  • Patent number: 7723244
    Abstract: A method for internal electrical insulation of a substrate for a power semiconductor module having a framelike insulating housing with a cap and having an insulating substrate. The substrate has conductor tracks and power semiconductor components mounted thereon. The power semiconductor components are connected to connection elements, e.g., further conductor tracks or power semiconductor components, by means of bond connections. The method is characterized by the following steps: a) forming the substrate; b) coating the substrate with a viscous dielectric insulation compound in a casting process or immersion process; c) initiating the cross-linking of the insulation compound; d) with the substrate in a suspended position, permitting excess insulation compound to drip off, and securely enveloping the bond connections with insulation compound; and e) placing the substrate in the housing.
