Product Description
What Is a Copper Based PCB?
A Copper based PCB is a type of metal core printed circuit board that uses copper as the base material instead of traditional FR-4. Due to copper’s excellent thermal conductivity, this PCB structure is widely used in applications requiring efficient heat dissipation, high power density, and long-term reliability. A Copper based PCB typically consists of a copper base layer, a high-performance dielectric layer, and a copper circuit layer.
Compared with aluminum or standard FR-4 boards, Copper based PCB solutions offer superior thermal management, making them ideal for high-power and high-frequency electronic applications.

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.
The Manufacturing Challenges for Heavy Copper PCBs at Ring PCB
1. Etching Process
Challenge: Standard PCB etching techniques struggle with thick copper layers. As copper thickness increases, the etching process becomes more difficult, requiring precise control to avoid uneven or incomplete etching.
Solution: Advanced etching processes are employed to handle thicker copper, using controlled chemical etching and temperature management to achieve uniform copper traces. In some cases, multiple etching steps are used to gradually achieve the desired thickness.
2. Thermal Management During Manufacturing
Challenge: Thick copper layers retain heat, which can lead to issues with warping, delamination, or internal stress during high-temperature processes like lamination and soldering.
Solution: Temperature control and gradual thermal cycling are applied throughout manufacturing. Special solder masks that can endure higher temperatures are also used to prevent damage during soldering and reflow.
3.Drilling and Hole Quality
Challenge: Heavy Copper PCBs are more difficult to drill accurately due to their dense copper layers, which can cause bit wear, misalignment, and burrs around drilled holes.
Solution: Ring PCB reduces lifespan of drill bits and replace them sooner. Additionally, using high-precision drilling machines and specialized drill bits designed for thick copper can be beneficial. Furthermore, segmenting the drilling process can help minimize drill bit wear.
4.Copper Plating
Challenge: Plating thick copper requires copper plating layer can adhere to the original copper layer, enhancing the overall bonding strength.
Solution: PCBs are typically subjected to cleaning to remove contaminants, followed by both chemical and mechanical roughening to create a microscopically rough surface on the copper. A final copper plating step ensures uniform coverage.
5.Hole Size Compensation
Challenge: After the copper plating in Heavy Copper PCB manufacturing, the hole size can become smaller. This is because the plating process deposits additional copper within the drilled holes, increasing the thickness of the copper on the hole walls and slightly reducing the diameter.
Solution: Ring PCB carefully calculates the initial drill size based on the thickness of copper that will be added in the plating process. The hole is drilled slightly larger than the final required size to allow for the subsequent plating buildup.
5.Applications of Heavy Copper PCBs
Heavy Copper PCBs are indispensable in applications where high current and enhanced thermal performance are essential. Some common applications include:
Automotive Electronics: Used in electric vehicles, power converters, and braking systems due to their high current handling.
Aerospace and Military Equipment: Essential for equipment where reliability and durability in extreme environments are required.
Power Supplies: Heavy Copper PCBs are ideal for uninterruptible power supplies (UPS) and other high-power devices that require stable power management.
Renewable Energy: Found in wind turbines and solar power systems, where high current capacity and durability are needed for efficient energy conversion.
Industrial Equipment: Used in heavy-duty machinery, motor controls, and power distribution units for efficient heat management and reliability.
Ring PCB supports 3-day rapid prototyping and 7-day mass production, depending on design complexity and order quantity.
