This coating can quickly move heat away from hot regions and dissipate it throughout the entire surface.Ĭeramic offers a significant advantage over more traditional materials like FR-4 and metal-clad PCB in terms of heat dissipation. The PCB’s basis is ceramic and extremely thermally conductive elements such alumina, aluminum nitride, and beryllium oxide (which are frequently coated with immersion gold). If that isn’t enough, there’s also a ceramic PCB to consider. Aluminum PCBs are generally used in making LED light panels. The aluminum absorbs heat much faster than FR-4 material, it protects PCB components from overheating, and it extends their lifespan. If the produced heat is too much, we generally use metal-clad PCBs where an electrically insulated aluminum sheet is used as the PCB base. This technique only works up to a certain extent, though.

The FR-4 material is not an excellent conductor of heat, but the copper pour helps the circuit cool down. A prevalent way to dissipate heat from a circuit is by adding a copper surface layer to the circuit’s unused part. For standard circuits, the amount of heat is not enough to harm the whole circuit. There are several reasons behind this heat generation. TemperatureĪs you already know, any electronic device dissipates some amount of heat while functioning.
