The other parameters required by this tool are trace thickness (Th), ambient temperature (Ta), and trace length (L). Insufficient trace width may lead to trace burn, impacting the PCB functionality. Hence, we need to know how much trace width is enough to carry that high current. Trace width calculation is critical for high-current PCBs. This is the only tool that gives you this advantage. You can alter any two of these parameters to find the third one. Maximum current (Imax) – if the temperature and the trace width values are given.Temperature rise (ΔT) – if the trace width and maximum current values are given. ![]() Trace width (W) – if the maximum current and the temperature rise above the ambient are given.
