Abstract: The present invention relates to a printed circuit board arrangement and a method for forming an electrical connection at a printed circuit board. The printed circuit board arrangement comprises a printed circuit board having an electrical connection electrically connecting a first conductive layer on a first side of the printed circuit board and a second conductive layer on a second side of the printed circuit board. The electrical connection comprises a passage 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 is formed on the walls of the passage and forms a first path electrically connecting the first conductive layer with the second conductive layer.

Abstract: An object of the present invention is to provide an improved and simplified filter assembly. The object is achieved by a dielectric rod (120, 610, 620) for a filter chassis (110). The dielectric rod (120, 610, 620) extends between a first end (121) and a second end (122). The dielectric rod (120, 610, 620) comprises a conductive element (150) placed at the first (end 121). The conductive element (150) is adapted to be in conductive contact with a first contact means (141) of the filter chassis (110). The dielectric rod further comprises a second fastening element (160) placed at the second end (122). The second fastening element (160) is adapted to be attached and detached to a first fastening element (131) comprised in the filter chassis (110), such that the dielectric rod (120, 610, 620) is replaceable in the filter chassis (110).
