Ceramic PCB

Andwin Circuits provide ceramic PCB for your printed circuit boards needs.

Due to ceramic PCBs have high thermal conductivity and low expansion coefficient (CTE),
Ceramic circuit boards are more versatile, less complex and offer superior performance compared to regular PCBs.

Many users of printed circuit boards find ceramic PCBs have an advantage over traditional boards made of other materials.

  • How many types ceramic pcb substrate material?

There are 2 types ceramic pcb substrate material :

  • Aluminum oxide Ceramic (Al2O3)

  • Aluminum Nitride Ceramic ( AlN )


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

ceramic pcb substrate

Aluminum oxide Ceramic PCB substrate (Al2O3) is white color
Thermal conductivity Min. 24 W/m.k up to 30W/m.k

Aluminum Nitride Ceramic PCB substrate ( AlN ) is brown
Thermal conductivity Min.275 W/m.k up to 320 W/m.k

Aluminum Nitride ceramic PCB substrate have better thermal conductivity,
Also,higher cost, choose a suitable material according your products.

It is important to choose the highly appropriate substrates for your electronic circuits.
There are different kinds of boards available,
but ceramic pcb get more fame among circuit board users because of its versatility.

If you want to get the best kinds of boards, you can contact us.
We offer the most reliable solutions based on the printed circuit boards requirements of
our customers.

The main reason to use these solutions is that they are ideal for all kinds of electronic
circuits which have minimal expansion coefficient and increased thermal conductivity.

With better versatility,
It appears as a perfect alternative to existing printed circuit board boasting of increased
performance and minimal complex design.

It ensures that ceramic pcb work effectively on chip-on-board modules, high-power circuits,
and proximity sensors.

  • How many type of ceramic pcb conductor wire?

General have 4 types of conductor :

  • Copper ( Cu )

  • Silver ( Ag )

  • Gold ( Au )

  • Platinum ( Pt )

1.   Copper conductor:

There are 2 types Copper conductor ceramic PCB

1. DPC – Direct plate copper
-Min. Copper thickness 10um
2 Layers with plated via holes is available.
-work temperature up to 350 degrees Celsius
-( in inert gases up to 850 )

2. DBC – Direct bonded copper
-Min. Copper thickness 100um
-2 Layers with plated via holes is not available.
-work temperatureup to 350 degrees Celsius
-( in inert gases up to 850 )

DBC ( Direct Bonding Copper )  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.

2.   Silver conductor:

Thick film technology
Silver conductor thickness is 10um – 20um
2 layers with via is available
Work temperature up to 350 degrees Celsius

3.   Gold conductor:

work temperature up to 850 degrees Celsius

4.   Platinum conductor:

work temperature up to 850 degrees Celsius

  • 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.
