What is a Heavy Copper PCB and Where is it Used

You use a heavy copper pcb when you need extra durability and power.

The PCB industry considers 3 or more ounces of copper on any circuit board layer as heavy copper.
Standard boards usually have less copper. Heavy copper pcb options handle more current and heat than standard types.

You find heavy copper pcb manufacturers​ in industries that need strong and reliable circuit boards.

Key Takeaways

• Heavy copper PCBs have at least 3 ounces of copper per square foot, providing increased strength and current capacity for demanding applications.

• These PCBs excel in thermal management, effectively spreading heat to prevent overheating and ensuring reliable performance in high-power environments.

• LT CIRCUIT offers high-quality heavy copper PCBs tailored for industries like automotive and aerospace, ensuring durability and customization for specific needs.

Heavy Copper PCB Features

Copper Thickness

You can identify a heavy copper PCB by its copper thickness. Standard PCBs usually have 1 ounce of copper per square foot. Heavy copper PCBs start at 3 ounces per square foot, which equals about 105 micrometers (µm). Some designs use up to 20 ounces per square foot, exceeding 200 µm.

This extra thickness matters. It gives your board more strength and better performance.

The importance of copper thickness in PCB manufacturing cannot be ignored because it directly affects the conductive performance, heat dissipation performance, mechanical strength and signal integrity of the circuit board.

When you choose a heavy copper PCB, you get a board that can handle more current and heat. This makes it ideal for demanding applications.

Performance Benefits

Heavy copper PCBs offer several key advantages. You will notice these benefits most in high-power or industrial settings.

You will see improved current carrying capacity, which means your board can safely deliver more power. Superior thermal management helps your devices stay cool. Thicker copper layers spread heat more effectively, reducing the risk of hot spots that can damage components.

Increased copper thickness in a PCB enhances its mechanical strength and reliability, making it less prone to warping or bending, which is particularly important for applications subjected to mechanical stress or environments with vibration or impact.

You also get better reliability. Heavy copper PCBs last longer and resist wear and tear.

Thicker copper layers provide better resistance to wear and tear, improving the overall lifespan and reliability of the PCB.

Standard vs Heavy Copper

You might wonder how heavy copper PCBs compare to standard boards. The differences are clear when you look at electrical performance and durability.

Standard PCBs work well for low-power devices. Heavy copper PCBs excel in high-power and high-stress environments. You get higher current-carrying capacity and much better thermal management. This means your board can handle more demanding tasks without overheating or failing.

Heavy copper PCBs also give you more design flexibility. You can create complex circuits that need both power and control signals on the same board.

Heavy copper PCBs have thicker copper layers, which enhance thermal conductivity. This increased thickness allows for more effective heat spreading and release. The design reduces the risk of hot spots that can damage electronic components.
