# Ceramic Multilayer PCBs: Advantages and Disadvantages

_Published: 2020-01-06_

The primary advantage of [ceramic multilayer PCBs](https://www.bestpcbs.com/products/ceramic-pcb.htm) 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](https://www.bestpcbs.com/products/ceramic-pcb.htm) in a number of important categories.
