What is heavy copper PCBs?

Most heavy copper PCBs are made of FR4 material, but can also be made by polyimide which is called heavy copper flex PCB.The PCB copper thickness in normal PCB is around 0.5 to 2 ounces, which is 17.5 to 70um. Some printed circuit boards need thicker copper thickness than 2 ounces (70um). When the finished thickness of copper foil on the copper layer is more than 2 ounces (70um), we call it heavy copper PCB, also extreme copper PCB.

Applications

Due to their unique properties, heavy Copper PCB are widely used in a variety of fields.

The following are their main applications:

• 1. Power Supplies: Power supplies are essential components of electronic devices, requiring them to withstand high currents and power. Heavy Copper PCBs' high conductivity and load-carrying capacity make them an ideal choice for power supplies.

• 2. Industrial Control Equipment: Industrial control equipment often requires the control and monitoring of numerous sensors and actuators. Heavy Copper PCBs provide stable and reliable circuit connections, ensuring the proper functioning of these devices.

• 3. New Energy Vehicles: Key components in new energy vehicles, such as motor controllers and battery management systems, must withstand high current and power loads. The high performance of Heavy Copper PCBs meets these stringent requirements.
