Heavy Copper PCB
What is Heavy Copper PCB? Heavy Copper PCB is a printed circuit board (PCB) with a layer of copper foil bonded to its glass epoxy substrate. When the thickness of the copper foil is greater than or equal to 2 ounces (i.e. ≥2oz), it is called Heavy Copper PCB.
Copper performs the function of conducting electricity on the circuit board. Heavy Copper PCB has the characteristics of carrying large current, reducing thermal strain, and having good heat dissipation.
The application scenarios of Heavy Copper PCB are very wide. Here are some common application scenarios:

SMT Capacity
Thick copper PCB is a special type of printed circuit board that has a thicker copper layer compared to a standard PCB. This increased copper thickness provides several advantages and is suitable for specific applications.
Key features of thick copper PCB include:
Copper thickness:
A standard PCB’s copper layer thickness is typically 1 to 2 ounces per square foot (oz/ft²), which equates to a thickness of approximately 35-70 microns.
Thick copper PCBs have significantly thicker copper layers, typically 3 oz/sq ft to 12 oz/sq ft or more, which equates to a thickness of 105-420 microns.
Power handling capability:
Increased copper thickness enables thick copper PCBs to handle higher current and power levels without excessive heat build-up or voltage drops.
This makes them ideal for power-intensive applications such as power supplies, motor drives and high-current electronic systems.
Thermal management:
Thicker copper layers act as effective heat sinks, improving heat dissipation from heating components on the PCB.
This enhanced thermal management capability is critical for high-power, high-current, or high-density circuit designs.
Electrical conductivity
The increased copper thickness reduces the trace's resistance, improving overall circuit performance and signal integrity.
This is beneficial for applications requiring low impedance, high current circuits such as power electronics or high-speed digital designs.
Stiffness and Mechanical Strength:
Due to the increased copper thickness, thick copper PCBs tend to be stronger and mechanically stronger, making them suitable for applications with vibration, shock or stress requirements.
Manufacturing Challenge:
Making thick copper PCBs requires specialized manufacturing processes such as advanced drilling techniques, enhanced plating, and specialized etching methods.
These manufacturing processes can be more complex and costly compared to standard PCB production.
Applications of thick copper PCB include:
Power electronics, such as inverters, converters and motor drives
High current circuits, including industrial control and distribution systems
Automotive electronics including electric vehicles and hybrid powertrains
Aerospace and defense applications with strict power and thermal requirements
Telecommunications and networking equipment with high current and power requirements
Thick copper PCBs can be used in the design and development of rugged, reliable and high-performance electronic systems in a variety of industries where power handling, thermal management and electrical conductivity are key factors.
