custom 2-Layer Heavy Copper PCB Manufacturing for High Current & Power Applications

Copper Based PCB Manufacturer | One-Stop PCB & PCBA Solutions by Ring PCB

What Is a 2-Layer Heavy Copper PCB?

A 2-layer heavy copper PCB is a specialized printed circuit board designed to carry extremely high current while maintaining electrical stability and thermal reliability. Compared with standard copper PCBs, heavy copper PCB manufacturing uses significantly thicker copper layers—typically ranging from 3 oz up to 20 oz or more—to support high-current transmission and enhanced heat dissipation.

The heavy copper PCB shown in the image is a customized solution manufactured for a customer’s high-power application, presented for reference to demonstrate Ring PCB’s heavy copper PCB manufacturing capabilities.

This type of PCB is widely used in power electronics, industrial control systems, power distribution units, motor drives, energy storage systems, and high-current equipment.

Key Features and Advantages of Copper Based PCB

1. Excellent Heat Dissipation

Copper has outstanding thermal conductivity, allowing fast heat transfer from critical components. This significantly improves product stability and lifespan.

2. High Mechanical Strength

A Copper based PCB provides better mechanical rigidity and durability, suitable for harsh environments and industrial-grade applications.

3. High Current Carrying Capacity

Thanks to thick copper layers and a solid metal core, Copper based PCB designs can handle high current loads with minimal power loss.

4. Superior Reliability

Reduced thermal stress and improved heat distribution help minimize failure rates, especially in high-power LED, automotive, and power electronics.

5. Customizable Structure

Ring PCB supports full customization of Copper based PCB stack-ups, copper thickness, surface finish, and overall design to meet specific industry needs.
