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.

Wave soldering is a widely used mass soldering process in the manufacturing of electronics, especially for through-hole elements and intricate technology printed circuit boards. In this method, a PCB is ignored, and a wave of melted solder permits solder joints to form on vulnerable part leads and pads at the same time. While wave soldering is effective and cost-efficient for high-volume manufacture, it is also liable to certain flaws if the method parameters, textiles, or patterns deliberation are not handled carefully.
Wave soldering defects in PCB assembly refer to general soldering flaws, ...
