What is ceramic PCB ?

Ceramic pcb is combination of ceramic substrate and conductor.

There are 2 types ceramic substrate material :

  • Aluminum oxide Ceramic (Al2O3)

  • Aluminum Nitride Ceramic

Always there are called aluminum oxide Ceramic pcb or Aluminum Nitride Ceramic pcb

General have 4 types of conductor:

  • Copper ( Cu )

  • Silver ( Ag )

  • Gold ( Au )

  • Palladium ( Pd )

Andwin Circuits know ceramic PCB well
And have high technologly skill to
Manufacture high quality Ceramics PCB for customers Worldside.

We have capability to make single sided ceramic pcb and double sided ceramic pcb with plate via holes.

Advantage of ceramic PCB

1.  High thermal conductivity property and low thermal resistance,
     Could increase the efficiency and operation lifetime of semi- conductor chips.

2.  Excellent thermal cycling performance and fine mechanic strength.

3.  High isolating strength

4. The thermal expansion coefficient is close to that of the silicon chip.

5. Strong current conductive ability

6. Fine environment compatiblity,no environment contaminative elements,
    Such as PB,Hg and  Cr,etc. 

    Be able to pass strict environment protection credentials.

Material of ceramic pcb

1High Performance with 96% Al2O3 for thick film circuit

Ideal for power electronics in conjunction with
Direct copper bonding (DCB) and active metal brazing (AMB)

99.6% Al2O3 for thin film Circuit

With its extremely fine surface quality, this ceramic material is designed
Especially to meet the highest demands in thin-film technology.

Aluminum Nitride Ceramics PCB

Achieving maximum performance in the smallest possible space inevitably
causes electronic components to develop increasingly high temperatures.
This heat must be dissipated quickly and reliably in order to protect the valuable components,
This is where aluminum nitride ceramics set the benchmark.

 DBC ( Direct Bonding Chips )  Ceramic + copper foil  circuits board

DBC heat-sinking substrate for solar battery is fabricated
by using bonding technology under high temperature.

The conjunction between copper foils and ceramic is molecular
bond and any adhesion agent is not being used.

Due to the fine adhesion between copper foils and ceramic plate.
it can suffer from strict thermal cycling test.

under the normal  temperature environment,the islation performance and material
strength can hold several hundred thousand hours stability.
Other materials can not compare to this on.

Because the ceramic material has fine thermal conductive preperty
the compound material has low resistance.

In the succeeding processes,by the photoresist and chemical etching methods and fine laster cutting process.

DBC heat-sinking substrate for solar battery possesses various accurate
and complex patterns and outlines.
