Abstract:
1. A power semiconductor device comprising: a printed circuit board (PCB) having first and second, opposite sides; a first semiconductor die including a gate, drain and source, the semiconductor die being positioned on a first side of the PCB with the gate being soldered to the PCB; a first conductor spaced from the first side of the PCB by the semiconductor die, the drain of the semiconductor die being soldered to the first conductor; a second conductor spaced from the second side of the PCB by an electrical insulator, the source of the semiconductor die being soldered to the second conductor through solder holes in the PCB and insulator; at least one spring applying a clamping force between the first and second conductors; and an electrically insulating layer of material between the spring and each conductor.
