High current-carrying printed circuit board and method for producing said printed circuit board
A printed circuit board includes a busbar applied to a surface of the printed circuit board. The busbar is configured as a sequence of sheet metal conductor pieces which are connected to each other in an electrically conducting manner. The respective ends of the conductor pieces may have a rounded portion and a corresponding cutout, or a point and a corresponding indentation. An electrical controller, a motor vehicle and a printed circuit board configuration having at least one printed circuit board are also provided.

all of said multiple, identical electrically conductively interconnected sheet metal conductor pieces being mounted directly to said surface of the printed circuit board in a single plane.
2. The printed circuit board according to claim 1 , wherein said at least one end includes at least one angular portion.
3. The printed circuit board according to claim 1 , wherein said at least one end includes a rounded portion.
4. The printed circuit board according to claim 1 , wherein said sheet metal conductor pieces have a rounded portion at one of said ends, and a cutout corresponding to said rounded portion at the other of said ends.
5. The printed circuit board according to claim 1 , wherein said sheet metal conductor pieces have an indentation at one of said ends, and a point corresponding to said indentation at the other of said ends.
6. The printed circuit board according to claim 1 , wherein said surface of the printed circuit board is populated with said sheet metal conductor pieces for surface-mountable devices.
7. The printed circuit board according to claim 1 , wherein said sheet metal conductor pieces are mechanically and electrically conductively connected to at least one of other sheet metal conductor pieces or conductor tracks of the printed circuit board by at least one of reflow solder or an adhesive bond using an electrically conductive adhesive.
8. The printed circuit board according to claim 1 , wherein said busbar is configured to be used in an electrical controller, a heavy-current electronic unit, an on-board power supply system controller, a fuse box, a hybrid electric vehicle or a non-automotive high-current application.
