More knowleage about ceramic PCB

What is ceramic PCB?

Ceramic PCB (Printed Circuit Board) is a type of circuit board made of ceramic materials
such as alumina,aluminum nitride, Silicon nitride (SI3N4),Beryllium Oxide,Boron Nitride,
Silicon Carbide and Zirconia etc.

alumina ceramic pcb

These materials have high thermal conductivity and excellent electrical insulation properties,
Making them suitable for high-power and high-frequency applications.

Ceramic PCBs are commonly used in electronic devices such as laser device, power modules,
LED lighting, and microwave devices.

They are also known for their durability, reliability, and resistance to thermal and mechanical stress.

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.

  • DPC ceramic PCB
  • DBC ceramic PCB
  • Thick film ceramic circuit board
  • AMB ceramic circuit board

DPC is direct plate copper technical.

DPC ceramic PCB stands for Direct Plated Copper ceramic Printed Circuit Board.
It is a type of printed circuit board that uses a ceramic substrate instead of a traditional fiberglass substrate (FR4).

The ceramic material offers better thermal conductivity and electrical insulation properties,making it ideal for high-power and high-frequency applications.

The DPC technology involves directly plating copper onto the ceramic substrate,
eliminating the need for a separate copper layer,
which reduces the board’s thickness and improves its thermal performance.

DPC ceramic PCBs are commonly used in power electronics, LED lighting, and aerospace applications.

DPC ceramic PCB advantage:


1. Min. conductor thickness: 10um (0.4mil )

The mean, You could design line width and space with very small
Min. Line width/Space :10um/10 um ( 0.4 / 0.4 mil )

2. More ceramic PCB substrate options

  • Alumina ( AL2O3 96% 99.6% )
  • Aluminum nitride (AIN ALN )
  • Silicon nitride ( SI3N4 )
  • Beryllium Oxide ( BeO )
  • Boron Nitride ( BN )
  • Silicon Carbide (SiC)
  • Zirconia ( ZrO2 )

Andwin could meet all of your DPC ceramic PCB substrate requirement,
You could choose suitable Ceramic PCB substrate for your electronic products.

DPC ceramic PCB Shortcoming:
Also,DPC ceramic PCB could meet your heavy copper upto 300um,
But the cost is very high.
Andwin provide you a economical suggestion – DBC ceramic PCB.


DBC is direct bond copper technique.

ceramic pcb

Copper foil bonded directly to alumina (AL2O3) or aluminum nitride (AIN,ALN) substrates one sided or double side at high temperatures.

Copper thickness: Min. 70um ( 2 OZ ) upto 300um
Ceramic material: alumina (AL2O3) or Aluminum nitride(AIN,ALN)

DBC Ceramic PCB advantage:

Meet thick copper requirement with comfortable cost,
Widely use IGBT and solar energy

DBC ceramic PCB Shortcoming:

Could not do plate through holes ( PTH )

Thick film ceramic printed circuit board is a type of ceramic PCB
That uses a thick film deposition process to create conductive traces and other circuit elements
on the ceramic substrate.

ceramic pcb resistor

The thick film deposition process involves printing a paste of conductive materials, such as silver, gold, or platinum, onto the surface of the ceramic PCB substrate.

And then firing it at high temperatures to create a permanent bond between the conductive material and the ceramic substrate.

This process is repeated to create multiple layers of conductive traces and insulating layers,resulting in a multi-layered ceramic PCB.

Thick film ceramic PCBs are commonly used in high-temperature and high-power applications,
Such as power electronics, automotive electronics, and aerospace industries,
Due to their excellent thermal conductivity and high mechanical strength.

Thick film ceramic PCB advantage:

1.It is lower cost ceramic PCB if use silver conductor
2.Via holes avaible for double sided ceramic circuit board.

Thick film ceramic PCB shortcoming:

Min.conductor width/Space : 0.15mm/0.15mm
During the thick film ceramic circuit board use silk printed technique,
Could not do very thin trace.

AMB is active metal brazing technology.

The AMB ceramic PCB is a type of printed circuit board that uses a ceramic PCB substrate instead of the traditional fiberglass or epoxy substrate.

AMB technology is a further development of DBC technology.
It is a method of combining ceramics and metals by using active metal elements (such as Ti/Ag/Zr/Cu) in solder.
Ceramics form a reactive layer that can be wetted by liquid solder.

The bonding in the AMB ceramic substrate is achieved by the chemical reaction of the ceramic and the active metal solder at temperature,

And the Si3N4 ceramic used in the AMB has a higher thermal conductivity (>90W/mK) Compared to the traditional Al2O3 ceramic substrate 25°C),

Which is closer to the thermal expansion coefficient of silicon (2.6×10 -6 /K).
Therefore, the AMB substrate has high adhesive strength and reliability.
Combined with silver sintering process and high-power silicon carbide chip,

AMB copper layer with active metal coating can realize high power,
Better heat dissipation and high reliability packaging module (can withstand 3000 thermal shocks),

Which has been widely used in Electric vehicles,electric motives and high-speed trains.

When the temperature increases, the thermal conductivity of zirconia will gradually increase,
And it can reach about 20 W/(m K) at high temperatures (about 1000 °C).

Insulation and conductivity
Zirconia ceramics do not conduct heat, do not conduct electricity at room temperature, and conduct electricity at around 1500°C

Zirconia ceramics have a negative temperature coefficient of resistance and are good electrical insulators at room temperature with a high resistivity.
But as the temperature rises, its resistivity drops sharply, and it has become a very good conductor at 1500 °C.
Zirconia ceramic PCB could use for special device such as laser device and space etc.

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