Product Description:
A heavy copper PCB (Printed Circuit Board) is a type of circuit board that has significantly thicker copper thickness compared to standard PCBs.
This enhanced copper thickness is specifically designed to handle high-current applications and provide superior thermal management.
Key Characteristics and Definition
Copper Thickness: Standard PCBs typically have a copper thickness ranging from 0.5 to 3 ounces per square foot (oz/ft²), the heavy copper PCB is defined as having a copper thickness of 3 oz/ft² or more on its inner and/or outer layers. In some cases, "extreme heavy copper" PCBs can have copper weights exceeding 20oz/ft².
Measurement: The copper weight is measured in ounces per square foot (oz/ft2), which represents the weight of copper that would cover one square foot of the board. A higher ounce value corresponds to a thicker copper layer.
Trace Characteristics: The thicker copper layers allow for wider and taller traces, which reduces the electrical resistance. This is crucial for applications that require carrying high currents without generating excessive heat.
