Abstract:
1. An arrangement comprising: a printed circuit board having strip conductors; a power semiconductor module including a module housing and power terminals which extend to the exterior of the module housing and into contact with the strip conductors; a heat sink disposed on a side of the power semiconductor module opposite the printed circuit board; elastically or plastically deformable means being disposed between the module housing and the printed circuit board and being in contact with the module housing and the printed circuit board, the deformable means being configured to relieve a contact pressure load on the power terminals by transferring the load from the printed circuit board to the module housing, wherein the deformable means include at least one spring element comprising at least one outwardly arched area on which the printed circuit board is seated, the outwardly arched area being adapted to give way in a spring-like manner under pressure, and the spring element comprises clamps adapted to engage the module housing; and at least one contact-pressure element disposed on a side of the printed circuit board opposite the power semiconductor module configured to apply pressure on the printed circuit board, wherein the contact-pressure element is integral with a first housing part of an arrangement housing, and the heat sink is integral with a second housing part of the arrangement housing, the two housing parts enclosing the printed circuit board.
