Can a PCB board be made so that you can solder on the track a thicker layer that can handle more Amps? See attached “motor controller”
I have to solder thick wire on the big track (red)…is that possible? and if so how do I tell the manufacturer this?
I use Kicad
With best regards

Hi 
What amount of current do you run through that trace and at which frequencies?

Approx. 40 Amp and 400 hz
5 years ago I made the motor controller on ExpressPCB and it still works. a thick layer of tin is soldered on the tracks to the Mosfet.
Now I have drawn it in Kicad and am asking if you can expose the top layer of Cu so that I can solder a thick layer onto the track.
Best regard

You can create a soldermask opening in KiCad using the F.Mask layer for the top side and B.Mask for the bottom side.
