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. 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.
Performance of Thick Copper PCB:
Thick copper PCB has the best elongation performance and is not limited by the processing temperature. It can be used in hot melt welding methods such as oxygen blowing at high melting point and not brittle at low temperature. Even in extremely corrosive atmospheric environments, copper PCB forms a strong, non-toxic passivation protective layer.
Advantages of Thick Copper PCB:
Thick copper PCB is widely used in various household appliances, high-tech products, military, medical and other electronic equipment. The application of thick copper PCB 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
In PCB prototype, thick copper PCB belongs to a special technology, has certain technical thresholds and operating difficulties, and is relatively expensive. At present, in the process of PCB prototype, PCBWay can achieve 2-6 layers (more than 6 layers, need to be reviewed), the maximum copper thickness is 10oz, the minimum via hole is 0.4 ~ 0.6mm.
