1. A method for producing a circuit carrier arrangement, comprising the steps of:
providing a cooling plate (1) which has spacer and fastening elements (3) for connection to a printed circuit board (2) in a spaced-apart manner; a printed circuit board (2) which has bores (4) for receiving spring element sleeves (9), at least one power semiconductor component (10) having plug-in connections (11) of spring-action configuration; and at least one spring element (5) which is formed with at least two spring element sleeves (9) between which a web (6) that is connected to the spring element sleeves (9) extends, and supporting elements (7) that extend perpendicularly in relation to the longitudinal direction of the spring element sleeves (9) being arranged on either side of said web and at least one spring plate (8) being arranged on said web,
fitting a spring element (5) on the printed circuit board (2) by inserting its spring element sleeves (9) into the bores (4) in the printed circuit board (2),
fitting the at least one power semiconductor component (10) on the printed circuit board (2) by inserting its plug-in connections (11) into the bores (4), provided for them, in the printed circuit board (2) and soldering the plug-in connections (11) to conductor tracks on the printed circuit board (2), wherein the at least one spring plate (8) is positioned between the printed circuit board (2) and an associated power semiconductor component (10),
connecting the printed circuit board (2) and the cooling plate (1), so that they are spaced apart from one another by the spacer and fastening elements (3), and the at least one power semiconductor component (10) and the associated spring plate (8) are positioned between the printed circuit board (2) and the cooling plate (1), and
clamping the at least one spring plate (8) and as a result pressing the at least one power semiconductor component (10) against the cooling plate (1) by screwing in screws (13) that are inserted in the spring element sleeves (9).
