials such as alumina, aluminum nitride, as well as beryllium oxide, which can make a quick effect on transferring heat away from hot spots and dissipating it over the whole surface. What’s more, ceramic PCB is fabricated with LAM technology, which is a laser rapid activation metallization technology. So ceramic PCB is highly versatile that can take place of the entire traditional printed circuit board with a less complicated construction with enhanced performance.

Apart from MCPCB, if you want to use PCB in high pressure, high insulation, high frequency, high temperature, and high reliable and minor volume electronic products, then Ceramic PCB will be your best choice.

Why Ceramic PCB has such excellent performance? You can have a brief view on its basic structure and then you will understand.

• 96% or 98% Alumina (Al2O3), Aluminum Nitride (ALN), or Beryllium Oxide (BeO)
• Conductors material: For thin, thick film technology, it’ll be silver palladium (AgPd), gold pllladium (AuPd); For DCB (Direct Copper Bonded) it’ll be copper only
• Application temp: -55~850C
• Thermal conductivity value: 24W~28W/m-K (Al2O3); 150W~240W/m-K for ALN , 220~250W/m-K for BeO;
• Max compression strength: >7,000 N/cm2
• Breakdown Voltage (KV/mm): 15/20/28 for 0.25mm/0.63mm/1.0mm respectively
• Thermal expansion conefficient(ppm/K): 7.4 (under 50~200C)
