Thick copper PCBs are characterized by structures with copper thicknesses from 105 to 400 µm. These copper PCB boards are used for large (high) current outputs and optimization of thermal management. The thick copper allows large PCB-cross-sections for high current loads and encourages heat dissipation. The most common thick copper PCB board designs are multi-layer or double-sided. With this PCB technology it is also possible to combine fine layout structures on the outer layers and thick copper layers in the inner layers.
Advantages of it:
Thick copper PCB board is widely used in various household appliances, high-tech products, military, medical and other electronic equipment. The application of thick copper PCB board makes the core component of electronic equipment products-circuit boards have a longer service life, and at the same time it is very helpful to the size reduction of electronic equipment.
