The primary advantage of ceramic multilayer PCBs lies in their thermal properties. The most significant of these is thermal conductivity, which outperforms traditional materials by a tremendous margin. In the table below, the most used board material, FR4, is compared with the ceramic multilayer board in a number of important categories.
MULTILAYER PCB MATERIAL COMPARISON
| Ceramic | Versus | FR4 |
| 28 – 280 | Thermal Conductivity (Wm-K) | 0.8 – 1.1 |
| Component Comparable | Coefficient of Thermal Expansion (CTE) | Component Comparable |
| High | Frequency Performance | Low – Mid |
| Fragile | Handling | Easy |
| Low | Availability | High |
| Mid – High | Cost | Low – Mid |
As shown above, ceramic multilayer PCBs have advantages and disadvantages as compared to FR4. However, the advantages point to a continued increase in the use of ceramic boards for high-speed and high-power applications that are criteria for more functionality in smaller packages.
