Estimate minimum PCB trace width for a given current, copper thickness, and temperature rise.
Higher current requires wider traces to prevent overheating and voltage drop.
Standard PCB copper weights: 0.5 oz, 1 oz, 2 oz. Thicker copper carries more current.
Typical allowable temperature rise: 10-20°C for general purpose, 5°C for sensitive circuits.
Longer traces increase resistance and voltage drop. Consider increasing width for long traces.
IPC-2221 provides guidelines for trace sizing based on current, temperature, and copper weight.
