Once I had to design a board with 20A Current carrying conductors. At that time no info was given about temperature.
I took 2oz Copper and 200 mil track width. (Calculated from some application note)

Dear Treez,
I purchase Stencils from Hong Kong.
PCB Size is 6UB.
Use for following Essemtec Manual Printer
