Product Detail

Main Ceramic PCB Types

From the level of substrates, ceramic PCBs include the aluminum, AIN, BeO, Si₃N₄, hybrid substrate boards, etc. From the layers of the circuit boards, there are the single-layer, double-layer, and multilayer.

Ceramic PCBs are usually made up of ceramic cores, with alumina and aluminum nitride (AIN) being two of the primary types. Both of these kinds of boards provide better thermal performance than metal core PCBs because there isn’t a need for an electric layer between the core and the circuits. Find out more about these two main kinds of ceramic PCB types below:

AIN (Aluminum Nitride)

For high thermal conductivity, aluminum nitride boards are ideal, providing greater than 150 w/mK. AIN is a top choice for many other reasons as well, such as its good dielectric properties, non-reactiveness with various semiconductor process chemicals and low CTE.

Alumina (Aluminum Oxide)

Since aluminum nitride boards are expensive, those opting for less expensive ceramic PCBs may find themselves with Alumina boards. These PCBs are made out of aluminum oxide and offer about 18-36 w/mK.

Frequently Asked Questions

What are the main types of ceramic PCB substrates?

Ceramic PCBs are categorized by substrate materials, including alumina (aluminum oxide), AIN (aluminum nitride), BeO, Si₃N₄, and hybrid substrates. They can also be classified by layer count into single-layer, double-layer, and multilayer boards.

Why do ceramic PCBs offer better thermal performance than MCPCBs?

Ceramic PCBs deliver superior thermal performance because they do not require an electrical insulation layer between the core and the circuit layers, which is typically a thermal bottleneck in standard metal core PCBs (MCPCBs).

What makes AIN ceramic PCBs suitable for high-power applications?

AIN (Aluminum Nitride) boards provide exceptionally high thermal conductivity of greater than 150 w/mK. They also feature excellent dielectric properties, a low coefficient of thermal expansion (CTE), and high chemical resistance.

When should I choose Alumina over Aluminum Nitride (AIN)?

Alumina (aluminum oxide) is a cost-effective alternative to AIN. While it offers a lower thermal conductivity of 18-36 w/mK, it is ideal for projects requiring the benefits of a ceramic substrate on a more limited budget.

What layers are available for ceramic circuit boards?

Depending on the complexity of the circuit design, ceramic PCBs can be manufactured in single-layer, double-layer, and multilayer configurations to meet various high-performance requirements.
