The defining feature of a High Current Pcb is its use of Heavy Copper, typically ranging from 2oz to 6oz or more. These wider and thicker copper traces drastically reduce electrical resistance and minimize power loss. This robust structure not only enhances the board's current-carrying capacity but also significantly improves Thermal Management by dissipating heat more efficiently to prevent overheating.
Widely used in Automotive Electronics, Industrial Power Supplies, and renewable energy systems, High Current PCBs are essential for ensuring the reliability, durability, and safety of modern high-power electronic devices.
