What is heavy copper PCB?
This PCB classic is the first choice when high currents are unavoidable: the thick copper PCB, manufactured in genuine etching technology. Thick copper PCBs are characterised by structures with copper thicknesses from 105 to 400 µm. These PCBs are used for large (high) current outputs and for optimisation of the thermal management. The thick copper allows large PCB-cross-sections for high current loads and encourages heat dissipation. The most common designs are multilayer or double-sided.
