  • Patent number: 11894292
    Abstract: A power module can include a casing mounted to a baseplate that contains a substrate with circuitry. The circuitry can include pins for coupling signals to/from the circuitry. These pins can extend through a cover portion of the casing so that an electronic substrate, such as a printed circuit board (PCB) can be press-fit onto the pins. When press-fit, the electronic substrate is supported and positioned by support pillars that extend from the base plate to above the cover portion of the casing. If the pins and the support pillars have different coefficients of thermal expansion, damage to connection points between the pins and the circuitry may occur. Here, a power module is disclosed that has thermally matched pins and support pillars so that when the system is thermally cycled over a range of temperatures, the connection points are not damaged by forces induced by thermal expansion.

  • Publication number: 20230369176
    Abstract: Implementations described herein are related to a semiconductor device package having an improved baseplate. In such an improved baseplate, there is a recess cut out of a region of a surface of the baseplate such that the recess has a first sidewall having a first thickness above a recess base and a second sidewall having a second thickness above the recess base. A substrate, e.g., a direct bonded copper (DBC) substrate, may be attached to the baseplate at a recess base using, e.g., a solder layer between the recess base and a surface of the substrate.

  • Patent number: 11804421
    Abstract: A semiconductor package assembly having a connecting clip disposed on both a first material stack and a second material stack having different thicknesses and disposed on a conducting substrate. This connecting clip has a first portion disposed on to the first material stack and second portion disposed on the second material stack, such that the surfaces of the first portion and second portion opposite the conducting substrate are at the same perpendicular distance from the conducting substrate. For example, in some implementations, when the thickness of the second material stack is smaller than the thickness of the first material stack, the second portion of the connecting clip may include a vertical support disposed on the second material stack to equalize the heights of the surfaces of the first portion and second portion of the connecting clip.
