Can someone tell me how much current a 1mm wide trace on a PCB can handle?
Thanks

Not certain about 1mm wide trace but maybe these will help.

Google search : pcb+current+capacity leads to:

have you considered the depth? then is the quality of of the board itself. it is a valid question but inpossible to answer .

There are various online calculators, just use Google imaginatively. There is
no fixed figure, it depends on the temperature you you can accept.
