You can use high currents on a PC board with a very wide trace.  I've
got a slide chart at my bench that says you need a .950 inch wide
trace to handle 20 amps on a 1 ounce copper board, half that with two
ounce copper.

AMP makes several good terminals that will solder onto boards.  I
would recommend you rivet the connector on the board for these kinds
of currents.   I've got a project on the drawing board now
using an AMP part number 61407-3 that can be soldered and riveted to
a board.

P.S.  I apologize for giving you measurements in inches - metric is
not my native language either.
