Ceramic substrates are made from technical ceramics, mainly alumina (Al2O3), aluminum nitride (AlN), silicon nitride (Si3N4), beryllium oxide (BeO), and silicon carbide (SiC). They are primarily used for installing electronic components, interconnecting them, and heat dissipation.
The core features of ceramic substrates cover high thermal conductivity, low coefficient of thermal expansion (CTE), high mechanical strength, resistance to high temperature, high frequency, and chemical stability in various harsh working conditions.
Ceramic substrates offer 10x higher thermal conductivity than aluminum PCBs, with superior electrical insulation and miniaturization potential.
When you need to choose a ceramic substrate, you need to focus on the following aspects:
- Types of ceramic material: Different types have considerable differences in properties and extreme cost differences.
- The properties: It’s crucial to learn the properties of ceramic substrates in different ceramic materials. Exceedingly physical, thermal, electrical, and optical properties.It will help you to make a productive and utterly right decision.
- Whether the relevant ceramic substrate can fully match the actual applications.
- Cost-effectiveness in mass production: It’s essential to evaluate the cost-effectiveness of ceramic substrates, especially high-volume production because they have extreme cost differences for different types of ceramic materials.
1. The difference on attributes:
Ceramic substrates have better thermal conductivity, lower thermal expansivity, more stable dielectric constant, higher temperature resistance, and better chemical inertness than FR4.
However, frangibility is the biggest weakness of ceramic substrates. It needs to pay special attention to the installation process.
2. The difference on sizes:
Thanks to the manufacturing and equipment limits, Making very large-sized ceramic substrates isn’t easy, but it’s not a question to achieve for FR4.
3. The difference on cost:
In most cases, the cost of ceramic substrates is higher than that of FR4 because of more costly raw materials and complicated fabrication processes of ceramic substrates.
Sometimes, a combination of ceramic substrates and FR4 is suggested, such as FR4 being the primary substrate and some specific sections using advanced ceramic substrates.
4. The difference on applications:
If you are looking for substrates for high-power LED, RF & microwave modules, electronics, high-temperature sensors, and aerospace applications, technical ceramic substrates will be recommended.
On the contrary, FR4 will be recommended if the substrate is used in consumer electronics, common power boards, low-frequency digital circuits, and low-cost IoT devices.
5. Other differences:
Due to expensive post-processing costs and circuit design limits of ceramic substrates, it’s easier to achieve complex circuits on FR4, but it’s more difficult on ceramic ones.
