Why Use Heavy Copper PCB?

Copper is a material with high electrical conductivity (58.5 MS/m) and low resistance (1.68 μΩ·cm).

Standard PCBs often fail under high-stress conditions. Engineers choose Heavy Copper primarily to bridge the gap between complex circuitry and extreme power demands.

Advantages of Heavy Copper PCB

Enhanced Reliability of Electronic Components

• High Thermal and Electrical Conductivity: Heavy Copper PCBs offer excellent thermal and electrical conductivity, effectively dissipating and conducting heat to prevent component burnout due to heat concentration.
• Applications: Suitable for power management systems, high-power LEDs, industrial control systems, and automotive electronics where high reliability is required.

Corrosion Resistance

• Protective Layer: Heavy Copper PCBs can form a thin layer of copper oxide in the air, providing additional corrosion protection and extending the PCB’s service life.
• Applications: Ideal for devices exposed to harsh environments, such as outdoor electrical equipment, marine equipment, and chemical equipment.

High Temperature Resistance and Thermal Stability

• Stability: Heavy Copper PCBs maintain their physical and chemical properties in high-temperature environments and are not prone to decomposition or damage.
• Applications: Suitable for applications in high-temperature environments, such as aerospace equipment, electric vehicle battery management systems, and high-power amplifiers.

Efficient Signal Transmission

• Low Resistivity: Using Heavy Copper as the conductive layer provides low resistivity and excellent conductivity, enabling high-speed signal transmission and reducing signal loss.
• Applications: Suitable for high-speed communication equipment, server motherboards, and high-frequency RF applications.

Electromagnetic Shielding

• Superior Shielding Performance: Heavy Copper PCBs have excellent electromagnetic shielding capabilities. Their high conductivity allows them to effectively reflect and absorb electromagnetic waves, reducing electromagnetic interference (EMI).
• Applications: Ideal for devices sensitive to electromagnetic interference, such as medical equipment, communication devices, and precision measurement instruments.

Machinability and High Mechanical Strength

• Ease of Processing: Heavy Copper has good ductility and flexibility, making it easy to process into various shapes and sizes.
• High Mechanical Strength: Heavy Copper PCBs provide sufficient mechanical strength, offering good physical protection and preventing damage during operation and use.
• Applications: Suitable for applications requiring high mechanical strength and complex structures, such as military equipment, heavy machinery, and large industrial equipment.
