What is Heavy Copper PCB

Usually PCBs are manufactured using copper thicknesses ranging from 1oz to 3oz. Heavy copper PCB is also known as thick copper PCB, in which there are 3 ounces (oz) of copper or more on the internal and external layers of aprinted circuit board. The circuit board with a copper thickness of more than 4 oz per square foot (ft2) is also categorized as a heavy copper PCB.

Advantage of Heavy Copper PCB

Heavy copper PCBs come with numerous benefits over standard PCBs. 

Some PCBs are designed to carry higher current levels (amperage) by using wider traces. However, as power requirements increase, thicker copper is needed to transmit signals across the board.This is why heavy copper PCBs are used in high current designs.

The construction of a heavy copper circuit endows a board with benefits such as:

Improved thermal performance: Heavy copper PCBs can withstand repeated thermal cycles during manufacturing and assembly processes.

Increased current carrying capacity: Heavy copper PCBs offer better electrical conductivity and can handle higher current loads. Increasing the copper trace width can enhance the current carrying capacity, and thicker copper traces can handle even larger current loads.

Increased mechanical strength: Heavy copper PCBs enhance mechanical strength at connectors and plated-through holes, ensuring the board's structural integrity and making the electrical system more robust and resistant to voltage.

Excellent dissipation factor: Heavy copper PCBs are highly suitable for large power-loss components. These PCBs can prevent electrical systems from overheating and effectively dissipate heat.

Good conductor: Heavy copper PCBs are good conductors, making them useful in the production of electronic products. They help to connect various boards together, which can transmit currents.
