I want to use some PCB etch board to make a plate that gets a little warm ... maybe 35C at the most.
But, I'm unclear as to the best way to go about this in terms of the layout of the copper.
Would it be better to leave the etch board un etched and just connect the leads on each side like this?
Or would it be better to etch it so that there is a longer path of copper for the charge to follow, like this?
