Abstract:
The present invention relates to a printed circuit board arrangement (400) and a method for forming an electrical connection at a printed circuit board. The printed circuit board arrangement comprises a printed circuit board (410) having a first side (411), a second side (412) and an electrical connection (413) electrically connecting a first conductive layer and a second conductive layer (417) of the printed circuit board. The electrical connection (413) comprises a passage (416) extending from an opening in one of the sides of the printed circuit board through the printed circuit board between the first and second layers. Electrically conducting material (414) is formed on the walls (415) of the passage. The electrically conducting material forms a first path electrically connecting the first conductive layer (417) with the second conductive layer (417). At least one first ball 420 is enclosed by the passage. The at least one firstball is electrically conducting and has a diameter which is equal to or smaller than the length and diameter of the passage, wherein the at least one first ball (420) form part of a second electrical path between the first and second conductive layers of the printed circuit board, said second electrical path having a lower resistance than the first path.
