1.What Are Heavy Copper PCBs?

Heavy copper PCBs are also known as thick copper PCBs or power PCBs. They are unique due to their significantly thicker copper layers—typically ranging from 3 oz/ft² up to 20 oz/ft² or more. Standard PCBs typically have copper thicknesses of less than 2 oz/ft², so the enhanced current-carrying capacity of Heavy Copper PCBs makes them suitable for high-power applications.

2.Advantages of Heavy copper PCBs:

Improved Signal Integrity: High-frequency PCBs are designed to minimize signal loss and distortion, ensuring that data signals remain clear and accurate even at elevated frequencies. This is crucial for applications such as telecommunications and data transmission.
Lower Dielectric Loss: These PCBs utilize materials with low dielectric constants and loss tangents, which reduce energy loss during signal transmission. This enhances overall performance and efficiency, especially in high-speed and high-frequency environments.
High Thermal Stability: High-frequency materials can withstand elevated temperatures without degrading, making them suitable for demanding applications that generate significant heat. This property helps maintain the integrity and reliability of the PCB over time.
Precise Impedance Control: High-frequency PCBs enable precise control of impedance, which is critical for maintaining signal quality and minimizing reflections. This ensures optimal performance in RF and microwave applications.

Excellent EMC: High-frequency PCBs exhibit excellent electromagnetic compatibility (EMC) due to material characteristics that help minimize electromagnetic interference (EMI) and enhance signal integrity.

4.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.
