  • Publication number: 20220013371
    Abstract: 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.

  • Patent number: 10910296
    Abstract: A lead frame is provided, including one or more power terminals and one or more control terminals, wherein at least one of the control terminals is externally terminated with a press-fit contact member, and wherein at least one of the control terminals and at least one power terminals are formed from different materials. With the disclosed lead frame of the invention, lower material cross sections in the power terminals will be provided because of the better electrical conductivity when using pure copper compared to alloys with higher mechanical strengths. Also specific/different plating could be added to the individual needs of the different pin types without using masks in the plating process.
