Is there a standard/calculator available to calculate trace width for designing metal clad PCBs? Many calculators available online can only calculate trace width for FR4 PCBs based on the IPC standard. I understand that due to better thermal performance of metal clad PCB, the temperature rise of the trace will be less compared to FR4 PCB for the same amount of current, thus providing more current capacity. But is there a standard or a correlation (maybe a formula) available, with which we can translate the trace width values for FR4 PCB to metal clad PCB?
