How to Calculate Current Capacity for Heavy Copper PCB

Specifying heavy copper—boards with 4 oz/ft² or thicker layers—is rarely done for light-duty applications. It is a decision driven by a specific thermal management challenge: moving massive current through a limited space without compromising the board's integrity. Whether building EV motor controllers or renewable energy inverters, the physics remains the same. Here is the catch: Standard online PCB calculators often fail to capture the reality of heavy copper. Most designers instinctively grab a free calculator or a generic IPC chart, plug in the current, and size the trace. While effectiv ...

You’ve likely seen this on the bench or in the field. A high-power LED build looks solid during testing but fails prematurely in the real world. The weak link usually isn't the driver or the chip; it’s the board itself. Standard FR4 boards act like thermal blankets, trapping heat exactly where it destroys the junction. If you’re pushing real power—anything beyond a simple indicator—an aluminum PCB isn't a luxury upgrade. It is an engineering necessity to protect your investment from the inevitable thermal load. <img src="https://images.theengineeringprojects.com/imag ...
