About ceramic PCB

aluminum nitride ceramic pcb

The types of ceramic pcb substrates:

high temperature fusion ceramic substrate (HTFC)

low temperature co-fired multilayer ceramic (LTCC)

high temperature co-fired multilayer ceramic (HTCC)

direct bonding copper substrate (DBC)

Direct Copper Plating (DPC)

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.

This product is composed of a noble metal consisting of high-conductivity dielectric circuit and high thermal conductivity of insulating material combination of high thermal conductivity substrate. Can effectively solve the problem of low thermal conductivity of PCB and aluminum plate. To effectively heat the heat generated by the electronic components derived to increase component stability and extend the service life.

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 (AIN), 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 AIN , 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)

Ceramic pcb is also a branch of the printed circuit board, ceramic substrate and CEM material substrate, FR-4 substrate is parallel, the production process is same, but the support material is not the same, so there is no substitute circuit board argument.

Now more than 90% of the market are FR-4 materials, the proportion of ceramic substrate is relatively small, and will not become mainstream.
