The Basics of Heavy Copper PCB

Heavy Copper PCB (Printed Circuit Board) refers to a type of PCB that uses thicker copper layers than conventional PCBs, typically greater than 3 ounces per square foot. The key advantage of using heavy copper is its ability to handle higher current levels and manage heat more effectively. This makes heavy copper PCBs an essential choice in applications where high power or heat dissipation is a concern.

In traditional PCBs, copper is used to form the traces that carry electrical signals. However, when higher currents are required, the increased resistance in these copper traces can lead to excessive heat generation. Heavy Copper PCB solves this issue by using thicker copper, which reduces resistance and allows the board to carry much higher current without overheating.

This type of PCB is widely used in high-power applications like power supplies, industrial machinery, automotive electronics, and more. It offers better thermal management, improving the durability and performance of the circuits. Heavy copper is especially important in scenarios that require consistent and reliable power delivery, as it helps to avoid thermal overloads and potential circuit failures.
