1. A power module comprising:
a substrate having a top surface with a first trace and a second trace;
a first plurality of vertical power devices and a second plurality of vertical power devices that are electrically coupled to form part of a power circuit;
a first terminal assembly comprising a first elongated bar, at least two first terminal contacts, and at least two first terminal legs that respectively extend between different points of the first elongated bar and the at least two first terminal contacts; and
a second terminal assembly comprising a second elongated bar, at least two second terminal contacts, and at least two second terminal legs that respectively extend between different points of the second elongated bar and the at least two second terminal contacts;
wherein the first plurality of vertical power devices is electrically and mechanically directly coupled between the first trace and a bottom of the first elongated bar of the first terminal assembly; and
wherein the second plurality of vertical power devices is electrically and mechanically directly coupled between the second trace and a bottom of the second elongated bar of the second terminal assembly.
