Abstract: Power module has press-fit pins for the electrical and mechanical connection for the terminals, insertable into sleeves on the substrate. The substrate rests on a baseplate. Potential alignment frame ensures the accuracy of all elements. The mechanical and electrical connection of the power and signal terminals is realized by multiple (high-current) or single press-fit connections. When inserting the pins, they are fitting tightly in these sleeves by overcoming a frictional force and after fitting is established, for each single pin-fit, an electrical contact over a surface is established.
