What types of circuits can be used with ceramic PCBs?
There are several types of circuits which can be used with ceramic PCBs. The following are some examples.
High-speed circuits
RF circuits
Heat dissipation circuits
Power supply circuits
Temperature compensation circuits
Are ceramic PCBs more expensive than traditional FR-4 boards?
Yes, ceramic PCBs are more expensive than traditional FR-4 boards since the ceramic substrate is a new and superior-performance of PCB material.
How are ceramic PCBs manufactured?
The following is a simplified manufacturing process for ceramic PCBs.
Prepare the raw material → inner layer copper trace etching → laminating → drilling → out layer copper trace → solder mask printing → surface treatment → silkscreen printing → open/short testing → final quality inspection → packaging.

What are the main difference: Ceramic pcb vs FR4?
1. The substrates are different;
2. The usages are different;
3. Costs are different: the copper-clad ceramic substrate is much more expensive;
4, Different in production: the ceramic PCB manufacturing process is more difficult.
Are there any special considerations to keep in mind when designing a ceramic PCB?
When designing ceramic PCBs, we must not take the design lightly and should keep several considerations in mind.
When designing a ceramic PCB, we should carefully select the dielectric material for the desired application.
Controlled impedance are always needed in ceramic PCBs, so designers should calculate the impedance value according to the material parameters (Er), copper thickness, copper width/space, dielectric thickness, etc.
Since ceramic material is much more expensive than FR4 material, a ceramic circuit board design should consider the PCB cost and the overall application price.
If we identify potential problems early in the design process, we can ensure success in later stages. With careful planning, ceramic PCBs can provide excellent solutions for various applications. Please get in touch with us freely if you have any questions regarding ceramic PCBs.
What is the lead time for ceramic PCB manufacturing?
Our standard lead time for PCB production is around 1-3 weeks. But sometimes, we may need a few weeks to buy special ceramic material. So, conditions like material type and technology used on the PCB will determine the exact lead time for ceramic PCB manufacturing.
What is the cost of a ceramic PCB?
The following factors determine the ceramic PCB cost.
Substrate material (most critical part);
Quantity per batch;
Process Technology, such as blind/buried vias;
Difficulty in manufacturing, such as very tight impedance tolerance, tight copper width tolerance;
Other special requirements.
What the the difference between Ceramic PCB and Teflon PCB?
The materials are different:
Teflon is a kind of polyimide material, which is a special kind of high-performance plastic. But ceramic is a kind of compound made of boron nitride, beryllium oxide and silicon carbide.
Usages are different:
Teflon PCBs are always used for microwave and RF applications. But ceramic materials are usually reinforced with a combination of other materials, so ceramic substrates are more widely used.
PCB production process and techniques are different:
This is because the characteristics of the two kinds of materials are totally different.
