These PCBs are used for large (high) current output and optimized thermal management. Thicker copper allows larger PCB cross-sections to be used for high current loads and helps dissipate heat. The most common design is a multilayer or double-sided design. Using this PCB technology, the fine layout structure of the outer layer can also be combined with the thick copper layer of the inner layer.</p><p><br></p><p><br></p><p><strong>The performance of thick copper PCB:</strong></p><p><br></p><p>Thick copper PCB has the best elongation performance and is not limited by processing temperature. It can be used in hot-melt welding methods, such as blowing oxygen at a high melting point and not brittle at low temperatures. Even in an extremely corrosive atmosphere, copper PCBs will still form a strong, non-toxic passivation protective layer.</p><p><br></p><p><strong>Advantages of thick copper PCB:</strong></p><p><br></p><p><a href="https://www.atechpcb.com/pcb-manufacturing" rel="noopener noreferrer" target="_blank">Thick copper PCBs</a> are widely used in various household appliances, high-tech products, military, medical and other electronic equipment. The application of thicker copper PCB makes the core component of electronic equipment products-the circuit board has a longer service life, and is very helpful for reducing the size of electronic equipment.</p><p><br></p><p> </p><p><br></p><p>Among PCB prototypes, <a href="https://www.atechpcb.com/pcb-manufacturing" rel="noopener noreferrer" target="_blank">thick copper PCB</a> is a special technology, which has certain technical threshold and difficulty in operation, and is expensive. At present, in the PCB prototyping process, PCBWay can reach 2-6 layers (more than 6 layers, need to review), the maximum copper thickness is 10oz, and the minimum through hole is 0.4~0.6mm.</p>
