    Hey just wondering if I want to etch my own PCB and it will be used with a 24V 1-2A current. What is the thickness and width I'd need to have for the traces? I calculated it as .31mm width at 1oz trace thickness but want to make sure

    What is the length of your trace?

    Use 40thou and if it gets hot, solder tinned copper wire to the top.
