Publication number: 20220013371Abstract: A mold tool 1 is described for molding a semiconductor power module having an electrical contact pin 2 which includes an electrical contact portion 3 for contacting a substrate 4 with another electrical component. The pin 2 comprises a protruding portion 5 being a top-sided pin connector. The mold tool 1 includes a first 6 and a second mold die which, when brought together for molding, form a cavity to be filled with a mold compound for encapsulating electrical components of the semiconductor power module, and a recess 7 in the first die 6 which communicates with the cavity within the second die. The recess 7 is filled with a cushion-like soft material 8 into which the top-sided pin connector is pushed thereinto and completely surrounded by the soft material so that a sealing means is formed that prevents any contamination of the electrical contact portion 3 of the pin 2 by the molding compound introduced into the cavity. Furthermore, a method of manufacturing such a semiconductor power module is described.Type: ApplicationFiled: October 24, 2019Publication date: January 13, 2022Inventors: Zeno Müller, Tino Filipiak-Ressel, Holger Beer, Lars Paulsen, Alexander Streibel
